Mayhew Pin Punch 1/8 in Tip 5/16 x 8 in Black 21500

Pin punch for pin removal

The Mayhew 21500 is a hand-held pin punch designed for driving and removing pins in automotive and mechanical work. Its 1/8 in tip suits small pin diameters commonly found in brake, suspension and linkage assemblies. The tool is sold new and meets or exceeds ASME standards for professional use. It targets technicians and DIYers who need a dedicated pin-driving tool.

Heat noise and power draw

As a non-powered hand tool the punch generates no heat, noise or electrical draw during operation. The black oxide finish resists corrosion without requiring lubrication or external energy input. Users rely solely on hammer strikes so physical effort determines the work rate. There are no thermal or acoustic factors to manage in normal use.

One-piece steel build and tether point

The punch uses a one-piece steel construction with a 5/16 in hex body that resists bending under repeated impact. A black oxide coating adds surface hardness and reduces glare under shop lighting. A tether-capable feature allows attachment to a lanyard for drop prevention when working at height. The single-piece design eliminates loose heads or handle separation over time.
