316 Stainless Locking Washers

Nord-Lock 316 Stainless Steel Locking Washers provide reliable bolted-joint security in applications where corrosion resistance and resistance to vibration are important. Manufactured from 316 stainless steel, these wedge-locking washers use tension rather than friction to help prevent bolts from loosening under vibration and dynamic loads. Their corrosion-resistant construction makes them well suited for demanding environments, including marine, chemical processing, food processing, and other applications where stainless steel fastening components are preferred.

Overview

Reliable Wedge-Locking Technology

Nord-Lock 316 Stainless Steel Locking Washers are designed to help secure bolted joints against loosening caused by vibration and dynamic loads. The Nord-Lock wedge-locking principle uses tension to lock the joint rather than relying solely on friction, helping maintain bolt preload during demanding operating conditions.

316 Stainless Steel Construction

Manufactured from 316 stainless steel, these locking washers provide excellent corrosion resistance for applications where environmental exposure is a concern. The stainless steel construction makes them particularly suitable for equipment and assemblies exposed to moisture, marine environments, chemicals, and other corrosive conditions.

Designed for Demanding Applications

Nord-Lock 316 Stainless Steel Locking Washers combine corrosion-resistant materials with engineered mechanical locking performance. They are suited to applications where maintaining a secure bolted connection is important and where standard carbon steel locking hardware may not provide the desired level of corrosion resistance.

Consistent Installation

The washers are supplied as pre-assembled pairs, helping simplify handling and installation. Each washer pair is installed beneath the bolt head or nut, with the wedge-locking surfaces positioned against one another. This design provides a straightforward method for securing threaded connections while supporting consistent joint performance.

Suitable for Corrosive Environments

The use of 316 stainless steel makes these washers a practical choice for applications requiring corrosion-resistant fastening hardware. Common environments include marine and offshore equipment, chemical processing systems, food and beverage equipment, water and wastewater applications, and other industrial installations where exposure to moisture or corrosive substances is possible.

Nord-Lock Engineered Joint Security

Nord-Lock locking washers are engineered specifically for bolted-joint security under vibration and dynamic loading. The 316 stainless steel series extends this wedge-locking approach to applications where corrosion resistance is an important part of fastening-system selection.

Applications

Nord-Lock 316 Stainless Steel Locking Washers are suitable for a wide range of industrial and commercial fastening applications, including marine equipment, offshore installations, chemical processing machinery, food processing equipment, water treatment systems, manufacturing machinery, pumps, valves, and other assemblies requiring corrosion-resistant bolted-joint security.
