Stainless Steel Countersunk Hexagon Socket Bolts

Stainless steel countersunk hexagon socket bolts (Allen countersunk bolts) adopt a tapered countersunk head design, which can sit flush with the workpiece surface after installation without protruding. Made of 304 or 316 stainless steel, they feature excellent rust and corrosion resistance. The internal hex drive enables easy tightening in narrow spaces. Widely used in machinery, cabinets, and equipment where a flat surface is required for reliable fastening.
