Value Collection SNFI5062-025BX 5/8-18 Hex Slotted Lock Nut

Product Description

The VALUE COLLECTION SNFI5062-025BX is a 5/8-18 UNF hex slotted lock nut manufactured from Grade 2 steel with a bright uncoated finish. The slotted design accepts a cotter pin or safety wire when used with a drilled-shank fastener, providing positive locking in vibration-prone assemblies. At 35/64 inches tall and 15/16 inches across the flats, this is a standard-dimension inch-series nut suitable for right-hand threaded fasteners. Weighing 0.061 pounds, it is sized for general mechanical and structural fastening work across a wide range of trades including HVAC equipment assembly, plumbing fixture mounting, and light structural applications.

This nut is used wherever a conventional hex nut is insufficient to resist vibration-induced loosening. Typical installations include equipment frame assemblies, bracket mounting, pump and blower hardware, and general mechanical sub-assemblies. It is compatible with any 5/8-18 UNF right-hand threaded bolt or stud. The uncoated bright finish suits indoor and dry-environment applications. This fastener ships in a minimum order quantity of 25 pieces, making it practical for field stock or small project needs.

Key Features

• Slotted hex lock nut design accepts cotter pin or safety wire for positive vibration resistance

• Grade 2 steel construction provides adequate strength for general-duty fastening
• Bright uncoated finish suitable for dry indoor environments
• Standard 15/16-inch across-flats dimension fits common open-end and combination wrenches
• Conforms to UNF fastener standard; does not meet military specifications

Compatibility

Designed for use with 5/8-18 UNF right-hand threaded fasteners in general mechanical, HVAC, plumbing, and light structural assemblies requiring a slotted lock nut.

Installation Notes

Installation is performed with a standard open-end or combination wrench sized to 15/16 inches across the flats. Always verify the mating bolt or stud carries a matching 5/8-18 UNF right-hand thread specification before assembly. When using a cotter pin for positive locking, align the nut slot with the drilled shank hole and insert an appropriately sized cotter pin per the fastener manufacturer's guidance. Follow applicable mechanical and structural codes for torque and locking requirements in the specific application.
