Value Collection R52001635 Hex Lock Nut 3/8-24 Grade 8

Product Description

The VALUE COLLECTION R52001635 is a nylon insert hex lock nut designed to resist loosening under vibration and dynamic loading. It is manufactured from Grade 8 steel with a zinc yellow dichromate finish that provides corrosion resistance in demanding environments. The nut features a 3/8-24 UNF right-hand thread and measures 15/32 inches in height with a width across flats of 9/16 inches. The embedded nylon insert grips the mating bolt threads without damaging them, maintaining clamping force over repeated thermal and mechanical cycling. Mechanical contractors, millwrights, and equipment technicians install this fastener where standard hex nuts are insufficient.

This hex lock nut is suited for general industrial, automotive, and structural fastening applications requiring a fine-thread UNF fastener with positive locking. The 3/8-24 thread pitch makes it appropriate for applications where fine thread engagement is specified, such as precision assemblies, suspension components, and equipment frames. It is sold in minimum order quantities of 10 units and is appropriate for both original equipment assembly and field service replacement.

Key Features

• Nylon insert locking style prevents loosening from vibration without damaging mating threads
• Grade 8 steel construction provides high tensile and proof load ratings for demanding fastening applications
• Zinc yellow dichromate finish offers corrosion and oxidation resistance
• 3/8-24 UNF right-hand thread conforms to inch fastener standards
• 15/32 inch height and 9/16 inch width across flats fit standard hex tooling

Compatibility

Designed as a standard UNF nylon insert hex lock nut for use with 3/8-24 inch-series bolts and threaded rod in general industrial, mechanical, and structural assemblies.

Installation Notes

Installation is performed with a standard hex wrench or socket sized to 9/16 inches across flats. De-energize, de-pressurize, or otherwise make safe any assembly before removing or replacing fasteners. Nylon insert lock nuts are generally rated for single use — once the nylon insert has been run down, the locking torque may be reduced and replacement is recommended. Consult applicable mechanical codes and the original equipment manufacturer specifications for required torque values.
