HT Allen Hex Socket Cap Screw:M16 x 140 - DIN 912/12.9/Black/Half Thread

This HT Allen hex socket cap screw is manufactured from high-tensile steel and rated to property class 12.9 for superior strength performance. It conforms to the DIN 912 standard and is available in an M16 nominal diameter with a 140 mm length. The fastener features a half-thread design, allowing the unthreaded shank to pass through pre-drilled clearance holes to increase the effective engagement length in the mating material. A black surface finish is applied to provide visual contrast and basic corrosion resistance for the steel body. Buyers select this grade and size when high shear strength is required for heavy-duty mechanical assemblies where standard lower-grade fasteners would fail. Choose this specific dimension and finish when your design requires a long-reach, high-load fastener with a half-thread configuration.
