Value Collection SNI5175-005BX Slotted Lock Nut 1-3/4-5 Unc

Product Description

The VALUE COLLECTION SNI5175-005BX is a slotted lock nut sized 1-3/4-5 UNC, manufactured from Grade 2 steel with a bright, uncoated finish. It measures 1.5 inches in height and 2.625 inches across the flats, with a right-hand thread direction. Slotted lock nuts are designed to be used with a cotter pin or safety wire threaded through the slots, preventing the nut from backing off under vibration or dynamic load. This fastener is suited for general mechanical and structural assemblies where a positive locking method is required.

This nut is appropriate for industrial, mechanical, and trade applications where large-diameter UNC fasteners are specified. Typical uses include shaft retention, bearing preload adjustment, and heavy-equipment assemblies. The bright uncoated finish is standard for indoor or protected environments. It is sized for use in inch-measurement fastener systems and follows UNC thread standards.
