These 5.5 x 50mm SuperTEK 7 heavy-duty self-drilling metal screws are designed for steel-to-steel fixing in heavy-gauge sections. The TEK 7 spiral drill point allows drilling and fastening in suitable steel without a separate pre-drilling operation.

The fine 24 TPI V-fluted thread is designed for engagement in steel, and the hex head provides positive drive with a suitable 8mm socket. The 1000hr-rated EvoShield coating offers protection for the carbon-steel fastener.

The 50mm product has a fully threaded section according to the Evolution technical datasheet.

This version is supplied without a bonded sealing washer. It suits applications such as brackets, framing components and steel-to-steel connections where a separate weather-sealing washer is not required. For demanding structural connections, verify design requirements and installation conditions.
