Cross-locking tweezers open when squeezed and close when released, "locking" onto the item being held. This is a set of 6 cross-locking and 2 non-locking tweezers with insulating fiber grips, uniquely shaped to hold round, oval, flat, and square objects. Ideal for holding items such as rings when soldering. Jaws are serrated to provide a firm grip, though they can also be coated in our Tool Magic (see related products below) to prevent scratches. The set includes all 3 of the tweezers in set no. 474-315 and 5 additional styles. For hands-free work, the tweezers can also be installed in our Third Hand (see related products below). All are made from stainless steel and vary in length from 6-1/4" to 8". Furnished with zippered case. Made in India.
