Galvanized Allen Bolt
Galvanized Allen bolts are typically made from carbon steel grades 8.8 and 10.9, with tensile strengths ranging from 800 to 1040 MPa. The bolt diameters vary from 4 to 24 millimeters, and lengths range between 10 and 200 millimeters. These bolts are manufactured according to DIN 912 and ISO 4762 standards and feature an internal hexagonal head with a 90-degree angle. Cold or hot-dip galvanizing coatings enhance corrosion and rust resistance in humid and industrial environments. Heat treatment improves mechanical strength and durability against dynamic and static loads.
The threads of galvanized Allen bolts are produced with precision tolerances of ±0.15 millimeters based on ISO and DIN standards. Thread pitch typically ranges from 0.7 to 2.5 millimeters and is available in full-thread or half-thread versions. Surface hardness after heat treatment and galvanizing reaches 35 to 45 HRC, providing high wear resistance and preventing plastic deformation. These bolts are widely used in construction, automotive, and industrial equipment sectors for connections requiring high strength and long-lasting durability.
