Professional Applications & Engineering Value

This heavy-duty M56 locknut addresses critical safety concerns in high-vibration industrial environments where conventional fasteners frequently fail. The cotter pin locking mechanism provides absolute mechanical security, making it ideal for rotating machinery, structural connections, and heavy equipment where vibration-induced loosening could lead to catastrophic failure. Engineered with Class 8 strength steel and coarse metric threading, this DIN 935 compliant nut maintains integrity under extreme loads while the external hex drive facilitates installation in confined spaces. The combination of 85mm width and 57mm height provides optimal bearing surface for distributed load transfer, while the precise Class 6H thread fit ensures consistent performance across industrial applications including construction machinery, agricultural equipment, and transportation systems.

Specification Summary & Compliance

This metric locknut features M56 x 5.5mm coarse threads with Class 6H thread fit tolerance, manufactured to DIN 935 specifications for dimensional accuracy and performance reliability. The nut meets Class 8 strength requirements and includes standardized cotter pin provisions with 8mm pin diameter, 12mm minimum slot depth, and 9mm slot width. Compliance with RoHS 3 (2015/863/EU) ensures environmental safety standards are maintained for industrial applications worldwide.
