PATIKIL 304 Stainless Steel M16x32mm Conical Belleville 10 Pack

Description

Product Overview

The PATIKIL 304 stainless steel Belleville washers are engineered to deliver a reliable locking action for M16 fasteners across a broad range of demanding applications. Constructed from premium 304 stainless steel, each washer offers exceptional hardness, high tensile strength, and outstanding corrosion resistance, ensuring that the fastener retains its torque even under severe vibration and temperature fluctuations. The conical spring design creates a self‑locking mechanism that tightens under load, preventing loosening and providing a consistent clamping force throughout the product’s service life. With dimensions of 16 mm inner diameter, 32 mm outer diameter, and a thickness of 3.8 mm, these washers fit standard M16 bolts and nuts without the need for additional adapters or modifications. The pack includes ten precisely machined washers, each inspected for dimensional accuracy and surface finish, guaranteeing uniform performance from the first unit to the last.

Beyond the core mechanical benefits, the washers are designed with a knurled edge that enhances grip on the bolt head or nut, further reducing the risk of slippage during assembly or operation. The stainless‑steel composition also offers excellent resistance to rust, chemicals, and marine environments, making these washers suitable for outdoor, marine, and high‑humidity settings where traditional carbon‑steel lock washers would quickly degrade. The product complies with industry standards for metric lock washers, providing confidence to engineers and technicians who require certified components for safety‑critical assemblies. Whether used in automotive suspension systems, industrial machinery, or construction equipment, the PATIKIL Belleville washers deliver the durability and performance expected from a high‑grade fastener accessory.

Usage

These washers excel in applications where a secure, non‑rotating joint is essential. In automotive contexts, they are commonly installed on engine mounts, transmission housings, and suspension linkages to prevent bolt loosening caused by engine vibration and road shocks. Their conical spring action absorbs dynamic loads, maintaining clamping force and reducing wear on mating surfaces. In industrial machinery, the washers are employed on gearboxes, pump housings, and heavy‑duty frames where repetitive motion and torque fluctuations can otherwise lead to fastener fatigue. The stainless‑steel material ensures that the washers remain functional in environments exposed to oil, coolant, and cleaning agents, eliminating the need for frequent replacement.

Construction professionals also benefit from the robust locking capability of these washers. When assembling steel scaffolding, modular frames, or prefabricated building components, the washers provide a quick, tool‑free method to lock bolts in place, saving time on site while maintaining structural integrity. Their resistance to corrosion makes them ideal for outdoor projects where exposure to rain, humidity, and salt spray is inevitable. Additionally, the washers can be used in household applications such as securing heavy furniture, mounting brackets, or DIY projects that demand a reliable, long‑lasting fastening solution.

For maintenance technicians, the installation process is straightforward: verify that the bolt or nut size matches the washer’s M16 specification, position the washer with the knurled side facing the fastener, and tighten using a standard wrench or socket. The self‑locking nature of the Belleville design means that no additional locking mechanisms, such as thread‑locking compounds, are required, simplifying inventory and reducing overall assembly cost. The washers are also reusable in many cases, provided they have not been deformed during removal, offering an economical option for repeatable maintenance tasks.

FAQ

What size bolt or nut should I use with these washers?

The washers are specifically sized for M16 bolts and nuts. Ensure the bolt or nut has a 16 mm thread diameter so the washer’s inner diameter matches perfectly, providing optimal load distribution and locking performance.

Can these washers be reused after removal?

Yes, as long as the washer has not been permanently deformed during removal. Inspect the washer for any dents or loss of spring tension; if it remains flat and retains its conical shape, it can be safely reinstalled.

Are the washers suitable for marine applications?

Absolutely. The 304 stainless steel material offers superior resistance to saltwater corrosion, making these washers ideal for marine hardware, boat fittings, and coastal construction projects where exposure to seawater is common.

How do I install the washer to achieve the best locking effect?

First, confirm the bolt or nut size matches the M16 specification. Place the washer with the knurled side facing the fastener, then tighten the bolt or nut using a standard wrench or socket. The conical spring action will automatically generate a locking force as the fastener is torqued.

What is the difference between these washers and standard flat washers?

Standard flat washers provide a simple spacing function, whereas Belleville washers add a spring‑loaded locking capability. The conical shape of the PATIKIL washers creates a continuous tension that resists loosening, offering superior performance in high‑vibration and load‑critical applications.
