Belleville Washers 304 Stainless Steel Conical Cup SVYARLYU 1/4″ 20pcs

Description

Product Overview

Our Belleville washers are precision‑engineered components designed to meet the rigorous demands of modern fastening systems. Constructed from high‑grade 304 stainless steel, each washer offers superior corrosion resistance, ensuring long‑term performance even in harsh environments such as marine applications, chemical processing plants, and outdoor installations. The conical disc spring cup design creates a self‑locking mechanism that maintains consistent tension across a wide range of temperatures and loads, reducing the risk of loosening due to vibration or thermal expansion.

Each washer measures 1/4″ in diameter with a 20‑piece quantity per pack, providing ample inventory for routine maintenance, bulk projects, or emergency repairs. The one‑sided embossing on the washer surface aids in proper orientation during installation, while the narrow, medium, and wide edge options accommodate a variety of bolt head styles and clearance requirements. The product dimensions are compact at 0.8 x 0.8 x 0.8 inches, weighing only 6.4 ounces, making storage and handling effortless.

Usage

These washers excel in a multitude of settings. In industrial machinery, they are used to preload bearings, secure gear assemblies, and stabilize shafts where precise torque control is essential. In the office or home workshop, they serve as reliable fasteners for furniture assembly, equipment mounting, and DIY projects that demand durability and repeatable performance. Their stainless‑steel composition makes them suitable for food‑processing equipment, medical devices, and any application where hygiene and resistance to rust are paramount.

Installation is straightforward: place the washer between the bolt head and the mating surface, then tighten to the specified torque. The conical shape automatically compensates for minor surface irregularities, distributing load evenly and preventing localized stress concentrations. Because the washers are designed to resist slipping, they remain securely in place even under cyclic loading, making them an ideal choice for vibration‑prone environments such as automotive suspensions, HVAC systems, and heavy‑duty conveyors.

FAQ

What size washers are included in the pack?

The pack contains 20 pieces of 1/4″ diameter washers. Each washer is available in narrow, medium, and wide edge variations to match different bolt head profiles.

Can these washers be used in high‑temperature applications?

Yes. 304 stainless steel retains its mechanical properties up to approximately 870°F (465°C), making the washers suitable for many high‑temperature environments.

How do I determine the correct washer thickness for my application?

Refer to the engineering specifications of your equipment. The conical design automatically adjusts to minor variations, but for critical loads, consult the load‑deflection chart provided by the manufacturer.

Are these washers compatible with stainless‑steel bolts?

Absolutely. Using stainless‑steel washers with stainless‑steel bolts prevents galvanic corrosion and maintains the integrity of the fastening system.

What is the lead time for bulk orders?

Standard inventory is shipped within 2‑3 business days. For larger bulk orders, we can arrange expedited production and shipping to meet your project timelines.
