Precision Brand 26163 Round Shim Spring Steel Pack of 50

Product Description

The PRECISION BRAND 26163 is a round shortening shim made from 1095 spring steel, designed for precision shimming and spacing applications in mechanical assemblies. At 0.0050 inches thick with an inside diameter of 0.626 inches and an outside diameter of 0.870 inches, this shim is suited for fine tolerance adjustments around 5/8-inch fasteners or shoulders. The 1095 spring steel construction provides good hardness and resilience for load-bearing shimming tasks. Each package contains 50 shims, making it practical for jobs requiring consistent repeated use or stocking a service van.

Round shortening shims like the 26163 are used across HVAC, mechanical, plumbing, and general industrial applications wherever tight dimensional tolerances are required between mating components. Typical use cases include leveling flanges, adjusting bearing clearances, setting gear mesh, and correcting dimensional variation in shaft assemblies. The 5/8-inch screw size fit makes these well suited for standard mechanical fastener configurations found in residential and light commercial equipment service and installation.

Key Features

• 1095 spring steel construction for hardness and load-bearing resilience
• Shortening shim type for precise gap and tolerance adjustments
• 0.0050-inch nominal thickness with a tolerance of plus or minus 0.00050 inches
• Inside diameter of 0.626 inches fits standard 5/8-inch screws and shoulders
• Pack of 50 shims per package for repeated or multi-point installations

Compatibility

Designed as an OEM-style replacement and standard-fit round shim for mechanical assemblies using 5/8-inch fasteners or shoulder diameters requiring precision shimming.

Installation Notes

Round shims are installed by machinists, millwrights, and skilled trade technicians during assembly or component adjustment. Power down and de-energize all equipment before disassembling any mechanical assembly. Ensure mating surfaces are clean and free of debris before seating the shim to maintain dimensional accuracy. Do not stack mismatched shims of different materials without confirming load and hardness compatibility.
