Precision Brand 26166 Round Shim Spring Steel 50 Pack

Product Description

The PRECISION BRAND 26166 is a round shortening shim manufactured from 1095 spring steel, designed to fill axial gaps and control spacing in mechanical assemblies. At 0.005 inches thick with a 0.751-inch inside diameter and a 0.995-inch outside diameter, this shim provides precise dimensional control in tight tolerance applications. The 1095 spring steel construction delivers consistent resilience and resistance to deformation under load. Each package contains 50 shims, making it practical for production environments or service work requiring multiple adjustments. This part is installed by millwrights, maintenance mechanics, and precision assemblers working on shafting, bearing fits, and bolted joint alignment.

The 26166 round shim is suited for use in industrial machinery, HVAC equipment bases, pump and motor mounting, and any mechanical assembly where a 3/4-inch screw size clearance hole is needed. The shortening shim geometry allows it to be positioned around a shaft or fastener without full disassembly of the joint. Thickness tolerance is held to plus or minus 0.0005 inches, supporting applications where stack-up precision directly affects performance or alignment. Sold in a 50-piece package with a minimum order quantity of one package.

Key Features

• Shim type: shortening — installs without full shaft disassembly
• 1095 spring steel construction for durability and resistance to set under load
• Thickness of 0.005 inches with a tolerance of plus or minus 0.0005 inches for precision stack-up control
• Inside diameter of 0.751 inches fits standard 3/4-inch fastener or shaft clearance
• Outside diameter of 0.995 inches for compact footprint in tight assemblies
• 50 shims per package with a minimum order quantity of one package

Compatibility

Designed as an OEM-style replacement or standard fit shim for mechanical assemblies requiring a 3/4-inch screw size round shim with 0.005-inch thickness in 1095 spring steel.

Installation Notes

Installation is typically performed by maintenance mechanics or millwrights during shaft alignment, bearing preload adjustment, or bolted joint shimming procedures. Power down and de-energize all equipment before accessing rotating or clamped assemblies. Use calibrated micrometers to verify shim thickness and stack height before final torque of fasteners. Do not substitute shims of differing material grades when dimensional tolerance is critical to assembly function.
