PATIKIL M10x22x1.5mm Washers 100pcs Zinc Belleville Spring Disc

Description

Product Overview

Introducing the PATIKIL M10x22x1.5mm flat Belleville spring disc washers, a precision‑engineered fastener designed to meet the rigorous demands of automotive, industrial, and construction applications. Each washer is fabricated from high‑strength 65 manganese (65Mn) steel, a material renowned for its exceptional tensile strength, toughness, and wear resistance. The washers are then coated with a white zinc plating that provides superior corrosion resistance, extending the service life even in harsh, moisture‑laden environments. The conical, knurled design of the disc creates a spring‑like action that maintains a consistent clamping force, preventing bolt or nut loosening caused by vibration, thermal expansion, or dynamic loads. Packaged in a compact 100‑piece box, the washers measure 10 mm × 22 mm × 1.5 mm (ID × OD × T), offering a perfect fit for standard M10 hardware while delivering a reliable, reusable locking mechanism.

Usage

These Belleville washers excel in a wide range of real‑world scenarios where secure fastening is critical. In automotive assemblies, they are used to lock engine bolts, suspension components, and transmission mounts, ensuring that vibrations from the road do not compromise joint integrity. In industrial machinery, the washers provide a dependable solution for securing gear shafts, pump housings, and heavy‑duty brackets, where repeated cycling can otherwise lead to loosening. Construction professionals rely on the washers for anchoring steel frames, securing roofing fasteners, and reinforcing concrete‑to‑steel connections, benefiting from the washer’s ability to absorb shock and maintain tension over long periods. The white zinc coating also makes the washers suitable for outdoor applications such as marine equipment, agricultural machinery, and storage racks, where exposure to salt spray or chemicals could otherwise cause rapid corrosion.

Why Choose Us

Choosing PATIKIL means selecting a brand committed to quality, consistency, and customer satisfaction. Our manufacturing process adheres to strict ISO‑9001 standards, guaranteeing that each washer meets exact dimensional tolerances and material specifications. The 65Mn steel core is heat‑treated to achieve a hardness that balances flexibility with load‑bearing capacity, allowing the washer to compress under torque and then rebound to its original shape, preserving the preload on the fastened joint. The white zinc plating is applied using a controlled electro‑galvanizing process that ensures uniform coverage and adhesion, protecting the steel from rust and oxidation without compromising the washer’s spring characteristics. Additionally, each batch undergoes rigorous testing for tensile strength, fatigue life, and corrosion resistance, providing confidence that the product will perform reliably in demanding environments. Our responsive customer support team is available to answer technical questions, assist with order specifications, and provide after‑sales guidance, reinforcing our dedication to a seamless purchasing experience.

FAQ

What size washers are included in the package?

The package contains 100 flat Belleville washers, each sized at M10 × 22 mm × 1.5 mm (ID × OD × Thickness), suitable for standard M10 bolts and nuts.

Can these washers be used in high‑temperature environments?

Yes. The 65Mn steel retains its mechanical properties up to approximately 300 °C (572 °F). However, prolonged exposure to temperatures above this range may affect the zinc coating, so additional heat‑resistant coatings should be considered for extreme applications.

How does the white zinc coating affect the washer’s performance?

The white zinc coating provides a protective barrier against moisture and chemicals, reducing the risk of rust without interfering with the washer’s spring action. It also adds a slight aesthetic benefit, making the washers easier to identify during assembly.

Are these washers reusable after being compressed?

Absolutely. Belleville washers are designed to be compressed and then rebound to their original shape, allowing multiple cycles of installation and removal without loss of performance, provided they are not damaged or excessively deformed.

What is the recommended torque setting for using these washers?

Torque values depend on the specific application and bolt grade. As a general guideline, for an M10 bolt with a standard grade 8.8, a torque of 45–55 Nm (33–40 lb‑ft) is appropriate when using a Belleville washer to achieve the desired preload.
