Locking washers

Locking washers are compact, high‑impact hardware solutions designed to keep fasteners from loosening under vibration, shock, and dynamic loads. Our Locking Washers deliver consistent clamping force across a variety of environments, making them an essential upgrade for any project that demands reliability, from DIY repairs to heavy machinery maintenance.

Why choose locking washers

Enhanced vibration resistance: The primary job of a locking washer is to resist rotational movement that can cause bolts to back out. By creating a spring-like tension or a serrated bite into the mating surfaces, these washers maintain preload and minimize loosening over time.

Versatile designs for different needs: Whether you’re dealing with light household fixtures or rugged industrial assemblies, there are locking washer styles to match your application—split (spring) washers for general vibration, serrated/teeth washers for aggressive locking on uneven surfaces, and wave or Belleville-inspired varieties for specific preload characteristics.

Key features and benefits

• Material options for durability and corrosion resistance: Choose from stainless steel for moisture-prone environments, or zinc/plated carbon steel for cost-effective, everyday use.
• Size compatibility: Available in a range of inner diameters to fit standard bolt sizes, plus varying outer diameters and thicknesses to balance lock strength with clearance needs.
• Consistent performance: Engineered to maintain clamping force through repeated cycles, temperature changes, and higher-than-average vibration conditions.
• Easy integration: Simple to retrofit into existing assemblies; no special tools required beyond standard wrenches or drivers.

Use cases

• Automotive and motorcycle components where engines and exhaust systems generate constant vibration.
• Machinery and equipment mounts, conveyors, and power tools that experience dynamic loads.
• Furniture and cabinetry assemblies where seasonal expansion and movement can loosen fasteners.
• Electronics enclosures and control panels that require secure, vibration‑resistant mounting.

How to select and install

• Match the bolt and washer: Choose a washer with an inner diameter that fits your bolt shank snugly, and select a material that resists the anticipated exposure (moisture, chemicals, or temperature).
• Consider the locking mechanism: For light to moderate vibration, a serrated or split washer provides reliable bite and tension. In high‑vibration environments, a wave or heavier gauge option can offer greater preload stability.
• Surface preparation: Ensure mating surfaces are clean, flat, and free of debris to maximize the washer’s contact and locking action.
• Torque and seating: Tighten to your fastener’s recommended torque, then recheck after equipment has cooled or run for a short period. Avoid over‑tightening, which can crush or deform the washer and reduce its effectiveness.

Care and maintenance

• Inspect locking washers during routine maintenance for signs of deformation, corrosion, or wear.
• Replace if the locking engagement appears compromised or after significant impact or vibration cycles.
• Store in a dry environment to preserve corrosion resistance, especially for stainless steel variants.

Whether you’re assembling a bike, repairing a lawn tractor, or outfitting a machine shop, our Locking Washers provide dependable, long‑lasting security for your fasteners. They’re a simple, pragmatic upgrade that yields real peace of mind—helping you avoid downtime, rework, and loose fittings. Ready to lock things in place with confidence?
