[10000 BULK] External Lock Washers 18/8 Stainless Black Oxide #10

External Lock Washers 18/8 Stainless Black Oxide #10 are precision-engineered fasteners designed to prevent loosening in vibrating or dynamic assemblies. Made from 18/8 stainless steel and finished with a durable black oxide coating, these washers combine corrosion resistance with a low-reflective, professional finish for exposed hardware.

Key Features

• Material: 18/8 stainless steel for exceptional strength and corrosion resistance
• Finish: Black oxide coating provides a dark, non-reflective surface
• Type: External lock washer with outer diameter teeth that grip the mating surface to resist loosening
• Size: #10
• Applications: Ideal for automotive, machinery, electrical, and outdoor assemblies where vibration resistance is required

How It Works

As you tighten a bolt or screw, the external teeth bite into the surface while the washer’s spring pressure helps prevent rotation. This combination reduces the risk of fastener loosening under dynamic loads and vibration.

Installation Tips

Ensure surfaces are clean and free of debris. Place the external lock washer between the bolt head or nut and the mating surface, then tighten to the recommended torque. Do not reuse damaged washers.

Ideal Applications

Use these washers in automotive, industrial machinery, electrical enclosures, outdoor equipment, and other assemblies where secure fastening is critical and a unobtrusive, dark finish is desirable.
