From Irwin Vise Grips, these are the original straight jaw locking pliers. Their straight jaws provide maximum contact on flat, square, or hex work, ideal for tightening, clamping, twisting and turning. The screw adjustment at the bottom of the vice grip pliers stays adjusted for repetitive use. Constructed of high-grade heat-treated alloy steel for maximum toughness and durability and featuring a guarded release trigger that quickly unlocks and protects from accidental release. The original and the best.
