These RS PRO screws are thread forming screw fasteners that require a pre-drilled or pre-punched pilot hole to connect or attach objects to or mount on vertical or horizontal surfaces. You can use them when you need to frequently disassemble and reassemble goods as they cut their own precise thread when fastened.
The clear-passivated zinc plating forms a barrier around the galvanised steel to protect it against corrosion to ensure these screws won't tarnish or rust, so they last longer. You'll get better surface contact and a more secure connection with the broad, flat base of the pan-head design.
This product has a Restriction of Hazardous Substances (RoHS) certificate, which means it contains only minimal amounts of any harmful substances. You can use these screws with ductile metals that can flex and deform without cracking or breaking.
