Unfortunately, buying anchors online is not possible yet. We are doing our best to add this feature in the future. However, you can submit a request for proposal using our products page.

EasyFix is a free-of-charge program which you can download here or register for our Pro version.

EasyFix can be used to choose suitable anchors and determine their required number according to design parameters. The program allows you to select anchors for concrete applications as well as for walls with masonry and concrete elements, to choose suitable fixing solutions for safety barriers and for fixing insulation materials on flat roof. Another program feature enables you to calculate the right amount of resin to be applied while fixing a rod in a hole. The EasyFix program is continuously being expanded with further modules.

Blocks in the .dwg format can be generated using the EasyFix program which you download free of charge here.

R-KEX and R-KER resins are tested and CSTB certified for fire resistance properties.

R-KEM II and R-KER resins are supplied in packaging which enables their application by means of standard caulking guns. However, you should keep in mind that the force required to squeeze the resin out of its container is much higher than that applied to inject standard silicone. Consequently, your caulking gun should be robust enough not to get damaged in the process.

R-KEX II bonded anchors can be used in diamond-drilled holes.

Rawlplug’s resins can be installed in water-filled holes. Products such as R-KEX II, R-KER, R-KEM II, R-KF2, R-CFS+, RM-50 and RP-30 are epoxy, polyester and vinyl ester resins. The European Technical Approval of these products contains relevant entries on the conditions of use of these resins.

The number of fixing operations you can perform using resin depends on the hole diameter and the resin container size. We recommend that you download the  EasyFix program or register for our Pro version, which features an accurate resin consumption calculator.

Heating an anchor to high temperatures will exert a negative effect on its load capacity. While welding, you should ensure optimum weld cooling in order to control heat transfer to the anchor.

Bonded anchors differ in terms of suitable tightening torques on account of the rod diameter and the substrate type. Refer to the products page to find the installation parameters for your selected product. Read the appropriate tightening torque value based on the rod diameter.

Each resin has its own characteristic setting time, which is influenced by a number of factors. This includes the chemical composition of the resin, substrate and external temperature. Setting times of a Polyester resin is SHORTER than that of a pure epoxy. Refer to the products page for detailed information on setting times of individual resins.

Metal or plastic mesh sleeves need to be used when anchoring a threaded rod into hollow substrates. Individual threaded rod diameters require specific sizes of the mesh sleeve and can be found in the TDS or ETA of the product.

With cracked concrete, use type R-KEX II, R-KER, R-KER-II and CFS+RV200 resins.

R-KEX II, R-KER, R-KER-II, RV200 and R-HAC-V can be used with rebars.

The mechanical anchors tested for fire resistance are:

No. With R-DCA anchors, you should only use a setting tool of appropriate diameter (i.e. matching the anchor diameter) supplied by Rawlplug.

.For fixing applications in substrates made of materials other than reinforced concrete and concrete, use the R-RB mechanical anchor.  It is suitable for substrates such as class C20/25 hollow-core concrete slabs, solid brick of class ≥ 20, calcium silicate brick of class ≥ 15, lightweight hollow concrete blocks of class ≥ 5 or hollow concrete blocks for rib-and-slab floors.
You will find more detailed information about the R-RB anchor in the products tab.

It is possible to use R-HPT-ZF instead of A2 or A4 stainless steel anchors after consulting with technical support.

Yes. Type R-LX concrete screw anchors are suitable for multiple application.

According to ETAG, zinc-plated mechanical anchors are not suitable for outdoor applications. You can only use stainless steel anchors outdoors. You will find information about stainless steel anchors in the products page. However, upon previous consultation with the technical advisor and under specific conditions, the R-HPTII-ZF anchors are conditionally approved for these applications.

Yes. Zinc-plated mechanical anchors are suitable for fixing of aluminium elements?

It is recommended that drilled debri is removed from the hole using a manual blow pump, 4 times.

Graphical instructions of hole cleaning are provided in the products page along with technical specifications of each mechanical anchor.

Mechanical anchors are characterised by specific tightening torques which differ depending on the rod diameter and the substrate type. Refer to the products page to find the anchor you use and the corresponding table containing installation parameters. Read the appropriate tightening torque value based on the rod diameter.

The minimum zinc coat thickness is 5 μm, while the R-HPTII-ZF anchors are coated with at least 12 μm of zinc.

C4. Upon consultation with our technical consultant they can also be used as for the C5 category.

