Hillman 100 Pcs Split Lock Washers (3/8") | Zinc-Plated Steel Lock Washers for Bolts, Nuts & Screws | Vibration-Resistant Fastening Hardware for Wood, Metal, Construction & Repair

Product Description Hillman 3/8-inch zinc split lock washers are designed to help maintain secure fastening connections in applications where vibration or movement could cause bolts and nuts to loosen. These washers are commonly used in mechanical assemblies, construction projects, equipment installations, and repair applications. The split ring design creates tension when the washer is compressed between the bolt head or nut and the material surface. This tension allows the washer to grip both surfaces, helping prevent the fastener from loosening during use. Lock washers are frequently used as part of a complete fastening system alongside bolts and nuts of the same size. By maintaining consistent clamping pressure, they help improve the stability and durability of the fastening connection. Constructed from durable steel, these washers feature a zinc-plated finish that provides moderate resistance to rust and corrosion. This protective coating helps extend the lifespan of the washer in general-purpose indoor or light exterior environments. These lock washers are sized for use with 3/8-inch bolts and fasteners, making them suitable for a wide range of construction, mechanical, automotive, and maintenance applications. Packaged in a convenient C-Pak containing 100 washers, these fasteners are ideal for contractors, mechanics, builders, and DIY homeowners working on equipment repairs, structural assemblies, automotive maintenance, and general hardware fastening projects. From the Manufacturer 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.
