Value Collection SNFI2087-015BX Slotted Hex Lock Nut 7/8-14

Product Description

The VALUE COLLECTION SNFI2087-015BX is a slotted hex lock nut designed for secure, vibration-resistant fastening in demanding mechanical and industrial applications. Manufactured from Grade 2 steel with a bright uncoated finish, this nut features a 7/8-14 UNF (Unified National Fine) right-hand thread pattern. It measures 0.75 inches in height and 1.3125 inches across the flats, conforming to standard inch-system fastener dimensions. The slotted design accommodates a cotter pin or safety wire for added locking security in assemblies subject to movement, load cycling, or vibration. Licensed tradespeople, maintenance mechanics, and industrial assemblers typically specify this type of nut where standard hex nuts may back off under service conditions.

This slotted hex lock nut is suited for use in general mechanical assemblies, automotive drivetrain components, agricultural equipment, and light industrial machinery. The 7/8-14 UNF thread size is a fine-pitch designation, commonly found in applications requiring precise clamping force and tight thread engagement. The bright uncoated finish is appropriate for indoor or controlled-environment installations where corrosion exposure is minimal. It is sold and packaged as a single unit.

Key Features

Compatibility

Designed as a standard UNF slotted hex lock nut for use with any 7/8-14 right-hand threaded bolt or stud conforming to inch-system fastener specifications.

Installation Notes

Installation should be performed by a qualified mechanic or assembler familiar with UNF fastener standards. Always ensure the mating bolt or stud thread is clean and free of damage before installation. Use an appropriately sized open-end or box wrench sized for 1.3125 inches across the flats, and install a cotter pin through the castellation slots and bolt hole after reaching the required assembly position to secure the nut against rotation. Do not overtighten or hammer the nut onto the thread, as this can damage the thread form and compromise locking function.
