20-Pack 3/4" Split Lock Washers, 304 Stainless Steel Spring Lock Washers

Heavy-Duty 304 Stainless Steel Split Spring Lock Washers

Prevent fastener loosening due to vibration with our industrial-grade split spring lock washers. These washers act as a powerful mechanical spring, providing constant tension against the nut or bolt head to keep your hardware tight and secure. Ideal for high-vibration environments like engines, moving machinery, and heavy equipment.

Superior Locking Mechanism
The split design creates a spring-like tension that "bites" into the fastener and the mounting surface. This increased friction effectively prevents accidental loosening, ensuring the structural integrity of your most critical projects. Forged from 304 stainless steel, they provide the perfect balance of strength and durability.

Two Performance Finishes:
Natural Series: Features a clean, bright 18-8 stainless steel finish, perfect for marine and heavy-duty industrial applications.
Black Series: Features an advanced Electrophoresis coating. Unlike standard black oxide, our coating is highly resistant to scratches and salt-spray, making it the top choice for blackout automotive builds and outdoor hardware.

Reliable Security: Essential for automotive, motorcycle, and mechanical repairs. Trust our spring washers to provide the long-term vibration resistance your professional projects demand.
