Description
The Mayhew 1/2” x 8” Pin Punch (21017) is a specialized hand tool designed for precise and efficient removal of pins and keys that have already been loosened. Its primary function is to complete the extraction process after a solid punch has initiated movement. Crafted in the USA, this punch features a durable black oxide finish that provides an additional layer of protection against rust and corrosion, extending the tool’s lifespan and maintaining its appearance even with frequent use. The 1/2-inch pin width is ideal for a range of common pin sizes, while the 8-inch overall length offers good reach and leverage for various applications, from automotive work to machinery maintenance and general repair tasks. The hexagonal body design ensures a secure grip during use and prevents the tool from rolling on flat surfaces.
