Precision Brand 26157 Round Shim 0.005 in 3/8 in Screw 50-pack

Product Description

The PRECISION BRAND 26157 is a round shortening shim made from 1095 spring steel, designed for use in precision mechanical assemblies where controlled axial spacing or load distribution is required. At 0.005 inches thick with a 0.376-inch inside diameter and 0.557-inch outside diameter, this shim fits 3/8-inch screw sizes and provides consistent, repeatable shimming performance. Each package contains 50 pieces. The 1095 spring steel construction delivers high hardness and resilience, making these shims suitable for applications involving cycling loads or where shim stack compression must be minimized. Millwrights, maintenance technicians, and mechanical contractors are the typical installers.

These round shims are used in industrial and commercial maintenance applications wherever precise gap adjustment, load leveling, or component alignment is needed around 3/8-inch fasteners or shafts. Typical install scenarios include bearing fits, machine bases, bracket mounting, and shaft shoulder alignment. The shortening shim type is suited for reducing axial clearance in tight tolerance assemblies. The 50-piece pack supports bench stock or job-site kitting for repetitive assembly work.

Key Features

• 1095 spring steel construction for high hardness and load resilience
• Shim type: shortening, for reducing axial clearance in assemblies
• 0.005-inch nominal thickness with a tight tolerance of plus or minus 0.0005 inches
• Fits 3/8-inch screw size with 0.376-inch inside diameter
• 0.557-inch outside diameter for broad load distribution around the fastener
• 50-piece package supports bench stock and repetitive assembly applications

Compatibility

Designed as an OEM-style precision shim for mechanical assemblies using 3/8-inch fasteners or shoulder diameters requiring shortening-type axial adjustment.

Installation Notes

Installation is typically performed by millwrights or mechanical maintenance technicians. Power down and de-energize all equipment before disassembling fastened joints. Shims should be stacked flat and free of burrs or debris to maintain tolerance accuracy across the stack. Consult applicable machinery OEM documentation for allowable shim stack height and fastener torque requirements.
