Precision Brand 26151 Shoulder Screw Shortening Shims 50 Pk

Product Description

The PRECISION BRAND 26151 is a pack of 50 assorted shoulder screw shortening shims engineered for precise axial length adjustment of shoulder screws in mechanical assemblies. Each shim measures 0.252 inches in inner diameter, 0.366 inches in outer diameter, and 0.005 inches in thickness, allowing technicians and machinists to fine-tune shoulder screw protrusion with close dimensional control. These shims are used wherever a shoulder screw must be shortened to a specific stack height without machining the screw itself. The pack format provides a ready supply for bench work and field service situations alike.

Shoulder screw shortening shims are commonly used in industrial machinery, jigs and fixtures, conveyor systems, and mechanical linkages where shoulder screws serve as pivot pins, guide posts, or spacers. The 50-piece assorted pack is suited for maintenance shops, fabrication environments, and production facilities that perform regular mechanical assembly or repair work. Technicians working on equipment with tight tolerance requirements will find the consistent 0.005-inch thickness useful for incremental stack adjustments.

Key Features

• 0.005-inch thickness allows incremental axial adjustment of shoulder screw length
• Inner diameter of 0.252 inches fits standard shoulder screw shanks
• Outer diameter of 0.366 inches provides adequate bearing surface around the screw shoulder
• 50-piece assorted pack supports multiple jobs from a single supply
• Sold as a single pack with a minimum order quantity of one

Compatibility

Designed as a standard shortening shim for use with shoulder screws having a shank diameter compatible with a 0.252-inch inner diameter bore, typical in general industrial and mechanical assembly applications.

Installation Notes

Installation is performed by machinists or mechanical technicians during assembly or scheduled maintenance. De-energize and lock out all affected equipment before disassembling any mechanical linkage or fastener assembly. Stack shims as needed beneath the shoulder screw head to achieve the desired effective shoulder length, verifying final stack height with a micrometer or caliper before fully torquing the fastener. Follow applicable equipment manufacturer specifications for fastener torque requirements.
