S-93760A123 M42 DIN 935 Locknuts

Key Features & Benefits at a Glance

• Superior vibration resistance with a reliable cotter pin locking mechanism that prevents loosening under extreme dynamic loads
• Exceptional load-bearing capacity thanks to the high-strength Class 8 steel construction for heavy-duty applications
• Precise metric coarse threading (M42x4.5mm) ensures quick installation and optimal engagement in demanding environments
• Industry-standard DIN 935 compliance guarantees dimensional accuracy and interchangeability with existing systems
• Robust external hex design (65mm) provides superior torque transmission and tool accessibility
• Enhanced safety and environmental compliance with RoHS 3 certification for industrial use
• Optimized slot dimensions (9mm width, 12mm depth) accommodate standard 8mm cotter pins for secure locking

Professional Applications & Engineering Value

This heavy-duty M42 locknut delivers critical security in high-vibration environments where standard fasteners fail. Engineered with Class 8 strength steel and metric coarse threading, it maintains clamp force in construction machinery, agricultural equipment, and structural assemblies. The cotter pin locking system provides positive mechanical locking that withstands shock loads and continuous vibration, eliminating the need for frequent retightening. With DIN 935 compliance and external hex drive, it offers perfect compatibility with industrial tooling while the RoHS 3 compliant material ensures environmental responsibility in manufacturing operations.
