Screws and Fixings

Our Range Of Fixings

In the building and maintenance industry screws and fixings are used every day. The posi-drive head countersunk screws are the most popular and used by almost everyone at work and in the home. Like the wood screw some fixings are used by everyone and some have been designed for specialist installations. Each trade has its own range of nuts, bolts, washers and other fixings that it uses regularly and sometimes exclusively.

Some fixings are made from brass and some from steel with either a black, zinc, galvanised or chrome plated finish. They are all different shapes and each one has a different head. The heads can be countersunk or panhead and there are others including raised head and round head. The posi-drive heads are anti-slip which is useful when working on finished surfaces or expensive equipment. (continued below)

We have listed the screws and fixings that we stock with a short description of their uses.

Posi-Drive Wood Screws

A very common fixing that can be used with all types of wood. They are made from hardened steel, have a twin thread and a sharp point for fast starting. This means pilot holes do not have to be made when used with most building materials.

Black Japan Roundhead Screw

This type of fastening is often used by electricians to fix conduit boxes and trunking. The Black Japan roundhead have no sharp edges that can slice through cables as they are pulled in during wiring.

Brass Roundhead Screws

The larger variety are often used outdoors to fix bulkhead lights and IP rated switches and sockets. The small brass roundhead is used to clip bare and PVC covered MICC pyro cables on the inside and outside of buildings.

3.5mm Raised Head Screw

These are used to fix switches and sockets to flush or surface metal boxes. The 3.5mm raised head are available in different lengths to enable electrical accessories to be fixed to metal boxes that have been flushed deep in the wall.

4mm Panhead Screws

In the electrical trade, the 4mm panhead is used for fixing box lids, light fittings and various other equipment to steel conduit boxes. There are about five different lengths for reaching conduit boxes flushed into concrete, as well as nuts and washers to help with other tasks.

2BA Roundhead Screw

In old steel conduit installations the conduit boxes were threaded for 2BA and some of these installations are still in place. You will find them in old buildings, often in floor and ceiling screeds where they were installed for lighting and power circuits.

Gutter Nuts And Bolts

Known for their versatility, gutter nuts and bolts can be used to couple together or securely mount one item to another. They are used by builders and contractors of every trade as well as the DIY enthusiast.

Self Tapping Screw

A range of small screws in three lengths with either panhead or countersunk head. They will self-cut a thread into small holes drilled in light metals and many other materials.
