3/64" Shafts | McMaster-Carr

Pair with gears, sprockets, and bearings to transmit rotary motion. Turned, ground, and polished to tight tolerances, these shafts reduce vibration, evenly distribute loads, and improve accuracy.

Highly Corrosion-Resistant 316 Stainless Steel—More corrosion resistant than 303 and 304 stainless steel shafts. They stand up to salt water and harsh chemicals, such as bleach, chlorine, and phosphoric acid.

Linear Shafts

Pair with linear bearings and shaft supports to create smooth, precise motion. These linear shafts are turned, ground, and polished to tight tolerances and hardened to resist wear.

Corrosion-Resistant 17-4 PH Stainless Steel—More corrosion resistant than 420 and 440C stainless steel, but not as hard or wear resistant.

Surface Smoothness—The lower the microinch value, the smoother the finish and the less friction it will cause on the bearing.

Dowel Pins

Precisely align machine parts and prevent movement during assembly. These dowel pins are machined to tight tolerances and have a uniform diameter for a snug fit. They can also be used as a pivot, shaft, or hinge to join moving components. Since dowel pins can be hard to remove, they are best suited for permanent fixtures that don't require frequent adjustments or disassembly.

Steel

High-Strength Alloy Steel—Our strongest, most wear-resistant pins, these won't bend or break from vibration. Use them for high-stress applications, such as mounting and aligning hydraulic cylinders and injection molds. They perform best in dry environments since moisture will cause them to rust.

Material Certificate—Pins include a report with a traceable lot number and a description of their chemical, physical, and mechanical properties.

Corrosion-Resistant Stainless Steel About Corrosion-Resistant Stainless Steel

18-8 Stainless Steel—The choice for wet and outdoor environments. In addition to resisting rust, these pins also withstand mild chemicals such as cleaners and degreasers. They are strong enough to join most components but won't withstand extreme stress and vibration as well as steel.

Highly Corrosion-Resistant 316 Stainless Steel—Our most corrosion-resistant pins, these hold up in just about any environment. They won't degrade from exposure to weather, salt water, and most chemicals. Like 18-8 stainless steel, they're strong enough to join most components but won't withstand stress and vibration as well as steel.

High-Strength Machinable 416 Stainless Steel—These pins hold their shape under stress and friction from moving parts. In addition to being the strongest stainless steel alloy, 416 is also the most machinable, so you can shape these pins to fit your hole. However, they are the least corrosion-resistant stainless steel option.

Plastic Dowel Pins

Assemble circuit boards and other electronic parts with dowel pins that insulate against stray current. These pins prevent short circuits and electromagnetic interference (EMI) that can harm performance and cause malfunctions. They’re also lighter than metal pins if you need to reduce weight in prototypes and moving assemblies. Dowel pins are machined to tight tolerances and have a uniform diameter for a snug fit. Since they can be hard to remove, they are best for fixtures that don't need to be adjusted or taken apart frequently.

Plastic

Wear-Resistant Acetal—Slippery and wear resistant, these pins make excellent pivots. They're often used for automated machinery and other moving parts that create a lot of friction. They also prevent short circuits better than PEEK and polycarbonate plastic.

Impact-Resistant Polycarbonate—Our most impact-resistant plastic pins, these resist cracking when inserted into tight holes. They are also clear to be less noticeable in your assembly.

High-Strength PEEK—The closest alternative to metal pins, these offer the best strength to stand up to stress and vibration. In addition, they won't degrade or lose their shape when exposed to high heat. They aren't very impact resistant, however, and may crack if inserted too forcefully.

Tight-Tolerance Ultra-Heat-Resistant M42 High-Speed Tool Steel Rods

Machine saw blades, end mills, and other cutting tools that stay hard and sharp at top speeds and temperatures. M42 runs faster and hotter than other grades of high-speed tool steel, so it slices through material as tough as titanium without softening or wearing down. Precision ground and held to a strict tightness tolerance, this steel is all set to turn in your lathe. Also known as cobalt steel.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

Ultra-Formable 260 Brass Rods

The most formable brass alloy we offer. With its high copper content and little to no lead, 260 is so soft you can bend it at room temperature. It's often shaped into ammunition casings, radiator components, and decorative door hardware. Also known as cartridge brass.

High-Temperature Ultra-Dense Tungsten

Rods

Ultra dense for use as electrodes, furnace support pillars, and screws and bolts, these chemically pure tungsten rods withstand greater heat than other high-temperature metal, such as molybdenum. You can also use them in applications where voltage increases may cause temperature spikes that other metal can’t handle. These rods won’t deform in high heat, so they last longer than other metal. However, they’re harder to machine than more ductile tungsten alloys. These rods won’t corrode from chemicals or weather.
