Frequently Asked Questions

What is a MAYHEW PRO pin punch used for?

A MAYHEW PRO pin punch is used to drive out pins, dowels, and fasteners from assembled components in industrial maintenance, machining, and repair applications. Its flat tip and tapered shank concentrate force precisely, making it essential for disassembly tasks across automotive, manufacturing, and metalworking sectors.

What are the specifications of the MAYHEW PRO 21503 pin punch?

The MAYHEW PRO 21503 pin punch has a 5/16 in tip diameter, 7/16 in hexagon shank width, 3 1/2 in taper length, and 8 in overall length. It is made of steel, SAE-sized, and compliant with ASME B107.410-2008. The hexagon shank prevents rolling on work surfaces.

Where to buy a MAYHEW PRO pin punch worldwide?

3G Electric supplies the MAYHEW PRO pin punch worldwide. We interpret your demand, source the correct SAE punch, and handle full logistics and customs clearance for delivery to any global location. Contact us for availability and lead time on this and other industrial tools across 14 departments.

How to select the right pin punch size?

Select a pin punch with a tip diameter slightly smaller than the pin you are driving to avoid damaging the workpiece. For the MAYHEW PRO 21503, the 5/16 in tip suits pins of similar or slightly larger diameter. Always match the shank shape to your hammer type; hexagon shanks offer better grip and stability.
