These 5/8" baby pins were designed to work in any/all of the nine available positions on the MP-9 clamp. The stainless steel thread (3/8-16) is encased by an exterior sleeve that has two register points (notches) at the base. These notches allow you to lock on to the roll-pins which exist at each of the nine locations...and once tightened, the roll-pin will not let the pin twist in either direction. The top of these pins were designed to be easily tightened by a 9/16" wrench.
- This pin also works with the Big Bite Baby clamp.
