Description TEK Screw Hex Head Coarse Thread can be used to fix steel roofing or plate to wood. The self-drill point of the fastener drills the perfect pilot hole for the thread to grip into the wood. This particular product is very popular in a number of carpentry projects since it is basically a self threading product cutting back on the number of steps necessary to complete projects. Carpenters use them for screwing metal into wood or even screwing metal into metal depending on the thickness of the material. TEK Screw Hex Head Coarse Thread allow the user to screw two pieces of material together without drilling a hole before hand as you would if you were using a normal drill.
