SS Allen Hex Socket Cap Screw:M3 x 45 - DIN 912/A2/Full Thread

This fastener is an Allen hex socket cap screw machined from stainless steel to meet the DIN 912 standard. It features a nominal diameter of M3 and a nominal length of 45, with a full thread design that ensures secure engagement throughout the shank. The A2 property class designation indicates a standard grade of stainless steel suitable for general indoor applications where moderate corrosion resistance is required. Buyers select this type of screw for its clean, flush head appearance when recessed and the compact drive provided by the hex socket. To choose the correct size, verify that the M3 diameter matches your threaded hole and confirm the 45 length provides sufficient clamping force for your specific assembly depth.
