HT Allen Hex Socket Cap Screw:M16 x 20 - DIN 912/12.9/Black/Full Thread

This high-tensile steel fastener is a hex socket cap screw manufactured to the DIN 912 standard, featuring a property class of 12.9 for superior strength. The M16 diameter and 20mm length designation identifies the specific size, while the full thread coverage ensures maximum engagement across the entire shank. A black surface finish provides a protective layer, and the socket drive design allows for high torque application with a hex key. Buyers select this grade when heavy loads and secure retention are critical in mechanical assemblies. To choose the correct part, verify the required nominal diameter and length, confirm the 12.9 strength rating is necessary for the application, and ensure the black finish and full thread specification match your assembly requirements.
