Screws

Self-drilling tek screws are the fastener of choice for joining sections of spiral ducting and fittings on site — the hardened drill point cuts its own hole through sheet steel, so there is no separate drilling and no swapping bits between fixings.

We supply tek screws in a trade box of 1,000, complete with a drill bit for your driver, so one box keeps an installation team going all week. They are ideal for securing duct joints, fixing support clips and general sheet-metal fixing throughout a ventilation installation.

Seal the finished joints with duct sealant or foil duct tape, and browse the rest of our fasteners, fixings and accessories for everything else the job needs. Order by 3pm for next-day delivery on stocked items.
