The PRECISION BRAND 26500 is a 330-piece assorted metric shoulder screw shim kit designed to fine-tune the fit and alignment of shoulder screws in precision assemblies. These shims slip over the shoulder of a metric shoulder screw to extend effective shoulder length, allowing technicians to achieve exact stack heights without machining custom spacers. The kit covers a range of thicknesses in a single package, making it a practical bench stock item for maintenance shops and assembly facilities. Millwrights, machinists, and industrial maintenance technicians are the primary installers of this product.
Shoulder screw shims are used wherever precision axial positioning is required — fixture building, jig assembly, conveyor systems, and general industrial machinery. The metric sizing in this assortment suits equipment manufactured to metric standards, which is common in automotive, food processing, and packaging industries. Having an assorted kit on hand reduces downtime by eliminating the need to order individual shim sizes during a repair or build. This kit is sold as a single unit containing all 330 pieces.
Designed as an OEM-style assortment for use with metric shoulder screws in industrial machinery, fixtures, jigs, and precision mechanical assemblies.
Shoulder screw shims are typically installed by machinists or maintenance technicians during mechanical assembly or repair. De-energize and lock out all equipment before disassembling any fastener joint. Select the appropriate shim thickness to achieve the desired shoulder length and stack height, then confirm fit before fully torquing the shoulder screw to the fastener manufacturer's specification. Avoid mixing metric and inch-series shims in the same assembly.
