Description
Overview:
The Sealey Self Tapping Screw 4.8 x 19mm Flanged Head Black Pozi (BS 4174) is a durable fastener for panels, guards and general assembly on construction and garden machinery. Made from case-hardened steel with a black corrosion-resistant finish, it forms its own thread in thin metals and many plastics when used with an appropriate pilot hole. The flanged Pozi head spreads load and reduces the need for a separate washer, helping to protect painted surfaces and plastics from denting. Sized at 4.8mm diameter (approx. 3/16 inch) and 19mm length (approx. 3/4 inch), it suits a wide range of tasks on equipment such as mowers, generators, compactors and small plant. Supplied in a 100-pack for workshop and site use.
