Head Bolt

Allen Button Head Bolt is a low-profile socket cap screw featuring a wide, dome-shaped head with an internal hex drive. The reduced head height makes it ideal for applications where a standard cap screw head would be too prominent or interfere with adjacent components, providing a clean, flush appearance in visible assemblies.

Manufactured from high-quality stainless steel (SS 304/316) and alloy steel in grade 8.8 and 10.9, these screws conform to ISO 7380 standards. They are widely used in automotive panels, electronic enclosures, machinery guards, and architectural fittings where aesthetics and space constraints are equally important.

Grade: 10.9 / 12.9 M3 – M20 SS304 / SS316 ISO 7380 Hex Socket Drive
