Precision Brand 26164 Round Shim Spring Steel 5/8 in Pack 50

Product Description

The PRECISION BRAND 26164 is a round shortening shim manufactured from 1075 spring steel. Shims of this type are used to fill gaps, adjust spacing, and take up tolerance in mechanical assemblies. This piece measures 0.015 inches thick with an inside diameter of 0.626 inches and an outside diameter of 0.870 inches, sized for 5/8 inch screw or shoulder applications. The tight thickness tolerance of plus or minus 0.00075 inches makes it suitable for precision alignment work. Machinists, millwrights, and maintenance technicians commonly install these during equipment assembly, shaft alignment, and bearing seat adjustment.

These round shims are used in industrial and commercial maintenance applications where close-tolerance spacing is required. The shortening shim type is commonly placed under flanges, between mating surfaces, or around fastener shoulders to control stack height and reduce play in mechanical joints. The 1075 spring steel construction offers good hardness and resilience, making these shims appropriate for moderate-load applications where the shim must resist compression and maintain its set thickness under service conditions. This package contains 50 pieces.

Compatibility

Designed as an OEM-style replacement or standard stock shim for 5/8 inch fastener and shoulder diameter applications in mechanical and industrial assemblies requiring 1075 spring steel round shims.

Installation Notes

Shim installation is typically performed by machinists, millwrights, or maintenance technicians as part of equipment assembly or alignment procedures. Ensure the mating surfaces are clean and free of burrs before placing the shim to maintain the specified thickness tolerance. Disengage all power and relieve any mechanical load on the assembly before disassembly or shim replacement. Do not bend, nick, or distort the shim during handling, as deformation will affect the achieved tolerance.
