HT Hex Head Bolt:M4 x 75 - DIN 931/8.8/Black/Half Thread

This hex head bolt is manufactured from steel and designated as Property class 8.8, ensuring a specific balance of strength and ductility for general structural applications. It complies with the DIN 931 standard, which specifies a partial thread covering approximately half of the nominal length. The bolt features an M4 nominal diameter and a 75mm nominal length, finished in black. Buyers select this component for fastening tasks requiring moderate load-bearing capacity in machinery or frameworks where full-threaded alternatives offer no additional benefit. To choose the correct size, verify that the 75mm length allows the threaded section to engage the nut or tapped hole fully, leaving the unthreaded shank for the main clamping surface.
