Description

DESCRIPTION

Hex Slotted Nut - Zinc Plate - 1-1/4 UNF

(Price per unit)

Hex slotted nuts are hexagonal fasteners that feature six wide slots spaced evenly at 60° intervals around the top face. They are generally considered to have about 80% of the strength of a comparable full-thickness nut of the same size, grade, and style.

They are designed for use with bolts or studs that have a drilled hole through the threaded portion. A cotter pin is passed through the hole to lock the nut in place, preventing loosening or rotation. The connection remains secure until the pin is removed or breaks.

Main features and uses:

  • Hex nut with six top slots for locking with a cotter pin
  • Approximately 80% strength compared to standard full-thickness nuts
  • Used with drilled bolts or studs for pin locking
  • Common in securing wheel bearings on spindles
  • Can be used in place of castle nuts, but have a lower profile due to the flat top design
  • Not intended for use with lock washers
  • Also referred to as spindle nuts

They are typically chosen where a reliable mechanical locking method is required in rotating or vibration-prone assemblies.
