Precision Brand 26154 Round Shim Spring Steel Pack of 50

Product Description

The PRECISION BRAND 26154 is a round shortening shim made from 1095 spring steel, engineered for precision spacing and load distribution in mechanical assemblies. With an inside diameter of 0.3130 inches and an outside diameter of 0.4240 inches, this shim fits 5/16-inch screw sizes and delivers consistent, reliable performance under load. The 0.0050-inch nominal thickness and tight thickness tolerance of 0.00050 inches make it well-suited for applications where exact stack height control is critical. Sold in a package of 50, this shim is a standard component stocked by maintenance technicians, millwrights, and mechanical contractors for both production and field service use.

This shim is used wherever precise gap adjustment, alignment, or load distribution is needed around a 5/16-inch fastener. Typical applications include machinery alignment, pump and motor mounting, bracket leveling, and equipment shimming in industrial, commercial, and HVAC mechanical contexts. The shortening shim type is designed to reduce stack height or fill gaps in bolted assemblies. The 1095 spring steel construction provides good hardness and resistance to compression set, making it appropriate for use in high-cycle or vibration-prone environments.

Compatibility

Designed for use with 5/16-inch fasteners in mechanical assemblies requiring precision shimming, alignment, or spacing. Suitable for general industrial, commercial, and mechanical service applications where 1095 spring steel shortening shims are specified.

Installation Notes

Installation is typically performed by millwrights, maintenance technicians, or mechanical contractors. De-energize and lock out all equipment before beginning any shimming or alignment work per applicable OSHA lockout/tagout procedures. Verify shim stack thickness with a calibrated micrometer before final fastener torque. Do not substitute shim thickness outside the engineered specification for the assembly being serviced.
