M8 Belleville Washers 100pcs Conical Disc Spring 18-8 Stainless Steel

Description

Product Overview

The M8 Belleville washers offered by TESILANG are precision‑engineered fasteners designed to provide a reliable, repeatable preload in a compact form factor. Each washer measures 0.2 x 0.2 x 0.15 inches and conforms to the DIN6796 standard, identified by the model number 304 Butterfly Washer. Constructed from 18‑8 stainless steel, these washers combine excellent corrosion resistance with high tensile strength, ensuring long‑term durability even in harsh industrial environments. The conical disc spring design creates a spring‑like action that compensates for thermal expansion, vibration, and dynamic loads, making them ideal for applications where consistent torque is critical. Packaged in a 100‑piece bulk quantity, the washers are ready for immediate deployment in assembly lines, maintenance kits, or repair inventories. The product is listed under the Industrial & Scientific category, specifically within Fasteners > Washers > Belleville Washers, and holds a competitive ranking among similar items.

Usage

These M8 Belleville washers are suited for a wide range of industrial and mechanical applications. They excel in machinery assembly where precise torque control is required, such as in gearboxes, motor mounts, and pump housings. The stainless‑steel construction makes them appropriate for marine equipment, food‑processing machinery, and chemical processing plants where exposure to moisture or corrosive substances is common. Additionally, the conical spring action helps mitigate vibration in automotive suspension components, aerospace brackets, and heavy‑duty construction tools. Maintenance technicians often use these washers for bolt tensioning, flange sealing, and as spacers in calibration rigs. Their compact size allows for easy insertion into tight spaces, and the 100‑piece pack ensures that spare parts are readily available for routine service intervals or unexpected repairs.

FAQ

What is the difference between a Belleville washer and a regular flat washer?

A Belleville washer has a conical shape that creates a spring‑like action, allowing it to maintain tension under varying loads, whereas a flat washer provides only a bearing surface and does not compensate for dynamic forces.

Can these washers be used with stainless steel bolts?

Yes, the 18‑8 stainless steel composition of the washers is compatible with stainless steel bolts, preventing galvanic corrosion and ensuring a uniform material response.

What torque specifications should I follow when installing M8 Belleville washers?

Torque values depend on the bolt grade and application; however, a typical range for M8 bolts with these washers is 8‑12 Nm. Always refer to the equipment manufacturer’s guidelines for precise requirements.

Are the washers reusable after removal?

While they can be reused if they have not been deformed or damaged, it is recommended to inspect each washer for permanent deformation before re‑installation to maintain proper preload.

How do I store the washers to preserve their performance?

Store them in a dry, temperature‑controlled environment, preferably in their original sealed packaging, to protect against moisture and contaminants that could affect the stainless‑steel surface.
