Precision Brand 26152 Round Shim Spring Steel 1/4 in Screw

Product Description

The PRECISION BRAND 26152 is a 1075 spring steel round shim used to fill gaps, adjust alignment, and take up clearance in mechanical assemblies. At 0.015 inches thick with an inside diameter of 0.252 inches and an outside diameter of 0.366 inches, this shortening-type shim is sized for 1/4-inch screw applications. Each package contains 50 pieces, making it suitable for shop stock or multi-point shimming tasks. The tight thickness tolerance of plus or minus 0.00075 inches supports precise stack-up control in assemblies where dimensional accuracy matters.

This shim is used across industrial, mechanical, and equipment maintenance applications where 1/4-inch fastener clearances need to be shimmed to spec. Typical install scenarios include machinery alignment, bracket mounting, bearing seats, and shaft shoulder adjustments. The shortening shim type makes it appropriate for reducing shoulder length or taking up axial play in bolted assemblies. Machinists, millwrights, and maintenance technicians commonly keep these on hand for production and repair work.

Key Features

• Shortening-type round shim for axial gap adjustment at 1/4-inch fastener locations
• 1075 spring steel construction provides consistent hardness and elasticity under clamp load
• 0.015 inch nominal thickness with a tolerance of plus or minus 0.00075 inches for precise stack-up control
• 0.252 inch inside diameter fits 1/4-inch screw or shaft shoulders cleanly
• Pack of 50 pieces supports multi-point jobs and shop stock replenishment

Compatibility

Designed for use with 1/4-inch screw sizes in mechanical assemblies requiring shortening-type round shims in 1075 spring steel.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians during assembly or alignment procedures. Always de-energize and lock out equipment before disassembling any mechanical assembly to place or adjust shims. Inspect mating surfaces for burrs or debris before placing shims to ensure accurate stack-up readings. Do not substitute shim thickness combinations that fall outside the engineered tolerance stack for the assembly.
