S-91005A103 M8 Flange Nuts

Key Features & Benefits at a Glance

• Enhanced load distribution with 19mm flange diameter to prevent surface damage and maintain joint integrity under high stress
• Superior corrosion resistance from zinc-plated steel construction, extending service life in harsh industrial environments
• Reliable coarse thread engagement with 1.25mm pitch for faster assembly and vibration resistance in demanding applications
• Precision Class 6G thread fit ensuring consistent mating with standard bolts and reducing cross-threading risks
• Secure external hex drive allowing high torque application with common tools for robust fastening
• Compliance with RoHS 3 and REACH meeting strict environmental regulations for safe use across industries
• Durable 10mm height profile providing optimal strength-to-weight ratio for space-constrained assemblies

Professional Applications & Engineering Value

This M8 zinc-plated steel flange nut delivers critical engineering advantages where vibration loosening and corrosion are primary concerns. The integrated 19mm flange eliminates need for separate washers while distributing clamp force across wider surfaces - preventing material deformation in automotive chassis, machinery frames, and structural steelwork. The metric coarse thread (1.25mm pitch) maintains holding power in high-vibration environments while accelerating installation in production lines. Manufactured from zinc-plated steel, it provides sacrificial corrosion protection for outdoor equipment, agricultural machinery, and electrical enclosures exposed to moisture. The Class 6G thread tolerance ensures consistent performance with standard M8 bolts, reducing assembly errors and rework costs.

Specification Summary & Compliance

Precision-engineered with Class 6G thread fit per metric standards, featuring M8x1.25mm coarse threading with 13mm hex width and 10mm height. Flange dimensions maintain 19mm diameter with 2.5mm thickness for optimal bearing surface. Fully compliant with RoHS 3 (2015/863/EU) under exemption 6(a)-I and REACH (EC 1907/2006) regulations, ensuring environmental responsibility while maintaining mechanical performance through lead-alloyed steel construction.
