[7500 BULK] Medium Split Lock Washers Steel Plain 3/8

Medium Split Lock Washers in steel with a plain finish are a reliable fastening solution designed to prevent loosening in vibrating mechanical assemblies. Sized for 3/8 fasteners, these washers provide a spring-like locking action that helps maintain proper clamping force over time.

Overview

Perfect for machinery, automotive components, and general equipment applications, these steel plain split lock washers act as a vibration-resistant gap filler that bites into both surfaces when tightened, increasing friction and reducing the risk of bolt loosening.

Key Features

• Material: Steel for strength and durability
• Finish: Plain (uncoated) for versatile use
• Size: 3/8 inch (fits 3/8 in fasteners)
• Locking Action: Spring-like split to resist loosening under vibration
• Applications: Ideal for mechanical assemblies where vibration or dynamic loads are present

Specifications

• Type: Split lock washer
• Diameter/Size: 3/8 in (bolt size)

To install, place the washer under the nut or bolt head and tighten. The split edge will bite into the mating surfaces, increasing friction and helping maintain a secure, stable connection even in challenging conditions.
