High-Quality ARP 912-0011 11mm x 2.00 Thread Cleaning Tap: A Must-Have for Precision Thread Maintenance Review

Thread Cutter is great for cleaning cylinder head bolt threads on LS and LT Chevy engines. The correct torque must be provided.

Fast shipping, proper packaging. A high quality ARP tool at a great price. DO NOT put the head on the LS motor without cleaning the threads! As with any thread cleaning, take your time and do not use force. Clean threads = greater chance of more consistent/accurate torque readings.

Bought to clean the cylinder head bolt holes on my 5.3 liter engine before assembly. I'm grateful I spent the money. He pulled some Loctite and "goo" out of the block. The assembly went well. I bought a smaller one for exhaust system bolts, small cap bolts and rocker arm shaft bolts. Thanks again for pulling the shit out. (8x1.25?)

This tool works very well. You'll be surprised how much crap you can pull out of these holes. I strongly recommend protecting the cylinders and cooler bags from dirt. I use this tool in conjunction with a brake cleaner. With LS engines it is very important that they are clean or the screws are hydraulic. Spend your money on the right tool and get it done before you try to break your head.

I didn't realize the head bolts on my 5.3 LS V8 trucks were so unwieldy or I would have taken more time to find a cheaper tapping tool Find. Unfortunately I didn't have much time and needed to assemble the motor, so I gritted my teeth and bought the thing. The cost of a hunter that I will literally use ONCE is stupid. I am a fan of ARP products and installed a head bolt kit on my truck while at work. This stalker worked great and I had no problems with it, but ARP needs to get really crazy with
