[5 PKG] Heavy Hex Lock Nuts NTU Nylon Inserts Thin Height Steel Zinc 1-3/4-5

Heavy Hex Lock Nuts NTU Nylon Inserts Thin Height Steel Zinc 1-3/4-5 are engineered for secure, vibration-resistant fastening in a compact footprint. Crafted from strong steel with a durable zinc finish, these nuts combine a heavy hex shape with a nylon insert to provide locking action that resists loosening under dynamic loads. Size 1-3/4-5 ensures compatibility with standard hardware kits while enabling tighter, cleaner assemblies.

Product Highlights

• NTU nylon insert lock nuts with self-locking nylon insert create friction that resists loosening from vibration and shock.
• Thin height design for spaces where standard nuts won't fit, enabling more compact assemblies.
• Material: steel with zinc plating for corrosion resistance and long service life.
• Heavy hex nut provides better grip and torque tolerance for high-strength applications.
• Size: 1-3/4-5 thread specification for compatible fasteners.

Applications

Use in machinery, automotive, and structural assemblies where vibration or dynamic forces may loosen standard nuts. The NTU nylon insert achieves reliable locking without external locking devices.

Installation and Care

Hand-tighten, then tighten with a wrench to the recommended torque. Check fit periodically in harsh environments and replace if threads show wear. Store in a dry environment to prevent corrosion.
