What People Are Saying

Terox is a company I will recommend.

I cannot say enough good things about this product and the staff behind it. More than a tap, the support behind it is second to none. Terox is a company I will recommend with out a doubt.

Bill P

Working as expected!

Everything is working as expected and we are happy with the kits

Joe, Down Time Services

Impressed with the quality

The finished repair turned out very well, and I was impressed with the overall quality and performance of the Terox repair kit.

Emily, Carter Machine

Love the pulling power

I love the way these HP2S pins feel when they are pulling into the thread. They feel like they are a bigger diameter with the more coarse thread than the original C2 from Lock N Stitch.

Scott, Love Machine Co

Pins go in perfectly

The pins are going in perfectly.  I like the thread design with the more coarse thread.  They go down tight.
