Description

DESCRIPTION

Thin Hex Lock Nut - 304 Stainless Steel - 1/2UNC (Box=50)

(Price per unit)

Hex thin lock nuts (half height hex nuts), also known as lock or jam nuts, are designed to be installed beneath a larger nut. When tightened, the thinner nut deforms slightly, creating a locking effect on the thread as the larger nut is secured.

  • Can be useful where head clearance or thread protrusion is limited and a full-height nut will not fit.
  • The clamping capacity is lower than that of a standard nut due to its reduced height. Use in pairs (one thin nut and one full-height nut) to create a jam-locking arrangement.

Nuts must be selected to match a compatible bolt grade and material system to ensure proper strength and performance.

(Common uses) Adjustable mechanical assemblies (Valve adjusters, turnbuckles, jig fixtures)

Also known as: Hex Jam Nuts, Jam Lock Nuts, Half Nuts
