The PRECISION BRAND 26600 is a 360-piece assorted kit of metric shoulder screw shortening shims designed to provide precise axial adjustment of shoulder screws in mechanical assemblies. These shims allow technicians and machinists to fine-tune shoulder screw length without machining or modifying the fastener itself, reducing installation time and material waste. The assorted kit format means the correct shim thickness is readily available on the bench, making the 26600 a practical addition to any maintenance, repair, or original equipment manufacturing workflow. The kit weighs 1 pound and is sold as a single unit.
Shoulder screw shortening shims are used in precision mechanical assemblies where shoulder screw standoff height must be controlled tightly. Typical applications include fixture building, jig assembly, machine tool maintenance, and industrial equipment repair. The metric sizing in this kit suits equipment built to metric fastener standards, which is common in imported machinery, automotive tooling, and modern industrial equipment. Maintenance technicians and tool room machinists are the primary installers of these shims.
Designed as an OEM-style fit for use with metric shoulder screws in precision mechanical assemblies and fixtures where axial length adjustment is required.
Installation is performed by qualified machinists or maintenance technicians as part of fastener and fixture assembly work. Power down and lockout any equipment before disassembling assemblies to access shoulder screws. Select the appropriate shim thickness from the assortment to achieve the target shoulder screw standoff, and verify fit before final torque. Handle shims carefully to avoid bending or distorting thin pieces during installation.
