[2000 BULK] Lock Washers Internal Tooth Steel Zinc 3/4

Lock Washers Internal Tooth Steel Zinc 3/4 are precision-engineered fastener accessories designed to resist loosening in high-vibration environments. Made from durable steel with a zinc finish, these internal-tooth lock washers bite into the mating surface to maintain a secure clamp between bolt and nut, even under dynamic loads.

Key features

• Material: Steel with zinc plating for corrosion resistance
• Design: Internal teeth grip the mating surface to prevent loosening
• Size: 3/4 inch nominal diameter
• Applications: Suitable for automotive, machinery, electrical, and general hardware assemblies
• Benefits: Enhanced vibration resistance and sustained clamping force

Why choose internal tooth lock washers?

Internal-tooth lock washers are ideal when you need a secure lock without protruding teeth. The internal teeth engage with the bolt head or nut, while the flat outer edge provides a flush, smooth surface for mating parts. Zinc finish adds durable corrosion protection for long-lasting performance in tough environments.

Common uses

Use in mechanical assemblies, automotive maintenance, equipment installations, and any project requiring a reliable anti-loosening solution for threaded fasteners.
