a) A weld screw is a fastener specifically designed for welding onto metal surfaces, particularly steel. It is coated with a thin layer of copper, which enhances conductivity and improves weld quality by ensuring a strong and consistent bond.
a) A ribbed neck screw is a type of fastener designed with a special feature on its shank or neck. Instead of a smooth or threaded surface, the neck of the screw has ribbed, serrated, or knurled features. These ribs or serrations provide additional grip and resistance when the screw is driven into a material, preventing it from rotating or loosening.
