[10000 BULK] Lock Washers Internal Tooth Steel Zinc Yellow #1/4

Lock Washers Internal Tooth Steel Zinc Yellow #1/4 are precision-engineered fasteners designed to secure connections in a wide range of projects. Crafted from durable steel with a yellow zinc finish, these internal tooth lock washers bite into the mating surface to create a tight, vibration-resistant seal. Sized for #1/4 inch bolts, they deliver reliable performance in automotive, machinery, electrical, and general hardware applications.

• Material: Steel for strength and long-lasting durability.
• Finish: Yellow zinc plating provides corrosion resistance and a protective coating.
• Type: Internal tooth lock washer for added locking action under vibration.
• Size: #1/4 (fits bolts with a 1/4 inch diameter).
• Applications: Ideal for automotive, industrial machinery, electrical panels, and general fastener assemblies.

To install, place the washer between the bolt head and surface and tighten to the required torque. The internal teeth grip the surface to prevent loosening from vibration or thermal cycling. For best results, pair with compatible bolt material and mating surfaces.
