Partially Grooved Dowel Pins

The grooved section secures these pins while the smooth portion is free to act as a pivot or hinge. The grooves pinch shut when installed, creating tension to lock in place. They fit tighter than standard dowel pins and resist pulling from movement and vibration, even in imperfect holes.

For the best fit, drill your hole slightly larger than the nominal diameter shown.

Half Grooved


	Parallel Groove

The most versatile partially grooved pins, these are used in a range of applications, including as rod end linkages, stop pins, and locators. Also known as type H pins.

Zinc-Plated Carbon Steel—These pins withstand occasional exposure to moisture. However, since friction from moving parts can wear away the finish, they're not ideal for wet environments. While not nearly as corrosion resistant as stainless steel, they are stronger and won’t deform under stress.

Parallel Groove—Fit tighter than pins with tapered grooves to stay in place under severe vibration. However, they require more force to insert.

Center Grooved


	Parallel Groove

These pins lock in the middle, leaving two smooth ends free. They're often used to create a T-handle, such as on a valve stem to open and close it by hand. Also known as type E pins.

Parallel Groove—Fit tighter than pins with tapered grooves to stay in place under severe vibration. However, they require more force to insert.

Quarter Grooved


	Parallel Groove

With a longer smooth end than half-grooved dowel pins, these are often used for thicker pivoting parts, such as levers and hinges. Also known as type C pins.

Parallel Groove—Fit tighter than pins with tapered grooves to stay in place under severe vibration. However, they require more force to insert.

Fully Grooved Dowel Pins

With a tighter fit than standard dowel pins, these resist pulling from movement and vibration, even in imperfect holes. Three grooves pinch shut when installed, creating tension to lock in place. Also known as Type A pins.

For the best fit, drill your hole slightly larger than the nominal diameter shown.

Steel

Tapered Groove

Tapered Groove—Easier to install than pins with parallel grooves but less secure in high-vibration applications.

Partially Grooved Dowel Pins with Notch

Slip a spring into the notch at the end of the pin. Often used in automated machinery such as conveyors and robotic arms, the pin anchors the spring in place to create tension between components. The grooved section pinches shut when installed to lock the pin in place. Grooved pins have a tighter fit than standard dowel pins and resist pulling from movement and vibration.

For the best fit, drill your hole slightly larger than the nominal diameter shown.

Half Grooved

Also known as type G pins.

Parallel Groove—Fit tighter than pins with tapered grooves to stay in place under severe vibration. However, they require more force to insert.
