HT Allen Hex Socket Cap Screw:M18 x 180 - DIN 912/12.9/Black/Half Thread

This heavy-duty fastener is a steel hex socket cap screw manufactured to the DIN 912 standard, featuring a property class of 12.9 for high tensile strength. It is supplied with a black surface finish and a half-thread design, which allows the unthreaded shank to provide additional support and prevent thread stripping in softer mating materials. Buyers select this specification for applications requiring robust load-bearing capacity and secure retention where full threading is unnecessary or undesirable. When selecting this fastener, verify that the M18 nominal diameter and 180-unit nominal length align with your joint requirements, ensuring the 12.9 grade meets the stress limits of your assembly. The half-thread configuration specifically aids in installations where the shank engages deeper into the material than the thread length, offering a distinct advantage over full-thread alternatives for structural stability.
