Also known as clamping pins, these bolts have a collar that slides along the shaft and can be welded in place to hold work and prevent over torquing. The large T-shaped head provides a secure grip for steady tightening. The black-oxide finish provides corrosion resistance in dry environments. Length is measured from the top of the head.
