3mm x 8mm Torx Countersunk PT45 Screw for Hard Plastics | A2 Stainless Steel
Built for consumer electronics and appliance housings, this 3mm x 8mm PT45 Screw uses A2 Stainless Steel, a T8 Torx drive and a Countersunk head. The specialist thread form is designed for harder plastics where a strong drive-to-strip ratio and flush installation are useful.
What Are Torx Countersunk PT45 Screws?
