These washers are widely used in construction, mechanical assemblies, automotive repairs, equipment installations, and general maintenance projects. The split ring design creates tension when compressed under a bolt head or nut during tightening. This tension allows the washer to grip both the fastener and the material surface, helping reduce the risk of loosening caused by vibration or mechanical movement. Lock washers are typically used as part of a complete fastening system alongside compatible bolts and nuts. By maintaining pressure on the fastened components, they help ensure a more stable and secure mechanical connection over time. Manufactured from 18-8 stainless steel, these washers offer excellent durability and superior resistance to rust and corrosion compared to standard steel washers. The stainless steel construction makes them suitable for outdoor installations, moisture-prone environments, and applications where long-term corrosion resistance is important. These lock washers are designed for use with 3/8-inch bolts and fasteners, making them compatible with many common construction and mechanical hardware assemblies. Packaged in a convenient C-Pak containing 100 washers, these stainless steel fasteners are ideal for contractors, mechanics, builders, and DIY homeowners working on equipment repairs, structural installations, automotive maintenance, and general fastening projects requiring corrosion-resistant hardware.
This split lock washer provides a circular bearing surface with offset split ends which help bite into the mating material to provide a locking feature when tightened beneath a nut. It is round with a hole in the center and can be used where loosening from corrosion or vibration is a concern. Lock washers are commonly used in any application using a bolt where two pieces are being drawn together.
