Product Description
7/16″ UNC High Tensile Countersunk Socket Screws – Self Colour
7/16″-14 UNC countersunk socket screws manufactured from high tensile alloy steel with a self colour finish. The flat countersunk head provides a flush finish when installed in a correctly prepared matching countersink.
These imperial coarse-thread screws feature an internal hexagon drive for use with a 1/4″ Allen key or hex bit.
