COACH SCREW (DIN DIN 571): Have a coarser pitch than sheet metal or machine screws, and often have an unthreaded shank. These are facilitated with another fastener to tighten the grip from the opposite end.
The coach screws offered by us are specially designed for the purpose of joints of metal and timber. The fine finish of these screws provides easier driving and reduced splitting.
