These Forgefix Pozidriv Self-Tapping Screws are made from A2 stainless steel, which will not corrode, rust or stain with ordinary water like other steel does. Their Pan Head, with a flat under head surface makes the screw ideal to lay flat on sheet material of all types, thus reducing deformation. The screws tap their own thread in a pre-drilled pilot hole, in sheet metal. The screws are single threaded to resist pull-out. APPLICATION Ideal for use in many DIY, ironmongery, engineering, electrical and plumbing applications.Supplied in a handy ForgePack.Select Option 1.1/2in x 10 ForgePack 101.1/2in x 8 ForgePack 151.1/4in x 10 ForgePack 121.1/4in x 8 ForgePack 201/2in x 4 ForgePack 601/2in x 6 ForgePack 601/2in x 8 ForgePack 401/4in x 4 ForgePack 801in x 10 ForgePack 151in x 4 ForgePack 401in x 6 ForgePack 302in x 10 ForgePack 82in x 8 ForgePack 123/4in x 10 ForgePack 203/4in x 4 ForgePack 503/4in x 6 ForgePack 403/4in x 8 ForgePack 303/8in x 4 ForgePack 805/8in x 6 ForgePack 505/8in x 8 ForgePack 35 Add to Basket Quantity
