HT Allen Hex Socket Grub Screw:M3 x 6 - DIN 916/12.9/Black

This hex socket grub screw is manufactured from steel and conforms to the DIN 916 standard, featuring a property class 12.9 designation that ensures high tensile strength for demanding applications. It measures M3 in nominal diameter with a nominal length of 6, making it suitable for precise mechanical fastening tasks. The component includes a black surface finish, which helps reduce visibility of minor surface imperfections and offers a distinct visual marker for maintenance teams. Buyers select this grade when high-load resistance is required in compact assemblies, such as in precision machinery or automotive components where space is limited. To choose the correct size, ensure the M3 diameter aligns with your mounting hole and that the 6mm length provides sufficient engagement without interfering with adjacent parts. The hex socket drive allows for secure tightening using a standard Allen key, ensuring the screw remains seated under vibration.
