AJAX Tools Hinge Pin Driver Diameter

The AJAX Tools Hinge Pin Driver line gives technicians a purpose-built way to remove and install hinge pins on doors, tailgates, and equipment panels. These pneumatic bits, also called hinge pin punches or zip gun hinge pin drivers, are made to be used with an air hammer. They drive stubborn, corroded, or painted-in pins out cleanly. Each driver is offered in different pin diameters to suit different hinge pin sizes.

Key Features:

• Forged alloy steel construction: Built for repeated impact use in collision repair, fleet maintenance, and industrial work.
• Turn-type .401 shank: Fits standard .401 air hammers and zip gun style tools.
• Precision driver tip: Directs force straight onto the pin, which helps prevent slipping and protects hinges, doors, and frames.
• Compact working length: Gives access in tight spaces such as door jambs and cab doors.
• Made in the USA: AJAX Tool Works is a respected American maker of forged specialty tools and accessories.

Whether you are replacing hinges, aligning doors, or freeing seized hardware, the AJAX Tools Hinge Pin Driver line helps you finish the job faster and with less risk of damaging surrounding components.
