KNIPEX 8" TwinGrip Pliers are designed for easily gripping stripped screws and bolts with both front and side gripping areas. The front jaw design grips even the toughest stripped screws, while the optimized side jaw with opposing teeth provides maximum force when gripping round, square, and hex materials. These pliers feature five push-button adjustments that stay in place once set, and their slim head design allows for working in confined spaces. The large front and side gripping capacities range from 5/32" to 7/8" (4 to 22 mm). The reliable front gripping of flat workpieces is ensured by the three-point system, and a pinch guard prevents operators' fingers from being pinched. The durable construction is due to the box-joint design and the pliers are forged from high-grade chrome vanadium electric steel, oil-hardened, with gripping surfaces featuring special hardened teeth.
