Self-drilling Screws

Drill their own hole and tap their own thread.

Buildex® self-drilling screws are specifically developed for various applications. They provide high pullout strength, shear strength and maximum thread engagement and positive fastening in both structural steel and timber constructions.

Time saving
Assembly and on-site labour time is greatly reduced by eliminating the task of alignment or the need to pre-drill holes. Fastening operations in roofing, cladding and assembly can be completed in less time, often halving the time of the old conventional method.

Easy to Use
Utilisation of unskilled labour is another benefit due to the engineering design of this type of fastener, as selection of drill size and various tools are eliminated. The tradesman will also realise the benefits of speed and ease of installation.

One operation
As the fastening is reduced to one operation, alignment problems are eliminated. It is more economical to use self-drilling screws than to drill, tap and fasten or nut and bolt in the traditional manner.

Screw guns
Best results are obtained with electric screw drivers (TEK Guns) of approximately 380 to 650 watt rating, operating at 2500 rpm.

 

 

A TEK Screw is a screw that has a tek at the end of the shank. The tek 'self drills' and thus needs no pilot hole. These screws are similar to sheet metal screws but do not come with the sharp point.
