Wedge Locking Washer NordLock Carbon Steel M11 Zinc Coated 10 Pair

Description

Product Overview

The Nord-Lock wedge locking washer is a specialized fastener component designed to eliminate loosening in high‑vibration environments. Constructed from high‑grade carbon steel, each washer receives a zinc flake coating that provides superior corrosion resistance while maintaining the strength required for demanding industrial applications. The M11 size matches a wide range of bolt diameters, making it a versatile choice for engineers, maintenance technicians, and assembly line workers who need reliable torque retention.

Each pack contains ten identical washers, carefully inspected for dimensional accuracy and surface finish. The wedge design creates a self‑locking action when the washer is compressed between the bolt head and the mating surface, converting axial load into a radial clamping force. This mechanism distributes stress evenly across the joint, reducing the risk of fatigue failure and extending the service life of the entire assembly. The product complies with Nord-Lock’s rigorous quality standards, ensuring consistency from batch to batch.

Beyond its mechanical advantages, the washer’s compact dimensions—0.73 x 0.1 x 0.45 inches—allow it to fit into tight spaces without compromising performance. The lightweight nature (1.16 ounces per pack) simplifies inventory handling and reduces shipping costs for bulk orders. Whether used in automotive chassis, industrial machinery, or construction equipment, the washer delivers predictable, repeatable results that meet or exceed industry specifications.

Nord-Lock’s reputation for engineering excellence is reflected in the meticulous manufacturing process. Each washer undergoes heat treatment to achieve optimal hardness, followed by a controlled zinc flake coating application that adheres uniformly to the steel substrate. This dual‑process approach guarantees that the washers maintain their structural integrity even when exposed to harsh chemicals, moisture, and temperature fluctuations common in outdoor and factory settings.

Usage

These wedge locking washers are ideal for applications where vibration, shock, and cyclic loading are prevalent. In automotive manufacturing, they secure engine mounts, transmission housings, and suspension components, preventing bolt back‑out that could lead to costly downtime. In the aerospace sector, the washers are employed on wing brackets and landing gear assemblies, where weight savings and reliability are paramount.

Industrial users find the washers indispensable for machinery maintenance, such as locking bolts on conveyor rollers, gearboxes, and pump housings. The washers also excel in construction equipment, securing structural steel connections on cranes, excavators, and bulldozers. Their ability to maintain preload under dynamic loads makes them a preferred choice for safety‑critical installations.

Installation is straightforward: place the washer between the bolt head and the mating surface, tighten the bolt to the specified torque, and the wedge action will automatically engage. No additional hardware or special tools are required, which streamlines assembly time and reduces labor costs. The washers are compatible with standard torque wrenches and can be used alongside other Nord-Lock products for comprehensive joint protection.

FAQ

What makes the wedge locking washer different from a standard lock washer?

The wedge locking washer uses a tapered wedge that converts axial load into a radial clamping force, creating a permanent lock that a standard lock washer cannot achieve. This design prevents loosening caused by vibration, shock, and thermal expansion.

Can these washers be used with stainless steel bolts?

Yes, the washers are compatible with stainless steel bolts. The zinc flake coating provides a protective barrier that prevents galvanic corrosion when paired with stainless steel fasteners, making them suitable for mixed‑material assemblies.

What torque specifications should I follow when installing the washer?

Follow the torque recommendations provided by the bolt or equipment manufacturer. The wedge locking action engages automatically once the bolt reaches the specified torque, so no additional torque adjustments are needed beyond the standard value.

Are the washers reusable after removal?

While the washers can be reinstalled, it is recommended to inspect them for any signs of wear or deformation. For critical applications, replacing the washer with a new unit ensures the highest level of joint security.

How do I store the washers to maintain their performance?

Store the washers in a dry, temperature‑controlled environment, preferably in their original packaging. Avoid exposure to extreme humidity or corrosive chemicals, which could compromise the zinc coating over time.

These comprehensive details provide a clear understanding of the Nord-Lock wedge locking washer’s capabilities, ensuring that engineers, procurement specialists, and maintenance professionals can make informed decisions when selecting fastener solutions for demanding applications.
