Unthreaded Spacers

Aluminum Unthreaded Spacers

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

18-8 Stainless Steel Unthreaded Spacers

18-8 stainless steel spacers have good corrosion resistance.

316 Stainless Steel Unthreaded Spacers

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

Zinc-Plated Steel Unthreaded Spacers

The zinc plating provides some corrosion resistance.

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

Withstanding salt water, acids, and chemicals, these spacers resist corrosion better than any other metal spacer we offer. They have a high strength-to-weight ratio and are about 40% lighter than steel spacers.

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.

PEEK Unthreaded Spacers

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

Polycarbonate Unthreaded Spacers

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

Vibration-Damping Unthreaded Spacers

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

Unthreaded Spacer Stock

Cut stock to the length you need.

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.

Polished Unthreaded Spacers

A nickel-chrome plating gives these spacers a mirror-like finish.

Sanitary Unthreaded Spacers

Create space to clean between components on food processing lines and other sanitary equipment.

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.

Unthreaded Inserts

Steel Unthreaded Inserts for Plastic

A zinc-plated finish gives these steel inserts mild corrosion resistance.

Aluminum Unthreaded Inserts for Plastic

These aluminum inserts are lightweight, nonmagnetic, and mildly corrosion resistant.

Brass Unthreaded Inserts for Plastic

Made from brass, these inserts are nonmagnetic, mildly corrosion resistant, and electrically conductive.

Unthreaded Inserts for Metal

Protect bolts from sideways (shear) pressure.

Unthreaded Spacer Assortments

Have different sizes and lengths of spacers ready for a variety of jobs.

Drill Bushings

Press-Fit Drill Bushings

Also known as jig bushings, these drill bushings fit inside fixture plate holes to precisely guide drill bits, counterbores, reamers, and other cutting tools. They improve accuracy so your drilled holes and cuts are consistent from part to part.

Thin-Wall Press-Fit Drill Bushings

Drill holes close together. These bushings have a thinner wall than typical bushings to fit side by side in a fixture plate.

Made-to-Order Press-Fit Drill Bushings

Choose the ID, OD, and length you need.

Press-Fit Reamer Bushings

With ID tolerances sized specifically for reamers, these bushings ensure steady and precise hole finishing. Press them into a fixture plate with a manual or hydraulic press for permanent installation.

Finish-Your-Own Press-Fit Drill Bushings

Larger OD tolerances than standard press-fit bushings allow for finishing. Bushings should be machine ground.

Metric Press-Fit Drill Bushings

Also known as jig bushings, these metric drill bushings fit inside fixture plate holes to precisely guide drill bits, counterbores, reamers, and other cutting tools. They improve accuracy so that your drilled holes and cuts are consistent from part to part.

Made-to-Order Metric Press-Fit Drill Bushings

Choose the ID, OD, and length you need.

Corrosion-Resistant Press-Fit Drill Bushings

These bushings are made of stainless steel, which provides excellent corrosion resistance.

Wear-Resistant Press-Fit Drill Bushings

Made of durable tungsten carbide, these bushings outlast steel.

Made-to-Order Press-Fit Drill Bushings with Head

Choose the ID, OD, and length you need.

Metric Press-Fit Drill Bushings with Head

Even under extreme drilling pressure, these metric bushings won't press through your jig plate. They’re ANSI Type H bushings, also known as headed bushings.

Press-Fit Drill Bushings with Head

A flanged head on these bushings acts as a stop, so they won’t press through your jig even under extreme drilling pressure. They’re ANSI Type H bushings, also known as headed bushings.

Sleeves for Removable Drill Bushings

Avoid wear caused by repeatedly pressing bushings into your jig fixture. Instead, press fit these sleeves into the fixture one time, and then swap bushings with different IDs in and out to change the size of your bit.

Sleeves with Head for Removable Drill Bushings

Use these sleeves to create a permanent base for bushings, so you can swap sizes or replace worn bushings without damaging your jig. Also known as headed liner or HL bushings, they have a flanged head that stops them from pushing through the jig when you drill.

Removable Drill Bushings

Replace worn bushings and quickly change IDs without needing to repeatedly use a lever press. Instead of pressing bushings in and out of your jig fixture, which can cause damage, these bushings slide in and out of sleeves.

Made-to-Order Removable Drill Bushings

Choose the ID, OD, and length you need.

Drill Bushings for Soft Metal and Wood

Serrations on these bushings dig into wood, aluminum, and other soft metals to keep them from spinning while you drill. Also known as jig bushings, they fit inside fixture plates to guide drill bits, counterbores, and reamers.

Drill Bushings for Plastic

Serrations line the sides of these bushings to keep them from spinning while you drill. Also known as jig bushings, they’re pressed or molded into plastic tooling to guide drill bits, counterbores, and reamers.

Secure-Hold Drill Bushings for Plastic

Designed to grip slippery plastic, the knurls on these bushings keep them from spinning while you drill. Their hold is stronger than serrated bushings, so they can withstand more force.

Removable Drill Bushings for Thin Metal

Unlike most bushings, these won’t buckle the material or distort the hole when installed in thin-gauge aluminum and steel fixture plates.
