Value Collection 52593688-100 Hex Lock Nut 1-14 Grade 8

Product Description

The VALUE COLLECTION 52593688-100 is a Grade 8 steel hex lock nut with a nylon insert, sized for 1-14 UNF right-hand threaded fastener applications. The nylon insert provides prevailing torque resistance, preventing the nut from backing off under vibration or dynamic loads without requiring a secondary locking device. At 1-3/64 inches high and 1-7/16 inches across the flats, this is a full-size heavy-duty lock nut. The zinc yellow dichromate finish delivers corrosion resistance suitable for industrial and outdoor environments. Mechanical contractors, millwrights, and maintenance technicians install this type of fastener in structural assemblies, machinery, and equipment where vibration-resistant fastening is required.

This nylon insert lock nut is suited for 1-14 UNF threaded rod, bolts, and studs in industrial machinery, HVAC structural frames, heavy equipment, and general mechanical assemblies. The Grade 8 material rating makes it appropriate for high-stress bolted joints where standard Grade 2 or Grade 5 hardware would be insufficient. Right-hand thread direction is standard for the vast majority of mechanical fastener applications. Sold individually with a minimum order quantity of 5 units.

Key Features

• Nylon insert locking style resists loosening under vibration without secondary lock washers
• Grade 8 steel construction for high-strength, high-stress bolted joint applications
• 1-14 UNF thread size with right-hand thread direction
• Zinc yellow dichromate finish provides corrosion and oxidation resistance
• 1-3/64 inches height and 1-7/16 inches width across flats for standard tooling fit

Compatibility

Designed for use with 1-14 UNF Grade 8 bolts and threaded rod in inch-measurement fastener systems. Compatible with standard 1-14 UNF hex bolt and stud applications requiring a prevailing torque insert lock nut.

Installation Notes

Install using a standard open-end or box wrench sized to 1-7/16 inches across the flats. Power down or de-energize any equipment before servicing fastened assemblies on electrical or mechanical systems. Nylon insert lock nuts are generally single-use — once the nylon insert has been fully threaded onto a bolt and removed, the locking torque is reduced and replacement is recommended. Follow applicable torque specifications for Grade 8 fasteners as required by the equipment manufacturer or applicable codes.
