Series 500 Screws

The Single-Action Self-Driller for Metal

Looking to save time on attaching metal to metal, and gain serious clamping strength at the same time?

Series 500 screws are designed to fix metal to metal, and sometimes timber to metal, through thicknesses of up to 12mm in total, without the need for pre-drilling.

These screws, a great alternative to standard tek screws, allow you to save on broken drill bits and user fatigue by allowing you to embed the fastener in to its own self-drilled hole – one push, one screw done. The extra-long drilling tip—12mm—guides the remainder of the screw through just before the thread takes hold and taps itself in. It is essentially a drill point and screw in one.

But what sets this apart from other self-drillers?  

This:

• Dual-hardened carbon steel for superior strength  
• A choice of head types to suit any situation – hex, countersunk and wafer – and for all common driver bits
• Option of bi-metal stainless for superior corrosion resistance

The Nitty Gritty

The majority of the Series 500 screws we offer are 12g in thickness and feature a 24 TPI thread, to remain consistently compatible across many jobs where other fasteners may also be present.

On a coarse thread – 2.5 to 3 times the drilling capacity of a normal self-driller. That is, through 3 times the thickness of the material. On a fine thread, 2 times.

Best Practice for Using Series 500 Screws

Series 500 screws are great for use in roofing, fencing and steel fabrication work. In fact, any job where time is tight but you need to fasten tough metals. To get the most out of these screws, however, there are some simple tips and techniques for getting them in fast and without damaging them.
