Precision Brand 25999 Arbor Shim Kit 150 Piece Assorted

Product Description

The PRECISION BRAND 25999 is a 150-piece assorted arbor shim kit designed for precise spacing and alignment in mechanical and industrial applications. The kit includes shims in three thicknesses: 0.020 inches, 0.031 inches, and 0.125 inches, giving technicians a range of sizing options in a single package. Arbor shims are used to close gaps, reduce play, and achieve accurate positioning on shafts, arbors, and rotating assemblies. This kit is suited for machinists, millwrights, and maintenance technicians who need reliable shimming stock on hand for a variety of fit and alignment tasks.

This assorted kit is well-suited for both shop and field use where multiple shim thicknesses are needed without ordering individual sizes. Common applications include aligning saw blades, grinding wheels, and rotating tool arbors, as well as general mechanical assembly work in manufacturing, maintenance, and repair environments. Having three distinct thicknesses in one kit reduces downtime and the need for separate orders when tolerances vary by job.
