Self Tapping Screws
Self tapping screws are often referred to as self tappers or PK'S as many of them were orginally manufactured by the Parker-Kalon company. In America they are known as sheet metal screws as they are for use in sheet metal up to 3mm in thickness. Sucessful installation is dependant on the correct size of hole being drilled or punched to suit both the diameter of screw and also the gauge of sheet metal that screw will be fitted to, this will prevent head shear and make installation effortless. Self tapping screws are available from Orbital Fasteners in Countersunk Pozi to DIN 7982, Pan Pozi to DIN 7982 and Flange Pozi to DIN 4174, we stock each product in steel bright zinc plated and stainless steel.
