Stainless Steel Split Lock Washers

The Stainless Steel Split Lock Washers are designed to provide a simple yet effective solution for securing nuts and bolts in various applications. These lock washers are made from high-quality 304 stainless steel, ensuring exceptional durability and corrosion resistance.

The split design of these washers is their defining feature. With a ring split at one point and bent into a helical shape, they effectively grab onto the threads of the bolt, providing a strong grip and preventing self-loosening.

These lock washers find great utility in a range of applications, including boat lifts, boat hoists, cable installations, and cradle rigging. Their reliability in securing fasteners makes them an essential component for maintaining the safety and stability of such equipment.

In terms of compatibility, these lock washers are suitable for use with treated lumber, ensuring secure fastening even in harsh environments. They conform to industry standards, meeting the requirements of ASME B18.21.1, DIN 127 B, and the United States Military Standard NASM 35338 (formerly known as MS 35338 and AN-935).

Installing the Stainless Steel Split Lock Washers is straightforward. They are designed to be tightened in a right-hand direction (clockwise), providing resistance to rotation. However, it is important to note that they are not effective on left-hand threads or hardened surfaces.

To maximize their performance, it is recommended not to use a flat washer beneath the spring lock washer, as this isolates the spring washer from biting into the component and resisting turning.

The trapezoidal shape of these lock washers provides an added benefit. When compressed near the proof strength of the bolt, they twist and flatten, reducing the spring rate of the joint. This feature helps maintain more force and prevents loosening, ensuring long-term reliability.

The Stainless Steel Split ock washers offer a reliable, durable, and easy-to-install solution for securing nuts and bolts. With their high-quality stainless steel construction, split design for enhanced grip, and compliance with industry standards, these lock washers provide the necessary resistance to rotation, preventing self-loosening and ensuring a secure connection in a wide range of applications.
