Value Collection 857420BR Hex Flange Lock Nut 3/4-10

Product Description

The VALUE COLLECTION 857420BR is a hex flange lock nut with a nylon insert locking mechanism, designed for use in threaded fastener assemblies requiring reliable vibration resistance. The nut features a 3/4-10 UNC thread size, right-hand thread direction, and is manufactured from Grade 2 steel with a zinc finish for corrosion protection. The integrated flange distributes clamping load over a wider surface area, reducing the need for a separate washer. Measured at 13/16 inches high with a 1-1/8 inch width across flats, this nut is a standard-sized component suitable for general-purpose mechanical and structural applications. Installation is straightforward for any trade or maintenance professional working with inch-standard fasteners.

This hex flange lock nut is suited for general industrial, mechanical, and construction applications where a secure, vibration-resistant threaded connection is required. The nylon insert grips the mating bolt thread once engaged, preventing loosening under dynamic or vibratory loads. The flange base makes it particularly useful in assemblies where load distribution matters and space for a separate washer is limited. This part is sold individually, with a minimum order quantity of 5 units.

Key Features

• 3/4-10 UNC thread size with right-hand thread direction
• Nylon insert locking style prevents loosening under vibration
• Integrated flange eliminates need for a separate washer in most applications
• Grade 2 steel construction for general-purpose strength
• Zinc finish provides baseline corrosion resistance
• Height of 13/16 inches and 1-1/8 inches across flats for standard wrench compatibility

Compatibility

Designed as a general-purpose replacement or standard hex flange lock nut for assemblies using 3/4-10 UNC inch-standard threaded fasteners.

Installation Notes

Installation requires a standard open-end or combination wrench sized to 1-1/8 inches across flats. Engage the nylon insert fully onto the mating bolt thread by hand before applying torque to avoid cross-threading. The nylon insert provides a prevailing torque locking action and is generally rated for single use — inspect the insert before reuse. Follow applicable mechanical or structural codes for torque requirements based on fastener grade and application.
