Full-formed threads within one pitch of the head improve strip-out ratio and special serrations under the head increase strip-out torque. A radius point prevents the screw from drilling its own hole in misaligned assemblies and eliminates sharp points that can cause injuries or cut wire insulation. The screws are available in standard head styles with diameters ranging from #6 through 5/16 in.
