SS Hex Head Bolt:M4 x 20 - DIN 933/A2/Full Thread

This M4 x 20 hex head bolt is manufactured from A2 stainless steel, conforming to the DIN 933 standard for metric hexagon head bolts. The fastener features a nominal diameter of M4 and a nominal length of 20 mm, with a full thread coverage along the shank. Buyers typically select this component for its corrosion resistance provided by the A2 stainless steel grade, making it suitable for environments where rust prevention is a priority over higher strength requirements. The standard hexagon head design allows for secure driving with common wrenches, while the full thread ensures consistent grip in various material thicknesses. To choose the correct size, specify the M4 thread diameter and 20 mm length to match the application requirements.
