Thread Cleaning Tap - 7/16-14

The ARP Thread Cleaning Tap – 7/16-14 is a precision steel tool designed for mechanics and engine builders who require reliable fastener preparation. This tool is ideal for restoring classic engine blocks, rebuilding high-performance cylinder heads, or servicing damaged bolt holes.

Engineered to remove buildup, corrosion, and debris from existing threaded passages, this thread chaser does so without altering the original thread geometry. Made from hardened steel, it ensures durability through repeated use on cast iron and aluminum surfaces, with cutting flutes optimized to clear chips efficiently and restore threads to near-original condition.

This tool is beneficial for engine assemblers, machine shops, and DIY builders preparing engines for rebuild or assembly. It can be used in a hand tap wrench or power drill at moderate speeds to chase out light rust, thread sealant residue, or minor corrosion before installing ARP bolts or OEM fasteners.
