Seachoice RP-SC1446 Stainless Steel External Tooth Lock Washer - 1/4 Inch

The Seachoice RP-SC1446 is a 1/4-inch external tooth lock washer constructed from 410 stainless steel for corrosion resistance in marine and outdoor applications. External tooth lock washers feature teeth on the outer perimeter that bite into both the fastener head and the mounting surface, providing superior resistance to loosening from vibration and thermal expansion.

Key Features:

• 1/4-inch nominal size for use with standard 1/4-inch bolts and screws
• 410 stainless steel construction offers good corrosion resistance and durability
• External teeth design grips both fastener and work surface
• Ideal for marine, automotive, and industrial applications
• Sold in bulk packs of 100 washers

These lock washers are essential hardware for securing fasteners in environments where vibration, moisture, or temperature changes could cause standard fasteners to loosen over time. The 410 stainless steel material provides a balance of strength and corrosion resistance, making them suitable for both freshwater and light-duty saltwater applications.
