Professional Applications & Engineering Value
Engineered for industrial machinery and equipment assembly, this M4 square nut delivers critical vibration resistance where conventional fasteners fail. The black zinc-plated steel construction provides corrosion protection in manufacturing environments exposed to moisture and chemicals. Its metric coarse thread (0.7mm pitch) enables rapid installation in structural frameworks and conveyor systems, while the external square drive allows secure tightening in confined spaces. The Class 7H thread fit ensures precise engagement with mating components, preventing loosening under continuous operation. This DIN 557 compliant fastener solves common maintenance challenges by combining durability with standardized dimensions for replacement simplicity.
Specification Summary & Compliance
This metric square nut features M4 x 0.7mm coarse thread with right-hand direction and Class 7H thread fit tolerance. Manufactured to DIN 557 standards with Class 5 strength rating, it maintains dimensional accuracy across 7mm width and 3mm height specifications. The black zinc-plated steel construction meets industrial corrosion protection requirements while complying with RoHS and REACH environmental directives for safe usage in regulated applications.
