Unthreaded Spacers

18-8 Stainless Steel Unthreaded Spacers

18-8 stainless steel spacers have good corrosion resistance.

Aluminum Unthreaded Spacers

Made of aluminum, these spacers are lightweight and mildly corrosion resistant.

Zinc-Plated Steel Unthreaded Spacers

The zinc plating provides some corrosion resistance.

316 Stainless Steel Unthreaded Spacers

These spacers have excellent corrosion resistance and are passivated for enhanced protection.

Zinc-Plated Brass Unthreaded Spacers

Brass makes these spacers electrically conductive and the zinc-plated finish adds corrosion resistance.

Black-Anodized Aluminum Unthreaded Spacers

The anodized coating on these lightweight spacers provides increased abrasion resistance over uncoated aluminum.

Titanium Unthreaded Spacers

Choose titanium spacers for their high strength-to-weight ratio and excellent corrosion resistance.

Nylon Unthreaded Spacers

These spacers have excellent wear and abrasion resistance. Exposure to moisture may cause them to expand.

Polyethylene Unthreaded Spacers

Almost nonabsorbent, these unthreaded LDPE and HDPE spacers won't swell when exposed to water.

Polypropylene Unthreaded Spacers

Polypropylene spacers have a hard surface and resist many chemicals and solvents.

Acetal Unthreaded Spacers

Naturally slippery and wear resistant, acetal spacers also offer some resistance to moisture.

PTFE Unthreaded Spacers

PTFE spacers have a slippery surface and surpass most plastic spacers when it comes to chemical resistance and performance in extreme temperatures.

PEEK Unthreaded Spacers

Use PEEK spacers as an alternative to metal spacers in high-temperature, high-stress applications. They resist chemicals, wear, and moisture.

Polycarbonate Unthreaded Spacers

Made of FDA-listed material, these clear spacers can be used in food and beverage applications.

Unthreaded Spacer Stock

Cut stock to the length you need.

Vibration-Damping Unthreaded Spacers

Reduce vibration, shock, and noise with these spacers that compress between components.

Polished Unthreaded Spacers

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

Made-to-Order Unthreaded Spacers

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

Electrical-Insulating Unthreaded Spacers

Protect components from electrical charges.

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.

Unthreaded Spacers for Angles

The 45° end fits against an angled surface to create a flat surface for connection.

Unthreaded Spacers for Tubes

Also known as saddle washers, the curved end fits against round objects such as tube and pipe.

Press-Fit Unthreaded Spacers

Also known as captive spacers, the splines on these bite into a panel for a permanent hold.

Round Shims

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.

Shims for D-Profile Shafts

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

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.
