ARP Thread Cleaning Tap, M12 (12 x 1.75mm)

Brand: Automotive Racing Products (ARP)

Dirty threads can cause a variety of problems, from incorrect torque preload to ineffective thread locking compound. Professional engine builders chase all female threads prior to assembly, even with brand-new parts.

Thread cleaning (chasing) taps are the proper way to clean and dress female threads. Instead of cutting new threads, these special tools are designed to remove foreign matter and to straighten the existing threads if necessary.

This size is designed to clean female M12 (12 x 1.75mm) metric threads.
