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.

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.
Pins with parallel grooves fit more tightly than pins with tapered grooves, so they’re less likely to loosen from vibration. However, they require more force to insert. Pins that meet ISO 8740 comply with international standards for parallel-groove metric dowel pins.
Zinc-plated steel pins have good strength and some corrosion resistance.
18-8 stainless steel pins offer a balance of strength and corrosion resistance. They may be mildly magnetic. Pins are passivated for added protection against corrosion and oxidation.

Round Head Full-Groove Dowel Pins
A head gives these grooved pins a finished appearance and distributes loads over a wider area than headless pins. The 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 diameter (A). The end is chamfered for easy insertion.
Pins meet ASME B18.8.2 specifications for material and dimensions. They're made of zinc-plated steel for good strength and some corrosion resistance.

Quarter-Groove Dowel Pins
Quarter-groove pins are well suited for hinges or pivots. The grooves pinch shut when pressed into a hole, creating tension and holding the pin in place. The grooved end locks pins in position, while the smooth portion 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 C pins.

Half-Groove Dowel Pins with Notch
These pins are commonly used as anchors for tension springs. The grooved half locks pins in position, and spring ends fit in to the notch. The grooves pinch shut when pressed into a hole, creating tension and holding the pin in place. For the best fit, the hole should be equal to or slightly larger than the diameter shown. The ends are rounded 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 G pins.
