Precision Brand 26159 Round Shim Spring Steel 3/8 in Pack 50

Product Description

The PRECISION BRAND 26159 is a round shortening shim made from 1075 spring steel, designed for precise axial spacing and load distribution in mechanical assemblies. At 0.032 inches thick with an inside diameter of 0.376 inches and an outside diameter of 0.557 inches, this shim fits a 3/8-inch screw and delivers consistent clamping performance where tight dimensional control is required. The 1075 spring steel construction provides the hardness and resilience needed to maintain set thickness under sustained compressive load. Each package contains 50 pieces, supporting production runs and field service kits alike.

This shim is suited for use in industrial maintenance, OEM assembly, and precision mechanical repair applications across manufacturing, HVAC equipment frames, pump mounts, motor bases, and similar mechanical systems. The shortening shim type makes it appropriate for applications where stack height reduction or precise gap fill between mating components is needed. Machinists, millwrights, and mechanical contractors commonly use parts like this during equipment alignment and shimming procedures.

Key Features

• Sold in a 50-piece package with a minimum order quantity of 1

Compatibility

Designed as an OEM-style round shim for use with 3/8-inch fasteners in mechanical assemblies requiring controlled axial spacing with spring steel construction.

Installation Notes

Installation is performed by machinists, millwrights, or mechanical technicians during assembly or alignment procedures. De-energize and lock out all equipment before disassembling any shim stack. Verify that mating surfaces are clean and free of burrs before seating the shim to ensure the stated thickness tolerance is maintained. Do not substitute shims of differing material grades or thickness values without confirming the assembly design requirements.
