Kerckhaert Tungsten Pins - 100 Pack

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

These pins 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 out, the pin is then driven into the preferred depth. A tapered shaft allows for excellent seating as it tightens as its being driven.
