Product Number: ST3516
When you need a clean, flush finish without the cost or complexity of specialist fixings, a reliable self tapping screw is essential but poor quality fasteners can cam out, shear, or fail to cut thread cleanly. The Sealey ST3516 is a countersunk Pozi self tapping screw measuring 3.5 x 16mm, manufactured to DIN 7982 for consistent quality and thread form. The countersunk head sits flush with the surface for a neat result, while the Pozi drive provides good bit engagement and reduces the risk of slipping. Supplied in a resealable bag in a pack of 100, keeping your workshop stock tidy and ready to use.
