Leading Casting Repair Expert Unveils Revolutionary Thread Repair Technology
Lock-N-Stitch CEO announces another first for the casting repair industry - Full-Torque(TM) Thread Repair technology
TURLOCK, Ca., February 17, 2004 -- Lock N Stitch Inc, a national leader in the casting repair industry, has developed another state-of-the-art repair solution to add to its exclusive product line. Full-Torque(TM), a high tech thread repair system is based on the Spiralhook(TM) thread geometry developed by Lock-N-Stitch CEO, Gary Reed. Designed to restore both the needed strength and new threads simultaneously, his latest invention promises to change the way the industry repairs cracked bolt hole threads. A 30-year industry veteran, Reed holds more patents in the field of casting repair than anyone else in the world, including 19 in the U.S. He founded his company in the early 1970s and his successful line of metal stitching products have since been used by industry giants and the military including General Motors, Caterpillar, Navistar, Dresser-Rand, Mack Truck, the United States Army and in the U.S. Capitol Dome.
"This is, by far, our most revolutionary technological advancement to date," says Reed. "Full-Torque is drastically different from standard methods, which are often ineffective. With this product, casting repair professionals now have a solution that not only effectively repairs, but makes the bolt hole better than new," he added.
Cracked bolt holes are difficult to repair because of the spreading force exerted when the bolt or stud is torqued. According to Reed, standard thread repair inserts and coils can make the problem worse by removing material around the threaded hole. Reed's Full-Torque design increases the strength of the casting when the bolt or stud is torqued into the insert, it pulls up on the insert, increasing the load on the Spiralhook threads, and increasing the radial drawing force of the threads. This system will contain the crack and prevent future damage while maintaining full clamping load.
Full Torque-Thread Repair is now available in most common inch and metric sizes. They are easy to install and will not come out. To learn more about available sizes, special applications such as tapered pipe and spark plug thread repair visit: http://www.locknstitch.com/inserts.htm.
