10/20pcs M8 M10 M12 M16 M20 Washer Lock Washers Genuine Wedge Lock Washers Wedge Lock(10pcs M16)

Description

Product Overview

Our genuine wedge lock washers, manufactured by jiuxinyun, are engineered to meet the rigorous demands of industrial, automotive, and construction sectors. Each washer is crafted from high‑grade copper, offering excellent conductivity, corrosion resistance, and long‑term durability. The set includes ten pieces covering a comprehensive range of sizes—M8, M10, M12, M16, and M20—each precisely dimensioned to provide optimal fit and performance. The wedge design creates a self‑locking action when the bolt is tightened, converting axial tension into radial pressure that prevents loosening under vibration or dynamic loads. With a package dimension of 1.18 x 0.79 x 0.39 inches and a lightweight of 1.76 ounces, the set is compact yet robust, making it easy to store, transport, and deploy on site. Detailed specifications such as inner diameter, outer diameter, and thickness are meticulously calibrated: NL8 (M8) 8.7 mm × 13.5 mm × 2.5 mm, NL10 (M10) 10.7 mm × 16.6 mm × 2.5 mm, NL12 (M12) 13.0 mm × 19.5 mm × 2.5 mm, NL16 (M16) 17.0 mm × 25.4 mm × 3.4 mm, and NL20 (M20) 21.4 mm × 30.7 mm × 3.4 mm. These dimensions ensure a secure, interference‑fit that maximizes clamping force while minimizing the risk of material fatigue. The product’s best‑seller rank of #51 in the Wedge Lock Washers category underscores its popularity among professionals who demand reliability and precision. Designed for unisex adult use, the washers are suitable for a wide array of assemblies, from heavy‑duty machinery to delicate electronic housings, delivering consistent performance across diverse applications.

Usage

These wedge lock washers excel in environments where vibration, thermal cycling, and mechanical stress are prevalent. In automotive assemblies, they secure engine brackets, suspension components, and transmission mounts, ensuring that critical fasteners remain tight throughout the vehicle’s lifespan. In industrial machinery, they are employed on gearboxes, pump housings, and conveyor systems, where continuous operation can cause conventional washers to loosen over time. Construction professionals rely on these washers for structural steel connections, scaffolding joints, and prefabricated panel installations, where safety and stability are paramount. The copper composition also offers excellent electrical conductivity, making the washers ideal for grounding applications, electrical panels, and motor windings. Their corrosion‑resistant properties allow use in marine environments, outdoor installations, and chemical processing plants without degradation. Installation is straightforward: place the washer between the bolt head and the mating surface, tighten to the recommended torque, and the wedge mechanism will automatically lock the assembly, eliminating the need for additional locking devices. This simplicity reduces installation time, lowers inventory costs, and enhances overall project efficiency.

FAQ

What material are these washers made from?

The washers are fabricated from high‑quality copper, which provides excellent corrosion resistance, electrical conductivity, and durability, making them suitable for both mechanical and electrical fastening applications.

Can these washers be used with stainless steel bolts?

Yes, the wedge lock washers are compatible with stainless steel bolts as well as other common bolt materials. The copper washer’s softness allows it to conform to the bolt head, creating a secure lock without damaging the bolt surface.

How do I determine the correct washer size for my bolt?

Refer to the product specifications: NL8 fits M8 bolts (8.7 mm × 13.5 mm × 2.5 mm), NL10 fits M10 bolts (10.7 mm × 16.6 mm × 2.5 mm), NL12 fits M12 bolts (13.0 mm × 19.5 mm × 2.5 mm), NL16 fits M16 bolts (17.0 mm × 25.4 mm × 3.4 mm), and NL20 fits M20 bolts (21.4 mm × 30.7 mm × 3.4 mm). Choose the washer whose inner diameter matches the bolt’s nominal diameter for optimal performance.

Are these washers suitable for high‑temperature environments?

Copper maintains its mechanical properties at elevated temperatures, making these washers appropriate for many high‑heat applications. However, for extreme temperatures exceeding 200 °C, it is advisable to verify compatibility with your specific system requirements.

What is the recommended torque for installing these washers?

While torque values can vary based on bolt grade and application, a general guideline is to tighten the bolt to the manufacturer’s recommended torque for the specific bolt size, then add an additional 10‑15 % to ensure the wedge lock mechanism engages fully. Always consult the equipment’s technical documentation for precise torque specifications.
