M12 Nut Lock Washer for 12mm Bolts, Nut Locking, Wedge Locking Washer

M12 Nut Lock Washer – Wedge Locking Washer for Bolts & Nuts

Heavy-Duty Locking Solution for High-Vibration Applications

The Nut Lock Washer is a precision-engineered, two-piece wedge locking system designed to keep fasteners secure in environments exposed to heavy vibration, dynamic loads, or thermal cycling. Made for use with M12 bolts and nuts, it features interlocking serrated faces that create a wedge effect under tension—resisting loosening without the need for adhesives or locknuts.

Manufactured from hardened spring steel and finished with a zinc plating, this washer offers outstanding mechanical strength and long-lasting protection against corrosion.

Key Features:

• Wedge Locking Design: Serrated cam faces interlock and create a mechanical wedge effect, preventing fastener rotation even under extreme vibration.
• High-Grip Outer Faces: Aggressive surface texture bites into both the nut/bolt head and the joint surface to maintain clamp force.
• Tough Construction: Made from hardened spring steel to withstand high stress and load without deformation.
• Corrosion Resistant: Zinc plated finish provides protection in industrial and outdoor environments.
• Reusable Performance: Maintains locking ability through repeated tightening and loosening cycles.
• Easy to Use: Installs with standard tools—no special preparation or additional locking products required.

Specifications:

• Inner Diameter: 12.5 mm (for clearance with M12 fasteners)
• Outer Diameter: Approx. 21–25 mm
• Combined Thickness: ~3.0–3.5 mm
• Material: Hardened Spring Steel
• Finish: Zinc Plated

Applications:

• Construction and structural assemblies
• Heavy machinery and equipment
• Automotive and transportation systems
• Wind turbines and energy infrastructure
• Railways, marine, and aerospace fastenings
• Any high-load or high-vibration bolted joint

Built to perform where standard washers fail, the M12 Nut Lock Washer delivers superior resistance to loosening in the most demanding environments. Tough, reusable, and corrosion-resistant—it’s the smart choice for reliable fastening.
