M4 M5 M6 Hexagon Socket Head Cap Screws With Lock Washer And Plain Washer Metal Sems Screw Din912

Product Description

These SEMS screws feature a hexagon socket head cap (DIN912) combined with both a spring lock washer and a plain flat washer pre‑assembled. The spring washer sits above the flat washer to provide vibration resistance while the flat washer protects the workpiece surface. Made from carbon steel (8.8/10.9/12.9) or stainless steel (A2/A4) with finishes such as zinc plating, black oxide or plain. Sizes M4, M5 and M6 are the most common for precision machinery, moulds and electronic equipment. The socket head allows high torque transmission and is suitable for countersunk or recessed holes.
