[4500 BULK] Medium Split Lock Washers Steel Zinc 5/16

Enhance fastener security with our Medium Split Lock Washers in a durable steel construction and zinc finish. Sized at 5/16 inch, these washers are designed to prevent loosening under vibration and load, delivering reliable performance in demanding assemblies.

Overview

These split lock washers provide a spring-like action that bite into the mating surfaces to resist turning. The zinc plating adds corrosion resistance, helping maintain a strong lock in both indoor and outdoor environments. The medium profile balances effective locking with space efficiency for a wide range of applications.

Key Features

• Size: 5/16 inch bolt diameter
• Material: Steel
• Finish: Zinc plating for corrosion resistance
• Type: Medium split lock washer
• Function: Provides vibration resistance and helps prevent fastener loosening

Applications

Ideal for automotive, machinery, electrical, plumbing, and other industrial assemblies where secure fastening is essential. Suitable for environments where corrosion resistance and reliable locking are important.

How to Use

Place the washer between the bolt head (or nut) and the mating surface, then tighten to the recommended torque. The split design creates tension that maintains a tight lock as vibrations occur.
