Precision Brand 26158 Round Shim Spring Steel 50-pack

Product Description

The PRECISION BRAND 26158 is a round shortening shim made from 1075 spring steel, designed to fill gaps, adjust tolerances, and level or align mechanical components in assembly and maintenance applications. At 0.0150 inches thick with an inside diameter of 0.3760 inches and an outside diameter of 0.5570 inches, this shim provides precise dimensional control where standard fastener clearances require fine adjustment. Each package contains 50 shims, making it practical for production line use or field service kits. The 1075 spring steel construction delivers consistent elasticity and resistance to deformation under load.

This round shim is suited for use with 3/8 inch screws and fasteners in mechanical, HVAC, and general industrial assembly applications. The shortening shim type is commonly used to reduce stack height or adjust component spacing during equipment installation, alignment, or repair. The 50-piece pack supports both single-job and repeat-task scenarios across manufacturing, maintenance, and trade service environments.

Installation Notes

Shims should be installed by a qualified mechanic or maintenance technician. De-energize and lockout any equipment before disassembly or shimming operations. Ensure mating surfaces are clean and free of debris before placing shims to maintain accurate stack-up tolerances. Do not exceed the load ratings of the fastener or joint assembly when stacking multiple shims.
