Wing Tip SD Screws Torx Drv Bimetal 316 Stainless

Wing Tip SD Screws Torx Drv Bimetal 316 Stainless

Ideal timber-to-metal self drilling screw.

Marine grade 316 bimetal stainless screws have a high-corrosive resistance and are preferred material type in coastal and other corrosive environments. These winged tip self-drilling screws are capable of fixing timber to steel battens in decking and cladding applications.

Made from 316 series stainless steel with a heat treated hardened drill tip for the purpose of drilling into steel – up to 6.0mm thick.

Our torx head bimetal screws have a single layer zinc plated surface coating therefore will not appear to have a typical stainless steel look. This is simply part of our manufacturing process ensuring a high level of corrosion protection, whilst ensuring drilling performance is maintained.

Other features include a winged tip, this clears a hole in the timber surface to enable the countersunk head to sit neatly flush. The torx drive allows maximum pressure to be applied during installation without cam out or damage to the screw head and driver bit.
