Product Description
Hex nuts are standard internally threaded fasteners used with bolts, threaded rods and studs in construction, machinery, equipment, automotive and general industrial assemblies. This range covers DIN 934, ISO 4032 and SAE J995 references in 10B21 / 35K with Grade 8 / 10 / 12 options.
Nut selection should confirm standard, thread size, strength grade, proof load, coating, mating bolt grade and whether the assembly requires a standard nut, flange nut, lock nut or heavy structural nut. General hex nuts should not be substituted for structural or pressure bolting nuts when those standards are specified.
Zinc plated finish is common for indoor and mild-service assemblies. M3-M30 sizes can be supplied alone or kitted with hex bolts, threaded rods, flat washers and spring washers for project procurement.

FAQ
Common references include DIN 934, ISO 4032 and SAE J995, depending on metric or project requirements.
The nut grade should match the bolt grade and joint requirement. Grade 8 / 10 / 12 options are available.
Zinc plating is mainly for indoor or mild environments. Outdoor or severe corrosion applications may need another coating or material.
They are general hex nuts. Structural projects may require ASTM A563, EN 14399 or other dedicated nut standards.
Yes. Hex nuts can be supplied alone or as bolt-nut-washer sets.
Send size, grade, standard, finish, quantity and matching bolt/washer requirements. We can quote M3-M30 zinc plated hex nuts for project kits and industrial assemblies.
