Zinc-Plated Metric Hex Nuts (DIN 934)
Zinc-Plated Metric Hex Nuts (DIN 934)
Secure bolted joints, threaded rod suspensions, machinery mounts, and pipe support assemblies with our Bright Zinc-Plated Hexagon Nuts (DIN 934 / ISO 4032). Precision-machined from high-tensile carbon steel with clean internal metric coarse threads, these standard 6-sided hex nuts provide superior clamping power and mechanical grip when paired with hex head bolts, stud anchors, machine screws, and fully-threaded drop rods.
Featuring chamfered corners on both faces for smooth wrench engagement, each nut is coated in a bright electro-zinc passivated finish to resist atmospheric oxidation, humidity, and rust in interior and sheltered outdoor environments. Whether used for electrical strut channel fabrication, HVAC duct suspension, plumbing pipe clamping, or heavy timber joints, these full hex nuts are an indispensable fundamental fastener for every job site.
