Hexagon Head Bolts, Full Thread

Product Description

Hexagon Head Bolts, Full Thread manufactured to DIN933 specifications are designed for applications requiring full thread engagement along the entire bolt length, ideal for through-hole assemblies. The standard hex head geometry allows installation with common hand or power tools. Available in sizes M4-0.7 through M12-1.75 with lengths from 8-40mm to 20-150mm, covering the most common range for industrial assembly applications. Custom sizes outside standard ranges can be produced for OEM customers with sufficient volume requirements. Material options include 4.8, 8.8, 10.9, 12.9, SS A2, SS A4. Carbon steel grades 4.8, 8.8, and 10.9 cover general purpose through high-strength structural applications. Stainless steel A2 (304) and A4 (316) provide corrosion resistance for marine, food processing, pharmaceutical, and chemical environments. Brass is available for electrical and decorative applications requiring non-magnetic properties. Surface treatments include zinc plating (Z.P.L), black zinc phosphate (B.Z.P), nickel plating (Ni.P), Decromet, Ruspert ceramic coating, and hot-dip galvanizing.

Typical applications span automotive assembly and chassis construction, machinery manufacturing, structural steel connections, precision equipment and instrumentation, mold and die making, construction and infrastructure, and general engineering industries. These fasteners are designed to meet or exceed applicable international standards for dimensional accuracy and mechanical performance. Aufaster supplies these products in bulk packaging with full material traceability per EN 10204 Type 3.1, dimensional inspection reports, and mill test certificates available on request. Custom sizes, special materials, and non-standard finishes are available for OEM customers with volume requirements.
