These 5.5 x 50mm SuperTEK 7 heavy-duty self-drilling screws are designed for steel-to-steel fastening in heavier steel sections. The supplied 16mm EPDM bonded sealing washer makes this a washered option for applications where a seal at the fixing point is required.

Evolution specifies a 24 TPI V-fluted thread and an 8mm hex head for a suitable non-impact socket drive. The C1022 carbon steel screw has a 1000hr-rated EvoShield coating.

The TEK 7 spiral point is specified for drilling 4.0–18.0mm steel. It offers a washered alternative to the unwashered SuperTEK 7 screws for steel framing and component fixing where a sealing washer is required.
