The VALUE COLLECTION SNI2100-025BX is a slotted lock nut designed for use with 1-8 UNC right-hand threaded fasteners. Manufactured from Grade 2 steel with a bright, uncoated finish, this nut measures 55/64 inches in height and 1-1/2 inches across the flats. The slotted design accommodates a cotter pin or safety wire through a corresponding castellated shaft or bolt, providing positive retention in applications subject to vibration or movement. This is a general-purpose inch-series fastener suited for mechanical assemblies across HVAC, plumbing, and industrial maintenance work.
This slotted lock nut is used wherever a 1-8 UNC threaded connection requires positive locking. Typical applications include equipment mounting, shaft retention, and structural fastening in both residential and light commercial settings. The bright uncoated finish is appropriate for dry or protected interior environments. Trades including HVAC technicians, plumbers, and general maintenance mechanics commonly stock this size for equipment repair and replacement work.
Designed for use with 1-8 UNC right-hand threaded bolts and studs in general mechanical and trade applications where a Grade 2 steel slotted lock nut is specified.
Installation should be performed with an appropriately sized open-end or box wrench sized for 1-1/2 inches across the flats. Always align the slots with the cotter pin hole in the bolt or shaft before inserting a cotter pin to lock the nut in position. Do not substitute a cotter pin with an undersized or improper retainer. Verify thread condition on the mating fastener before installation to ensure full thread engagement.
