RS PRO Steel 680 Piece Hex Drive Screw/Bolt Kit

From the trusted professional brand, RS PRO, this set of high-quality hex head self-drilling hexagon drive screws are ideal for many applications. Self-drilling screws are very similar to self-tapping screws, however self-drilling screws have the added feature of a drill point end. Self-drilling screws eliminate the need for a pre-drilled pilot hole as they perform the drilling, tapping and fastening in one action. The hardened steel fixings are generally used when fixing metal to metal or metal to timber.

Self-drilling screws are traditionally used where an application requires regular maintenance and regular easy access. These screws are useful in situations where products must be assembled and disassembled, such as access panels or even furniture.

These self-drilling screws are made from BZP (Bright Zinc Plating) galvanised steel, which is one of the most common finishes for the majority of fixings. This thin layer offers galvanising protection to the steel, preventing rust and oxidation except in outdoor environments.

In this kit, you will find 680 self-drilling hexagonal drive hex head screws, in thread sizes 4.2mm, 4.8mm and 5.5mm, with lengths ranging from 13mm to 38mm.

• Thread-cutting self-drilling screws with pan and countersunk heads to DIN7981 & DIN7892 standards.


• Hexagonal drive type


• BZP galvanised steel


• Generally non-magnetic


• Cannot be hardened by heat treatment


• Supplied in a polypropylene case with a hinged cover

The bright finish of BZP steel offers a uniform appearance and protects the steel beneath it from oxidation or rust, however the BZP layer itself is very thin and is susceptible to rust itself in outdoor environments. As self-drilling screws allow the drilling and fastening to be completed in one motion, they are particularly useful in applications where accuracy and speed are of the essence. Some of the most common environments include:

• Cladding and roofing


• Metal (including steel) and wood frames


• Car production lines


• Sheet metal work
