Wedge Locking Washer, Carbon Steel, Zinc Flake Coated, M12, 200 Pack

Description

Product Overview

The NordLock wedge locking washer is engineered to meet the demanding requirements of modern industrial assembly. Constructed from high‑grade carbon steel, each washer is treated with a zinc‑flake coating that provides superior resistance to moisture, chemicals, and temperature fluctuations. This dual‑layer protection ensures long‑term durability, even in harsh environments such as chemical processing plants, automotive manufacturing lines, and heavy‑duty machinery.

Designed specifically for M12 fasteners, the washer features a precision‑engineered wedge mechanism that creates a self‑locking action when the bolt is tightened. This action converts axial tension into a radial clamping force, eliminating the common issue of bolt loosening caused by vibration or dynamic loads. The result is a reliable, repeatable torque‑to‑clamp conversion that maintains joint integrity over the life of the equipment.

Each package contains 200 washers, providing a cost‑effective solution for large‑scale projects, routine maintenance, or inventory stocking. The washers are supplied in a compact, recyclable packaging that protects the components from damage during shipping and handling. With NordLock’s reputation for quality and precision engineering, you can trust that every washer meets stringent industry standards and performance specifications.

Key dimensions include a standard inner diameter compatible with M12 bolts, a thickness optimized for load distribution, and a flat outer surface that ensures even contact with mating parts. The product dimensions listed in the manufacturer’s data sheet are 3.25 × 2.75 × 3.31 inches, weighing approximately 1.28 pounds per pack, making it easy to handle and store.

Usage

These wedge locking washers excel in applications where vibration, shock, and cyclic loading are prevalent. Typical use cases include securing motor housings, gearboxes, pump assemblies, and structural frames in heavy‑duty equipment. The self‑locking feature eliminates the need for additional locking mechanisms such as lock nuts or thread‑locking compounds, simplifying assembly processes and reducing overall part count.

Installation is straightforward: place the washer between the bolt head and the mating surface, then torque the bolt to the recommended value. As the bolt is tightened, the wedge action engages, creating a secure lock that resists loosening. This makes the washers ideal for maintenance crews who require quick, reliable fastening solutions without the need for specialized tools.

Because of their corrosion‑resistant coating, the washers are suitable for outdoor installations, marine environments, and facilities with high humidity or exposure to corrosive agents. They also perform well in high‑temperature settings, maintaining structural integrity up to the limits of the carbon‑steel substrate.

FAQ

What size fasteners are compatible with these washers?

The washers are specifically sized for M12 bolts and nuts, matching the standard inner diameter required for a secure fit.

Can these washers be used in corrosive environments?

Yes. The zinc‑flake coating provides excellent protection against moisture, chemicals, and salt spray, making the washers suitable for marine, outdoor, and industrial settings.

Do I need any special tools to install the wedge locking washers?

No special tools are required. Install the washer between the bolt head and the mating surface, then torque the bolt to the specified value using a standard torque wrench.

How does the wedge locking mechanism work?

When the bolt is tightened, the wedge shape forces the washer to expand radially, creating a locking action that converts axial tension into a clamping force, preventing the bolt from loosening.

What warranty does NordLock offer on these washers?

NordLock provides a limited one‑year warranty covering material defects and manufacturing errors, backed by responsive technical support and replacement services.
