HT Hex Head Bolt:M18 x 300 - DIN 931/8.8/Black/Half Thread

This heavy-duty fastener is an M18 hex head bolt manufactured from steel with a nominal length of 300 mm. It is standardized to DIN 931 specifications and features a property class of 8.8, indicating a medium strength grade suitable for general structural and mechanical applications. The bolt exhibits a half-thread design, which provides better clamping stability in the unthreaded shank area compared to fully threaded alternatives. A black surface finish is applied to the steel material, offering a standard appearance for industrial environments. Buyers select this specific configuration when a robust connection is required at a depth of 300 mm without the need for full-length threading. To choose the appropriate fastener, verify that the M18 nominal diameter fits the mating hole, the 8.8 property class meets the load requirements, and the half-thread coverage aligns with the assembly’s depth constraints.
