Value Collection 897288BR Hex Lock Nut 1-14 Grade 8

Product Description

The VALUE COLLECTION 897288BR is a 1-14 UNF hex lock nut with a nylon insert locking mechanism, manufactured from Grade 8 steel with a bright, uncoated finish. The nylon insert creates prevailing torque by deforming around mating threads, resisting loosening from vibration and dynamic loads without requiring chemical thread-locking compounds. At 1-3/64 inches in height and 1-7/16 inches across the flats, this nut fits standard 1-14 right-hand threaded fastener applications. It is suited for mechanical assembly work where a reusable, torque-resistant nut is required.

This hex lock nut is used in heavy-duty mechanical and structural assemblies where vibration resistance is critical. The 1-14 UNF thread designation indicates a fine-thread fastener, common in applications requiring precise clamping force or use in thinner-walled materials. Grade 8 steel construction makes it appropriate for high-strength bolted joints in industrial, agricultural, and heavy equipment assembly environments. The bright, uncoated finish is standard for indoor or protected installations where corrosion exposure is limited.

Key Features

• Nylon insert locking style provides vibration-resistant prevailing torque without adhesives
• Grade 8 steel construction for high-strength bolted joint applications
• 1-14 UNF right-hand thread for fine-thread fastener compatibility
• Bright, uncoated finish suitable for protected or indoor assemblies
• 1-7/16 inch width across flats for standard wrench sizing
• Does not meet military specifications — intended for commercial and industrial use

Compatibility

Designed for use with 1-14 UNF right-hand threaded fasteners in Grade 8 or compatible high-strength bolted assemblies following inch measurement standards.

Installation Notes

Installation is performed by mechanics, millwrights, or maintenance technicians using a standard 1-7/16 inch open-end or box wrench. Always verify the mating bolt thread pitch and grade before installation. Nylon insert lock nuts are designed to be reusable but should be inspected before reuse to confirm the insert still provides adequate prevailing torque resistance. Do not apply thread-locking compounds to nylon insert lock nuts.
