Fully Grooved Dowel Pins with Rounded Head
The domed head creates a finished appearance, so these pins are often used to attach brackets, knobs, and machine plates. The grooves pinch shut when you press pins into a hole, creating tension to lock them in place.
For the best fit, drill your hole slightly larger than the nominal diameter shown.

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.
