At Cladco, our self-drilling TEK screws have a 5/16th hexagonal head for attaching sheets to heavy section steel purlins. Under the screw head, is a stainless-steel washer and bonded neoprene pad to create a seal with the sheet. It is vital to use the correct TEK screws and TEK fixings for the correct sheets and purlins; if you’re unsure then we can help point you in the right direction.
Don’t hesitate to contact us with any queries you may have about our TEK fixings and TEK screws.
