Value Collection SNFI2100-010BX Hex Slotted Lock Nut 1-14

Product Description

The VALUE COLLECTION SNFI2100-010BX is a slotted hex lock nut machined to a 1-14 UNF thread specification in Grade 2 steel with a bright, uncoated finish. It measures 55/64 inches in height and 1-1/2 inches across the flats, with a right-hand thread direction. Lock nuts of this type are used where vibration resistance and positive retention are required without relying on thread friction alone. The slotted design accepts a cotter pin or safety wire through a corresponding drilled fastener, providing a mechanical anti-rotation lock. Licensed trades and maintenance professionals in HVAC, plumbing, and industrial equipment service reach for this nut when a standard hex nut is not sufficient to maintain clamp load under dynamic loads.

This slotted lock nut is suited for general industrial and mechanical assembly applications where inch-series fasteners are specified. Common installation scenarios include shaft-end retention on rotating equipment, linkage assemblies, and structural connections calling for a 1-14 UNF coarse-fine thread fastener. The uncoated finish is appropriate for dry indoor environments or applications where a topcoat will be applied at assembly. It is sold in multiples of 10 units minimum order quantity with a package quantity of 1.

Key Features

• Slotted hex design accepts cotter pin or safety wire for positive mechanical locking
• 1-14 UNF right-hand thread for standard inch-series assemblies
• Grade 2 steel construction for general-purpose fastening loads
• Bright uncoated finish suitable for secondary coating or dry indoor use
• 55/64 inch height and 1-1/2 inch width across flats for standard wrench fitment

Compatibility

Designed for use with any 1-14 UNF externally threaded fastener or shaft end in inch-series mechanical assemblies conforming to UNF thread standards.

Installation Notes

Installation is performed by maintenance mechanics, millwrights, or licensed tradespeople using a standard open-end or box wrench sized to 1-1/2 inches across the flats. De-energize and lock out all equipment before servicing fasteners on rotating or pressurized assemblies. After torquing to the required clamp load per the equipment manufacturer's specification, align the nearest slot with the cotter pin hole and install an appropriately sized cotter pin or safety wire to prevent back-off. Do not reuse a cotter pin once removed.
