The Snap-on P-Series Cutting Pliers feature an added staked screw design to relieve foreign object damage concerns. The pliers also have an internal torsion spring that returns the pliers to the open position and keeps them grip-friendly and ready to work. Because the plier joints are precision-ground, opening and closing friction is reduced and the tool operates smoothly without lubrication. The tool frames are heat-treated and made with a hot-forged technology that aligns the grain structure of the proprietary alloyed steel to follow the profile of the shanks. The pliers stay sharp through 200,000 cycles.