We recommend using a torque wrench for tightening of mechanical anchors, to ensure the required torque is achieved. By using a screw gun or other tools, you may damage the anchor or install it improperly which can result in a reduction in the load capacity of the anchors.

The following mechanical anchors can be installed in cracked concrete:
You can find more detailed information about our products in the products page.

Our fixings can be used in environments of different corrosion categories, from C1 to C5. Individual types of fixings have been tested for compliance with the following categories:
C3 – WBT
C4 – WB, WO
C5 – WX

Fixings should be stored loosely with enough space, so that they do not get crushed. You should handle long sleeves particularly carefully, as they can be subject to deformation and twisting. Additionally, nylon fixings should be secured against damping prior to installation.

The number of fixings used on roofs depends on several factors, including the wind zone where the given roof is, the roof height from the ground and the building foundation altitude above sea level. In order to determine the correct number of fixings, we recommend you to perform suitable calculations in the RooFix program, which is available here, or to contact the technical helpdesk, as provided below.

Provided that the substrate is made of concrete, you can fix insulation materials with the thickness of up to 980 mm using our roofing insulation fixings, in which case the solution of choice is GOK-725 R-WBT-61300. You will find detailed information about this product in the products page.

The fixings intended for concrete applications are R-WBT or R-WCS. You will find more detailed information about these products in the products page.

You should use R-WO and R-WW fixings. You will find more detailed information about our products in the products page.

R-WO, R-WBT are WW fixings are intended for wood. You will find more detailed information about these products in the products page.

Using deep-set hammer-in fixings along with the KES insulation retaining caps makes it possible to avoid the spotted facade effect. You can use a number of products for deep-set installation, including the KI-10M pin. You will find more detailed information about this product in the products page.

For purposes of fixing into ventilated facades, you can use various solutions, including KWL insulation retaining plates and WBT screw-in fixings. You will find more detailed information about our products in the products page.

Yes. This type is fixing is available upon request.

KWL flanges are designed to increase the pressure surface area. They are recommended for fixing of lamella wool, and they can be used together with TFIX, KL and KC fixings.

The fixing solutions which you can use for additional insulation purposes include the following products: TFIX-8M, TFIX-8S, KI-10N, KI-10NS, KI-10M. You will find more detailed information about our products in the products page.

The minimum embedment depth for facade pins is 25 mm. You will find detailed information about correct anchoring depth for facade pins in the products page.

Laboratory tests have revealed that spacing of fixing pieces depends on a number of factors:
• Weight of the thermal insulation material, including glue, mesh and plaster,
• Type of material that the load bearing structure is made of,
• Height of the building being insulated.

In order to obtain the optimum number of connectors it is advisable to make calculations in EasyFix program.

For making holes in ceramic substrates such as horizontally perforated bricks or gas concrete blocks, we recommend you to avoid percussion drilling. Refer to our products page for drilling depths.

All facade insulation fixings are suitable for lamella wool as long as they are used with the recommended KWL insulation holding flange of 90 mm, 110 mm and 140 mm in diameter. You will find detailed information about these fixing solutions in the products page.

On steel substrates, we recommend using the FS and WS screws, while you should use the FT screws on wooden substrates.  You will find more detailed information about these products in the products page.

Increasing the embedment depth will not have a significant positive effect on the fixing load capacity, but it will in fact reduce its thermal insulation properties by creating a larger heat leakage bridge.

No. Plastic plugs are not suitable for fixing in floor slabs. To achieve adequate fixing quality, you are recommended to use mechanical anchors.

Fixings including a plastic plug and stainless steel screw are suitable for outdoor applications. Moreover, R-FF1-ZF fixings can be used conditionally, but it is recommended that you first contact the technical advisor before installation.

You should not use the KMW fixing for suspended ceiling applications. Instead, we recommend you to use the R-GS anchor.

Yes. Rawlplug has universal plugs in its product portfolio. They are marked as 4ALL, UNO, FIX and FX.

For fixing in solid as well as hollow substrates, use R-FF1 and R-FX-A2 stainless steel frame fixings.

Both UNO and 4ALL are lightweight plastic wall plugs. During installation, the expasion effect with the 4ALL fixing takes place in the middle of the plug, whereas FOR the UNO fixing, it takes place near the collar.

Nylon plugs are made of polyamide.

The fixing solutions recommended for drywall applications are FS and WS screws (on steel substrates) or FT screws (on wooden substrates). You will find more detailed information about our screws in the products page.

You should not cut the excess thread off after installing a self-drilling screw, as this will cause a corrosion centre to emerge and weaken the screw structure.
