Diamond Tungsten Pins - 100 Pack

Each resealable tube contains 100 x 4.5mm pins and a #17 drill bit. 

Diamond is the New label, same tough tungsten pin. 

These pins with a tapered shaft are fantastic for providing traction on asphalt, concrete, ice, or rocky terrain. These pins are so durable, resetting is possible.

Once the hole is drilled, the pin is driven into the preferred depth. A tapered shaft allows for excellent seating as it tightens as it is driven.
