Hardened Undersized High-Speed M2 Tool Steel Rods
- Yield Strength: Not Rated
- Hardness: Rockwell C60 (Very Hard)
These rods, also known as drill blanks, have an undersized diameter for machining your own jobbers'-length drill bits. They're hardened for increased abrasion and impact resistance. M2 tool steel offers a nice balance of wear resistance and machinability. It has a high molybdenum content, which allows it to maintain sharp cutting edges even at elevated temperatures.

Linear Motion Shafts
Smooth, hard, and wear resistant, these shafts work with linear bearings to reduce friction in manual and automated systems, such as those found in packing, machine tool, and material handling operations. All are turned, ground, and polished to tight diameter and straightness tolerances.
Stainless steel shafts are more corrosion resistant than steel shafts; however, they’re not as hard as steel shafts and can be more difficult to machine. 17-4 PH stainless steel shafts are more corrosion resistant than 400 series stainless steel shafts, but they’re not as hard or as wear resistant.
Surface smoothness—The lower the microinch value, the smoother the finish and the less friction and wear it will cause on the bearing.

Rotary Shafts
Combine these general purpose drive shafts with gears, sprockets, and bearings to transmit rotary motion. All are turned, precision ground, and polished to meet tight diameter and straightness tolerances. This means these shafts evenly distribute loads, reduce vibration, and improve accuracy and stability.
Stainless steel shafts are more corrosion resistant than steel shafts but more difficult to machine. 316 stainless steel shafts are the most corrosion resistant stainless steel shaft.
Shafts with chamfered edges reduce damage to bearings, housings, and other components during installation.

Dowel Pins
Use dowel pins as pivots, hinges, shafts, jigs, and fixtures to locate or hold parts. For a tight fit, your hole should be equal to or slightly smaller than the diameter shown. Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.
Steel pins are the strongest dowel pins. Steel pins are precision ground except for 1/32" diameter pins. Stainless steel pins are more corrosion resistant than steel pins. Pins that are passivated offer added protection against corrosion and oxidation. Stainless steel pins are precision ground except for 1/64" diameter pins. 18-8 stainless steel pins offer a balance of strength and corrosion resistance. They may be mildly magnetic. 316 stainless steel pins have the best corrosion resistance of our stainless steel pins. They may be mildly magnetic. 416 stainless steel pins are more wear resistant than other stainless pins, but not as corrosion resistant. They are magnetic.
Some pins meet material and dimensional standards set by ASME, Mil. Spec., DIN, or ISO. DIN 6325-m6 is functionally equivalent to ISO 8734, with slight differences in hardness and length tolerances. ISO 2338-m6 is functionally equivalent to DIN 7, but the ends are chamfered instead of rounded.

Undersized Dowel Pins
Slip these pins in and out during maintenance or prototyping—they’re undersized to make alignment easier. Unlike standard pins, which fit tightly inside holes, these are designed to give you some wiggle room. Chamfered ends make them easier to insert. The breaking strength listed is double shear, which is the amount of force required to break a pin into three pieces.
18-8 stainless steel pins can be used in wet and humid environments without rusting, but they are not as strong as steel.
All metric pins meet ISO 2338-h8, which means they adhere to international standards for dimensions and tolerances.
For technical drawings and 3-D models, click on a part number.
Full-Groove Dowel Pins
Grooves run the full length of these pins for a firm hold that won't spin. Use them in place of standard dowel, spring, and taper pins to fasten parts. The three grooves pinch shut when pressed into a hole, creating tension to lock pins in place. For the best fit, the hole should be equal to or slightly larger than the diameter shown. The ends are chamfered for easy insertion. Breaking strength is measured as double shear, which is the force required to break a pin into three pieces. Also known as type A pins.
Pins with tapered grooves are easier to install than pins with parallel grooves, but more likely to loosen from vibration. Pins that meet ISO 8744 comply with international standards for tapered-groove metric dowel pins.
Zinc-plated steel pins have good strength and some corrosion resistance.

Center-Groove Dowel Pins
Center-groove pins are often used in place of clevis pins or to create T-handles. The grooves pinch shut when pressed into a hole, creating tension and holding the pin in place. The grooved center locks pins in position, while the smooth ends act as a pivot. For the best fit, the hole should be equal to or slightly larger than the diameter shown. The ends are chamfered for easy insertion. Pins are made of zinc-plated steel for good strength and some corrosion resistance. Breaking strength is measured as double shear, which is the force required to break a pin into three pieces. Also known as type E pins.

Half-Groove Dowel Pins
These pins make good hinges or pivots. The grooves pinch shut when pressed into a hole, creating tension and holding the pin in place. The grooved half locks pins in position, while the smooth half acts as a pivot. For the best fit, the hole should be equal to or slightly larger than the diameter shown. The ends are chamfered for easy insertion. Pins are made of zinc-plated steel for good strength and some corrosion resistance. Breaking strength is measured as double shear, which is the force required to break a pin into three pieces. Also known as type H pins.
Tapered pins are good when part of the assembly must be a free fit.
Reverse-tapered pins are useful when the ungrooved portion will act as a stop or handle.
