Fast and direct light-duty installations on concrete with the new BTS4

BTS concrete screws

Meet the BTS4 Concrete Screw

The BTS4 is a 25 mm concrete screw with a Ø4 mm and a TORX 20 tip for fastening light loads up to 60 kg, with a low setting depth of only 18 mm. It enables a direct fastening in concrete without the need to use plugs. 

It comes in a ready-to-install set including a matching SDS drill bit with 4 mm diameter and 110 mm length.

Advantages of the BTS4

Save time: Direct and fast fixing, with an all-you-need, ready-to-install set that includes the SDS Drill Bit

Innovative thread geometry: it enables the possibility of manually installing it without a battery screwdriver

Smart installations: suitable with gas nailer accessories and a problem solver in case of gas nailer setting errors

Expansion pressure-free anchor: ideal for low edge and spacing distances.

BTS4 and Gas Nailing

The BTS4 is the perfect supplementary product for gas nailing systems since it provides a solution when:

• A shot is missed with the gas nailer due to tough concrete, nail bending, or concrete breakage.
• Gas nailing is impossible because the base material is too soft or fragile.

It is completely compatible with gas-nailing accessories with a removable plastic base, such as the metal clips PFT, and DFT, or the metal cable clamps CHS, which are specially designed for direct fastening with gas nailers. Here, BTS4 enables installation in the same place and reuse of the same accessories in the event of nail setting failure by simply removing the plastic base part as in the picture and installing it with the BTS4.

Understand the BTS4 Head type


The design of the pan head allows for a flush finish against the fastening application, meaning it can be used in a wider variety of applications.
