Irwin 2071904 Vise-grip 4 Inch Plier Adjustment Screw

Product Description

The IRWIN 2071904 is a replacement adjustment screw designed for Vise-Grip 4-inch locking pliers. The adjustment screw controls jaw opening width, allowing the plier to clamp securely to a workpiece. Over time, these screws can strip, seize, or lose thread integrity under repeated torque loads. Replacing a worn adjustment screw restores full clamping function without requiring replacement of the entire plier. This part is sold in a package of 5 screws, making it practical for shop restocking or fleet maintenance. Plumbers, pipefitters, electricians, and general mechanical tradespeople who rely on Vise-Grip locking pliers will find this a straightforward service part.

This adjustment screw is a direct-fit accessory for IRWIN Vise-Grip 4-inch locking plier models. It is suited for both shop environments and field repair kits where maintaining a supply of small replacement parts reduces tool downtime. The 5-piece package quantity supports stocking for service vans or tool cribs. This part is appropriate wherever Vise-Grip 4-inch locking pliers are used in residential, commercial, or industrial trade applications.

Installation Notes

Installation of a replacement adjustment screw is a hand-tool service task requiring no power tools or specialized equipment. Ensure the plier is fully open and the old screw is completely removed before threading in the replacement to avoid cross-threading. Inspect the jaw and pivot assembly for additional wear before returning the tool to service. No calibration or torque specification is required beyond hand-tight seating.
