Shims

Ring Shims

Precisely align, level, and adjust spacing on fasteners and shafts with these shims.

Ring Shim Sets

Be prepared with ring shims in a variety of thicknesses. These shims fit around fasteners and shafts to precisely align, level, and adjust spacing.

Wide-Rim Ring Shims

Also known as machinery bushings, these shims have an oversized OD to create a larger bearing surface for reduced wear between moving parts.

Disc Shims

Use these round shims as they are, or punch out the middle to create the ID you need.

Shims for Keyed Shafts

Precisely shaped to fit snugly on keyed shafts, these shims align, level, and space components. Because of their tight fit, they also help components rotate in unison with the shaft.

Shim Sets for Keyed Shafts

Be prepared with shims in a variety of thicknesses. Also known as arbor spacers, these shims are notched to fit over keyed shafts.

Shims for D-Profile Shafts

These shims are shaped to fit over D-profile shafts. Use them to precisely align, level, and adjust spacing.

Shim Sets for D-Profile Shafts

Be prepared with shims in a variety of thicknesses. These shims are shaped to fit over D-profile shafts. Use them to precisely align, level, and adjust spacing.

Multi-Slotted Shims

Use a single shim on feet or positioning arms that are secured with multiple fasteners. The slots let you insert, remove, and adjust the shims without disassembling your machinery. Also known as finger shims.

Shim Stock

Cut this stock into custom shapes to fit your application.

Shim Stock Sets

Keep shim stock in a variety of thicknesses on hand with these sets. Cut into custom shapes to fit your application.

Split Lock Washers

As a screw is tightened, these washers flatten to add tension to the joint and prevent loosening from small amounts of vibration.

Spacers and Standoffs

Zinc-Plated Steel Unthreaded Spacers

The zinc plating provides some corrosion resistance.

Made-to-Order Unthreaded Spacers

Choose the OD, ID, length, and material and we will accommodate your unique spacer needs.

Polished Unthreaded Spacers

With their mirror-like finish, these are the go-to spacers when appearance matters.

Slotted Unthreaded Spacers

An economical alternative to standard unthreaded spacers.

Unthreaded Spacers for Keyed Shafts

Also known as arbor spacers, these are notched to space components on a keyed shaft.
