Value Collection NLI20750NTU-010B Hex Jam Lock Nut 3/4-10

Product Description

The VALUE COLLECTION NLI20750NTU-010B is a hex jam lock nut with a nylon insert locking mechanism, sized for 3/4-10 UNC threads. It is manufactured from Grade 2 steel with a zinc finish for basic corrosion resistance. Standing 45/64 inches high with a 1-1/4 inch width across flats, this low-profile nut is designed to resist loosening caused by vibration or dynamic loads without requiring secondary locking hardware. The right-hand thread direction follows standard UNC fastener convention. Machinists, maintenance technicians, assembly workers, and general tradespeople install this style of nut across a wide range of structural and mechanical applications.

This jam lock nut is suited for use in light to medium structural assemblies, mechanical equipment, and maintenance applications where preventing fastener back-out is a priority. The nylon insert engages the mating thread to create prevailing torque, keeping the nut secured under vibration or cyclic loading. It is appropriate for indoor and light-duty outdoor installations where the zinc finish provides adequate protection. This nut is not intended for high-temperature environments where nylon insert integrity may be compromised.

Key Features

• Nylon insert locking style provides prevailing torque without additional locking hardware
• 3/4-10 UNC thread size with right-hand thread direction
• Grade 2 steel construction for general-purpose fastening applications
• Zinc finish offers basic corrosion resistance for typical indoor or sheltered use
• Low-profile jam nut height of 45/64 inches suits space-constrained assemblies
• 1-1/4 inch width across flats fits standard 1-1/4 inch hex wrench or socket

Compatibility

Designed as an OEM-style replacement or general-use nylon insert hex jam lock nut for assemblies using 3/4-10 UNC right-hand threaded fasteners in Grade 2 steel applications.

Installation Notes

Install using a standard 1-1/4 inch open-end wrench or socket. Ensure the mating threaded fastener is clean and free of debris before threading the nut to avoid damaging the nylon insert. The nylon insert is a single-use locking feature and may lose prevailing torque effectiveness if removed and reinstalled. Follow applicable mechanical and structural fastening standards for torque requirements based on the assembly design.
