Reliable SD500® Self Drilling Screws for Metal

SD500® TEK self-drilling screws 12g-24 with an extended drill point for metal. Ideal for thick steel section, purlins and hot rolled steel commonly used by steel fabricators, builders, plumbers and HAVAC industries.

SD500® screws are a great option over other standard tek screws with there increased capacity to drill steel 3.0mm up-to 12.0mm. Designed to fix metal to metal, this can be achieved in a single piece of 12.0mm steel or by multiple pieces or by two pieces of steel with an air gap.

The hardened drill tip provides consistent and reliable drilling without the need of pilot holes. With consistent firm pressure the extended drill tip centers and drills steel pulling the screw into the fixture as threads hold on ensuring maximum pull-out strength.

When fixing timber to thick steel the SD500® screws range is a great option providing all the same performance with a flush finish.

Our range covers common head types in ruspert class 3 coating great for most applications. For when high-corrosive environments are specified our SD500® bimetal range provides properties of 300 grade stainless steel with the same drilling capacity.
