These Bench Dogs are made from solid brass. They have a 1/2" shaft, and the head is 3/4" square. You have the option of different head heights ranging from 1mm to 3/4" thick. Thinner head heights are ideal when working with thin wood, such as shop sawn veneer. W
One edge of the dog head is slightly curved and angled at 2 degrees to allow it to bite into the wood being held.
