FULL-TORQUE® - Thread Replacement
FULL-TORQUE® thread repair inserts provide a completely new solution to stripped and cracked bolt holes. No other thread repair method even comes close to the strength and durability you will realize when you install our inserts. FULL-TORQUE® thread inserts have a patented external thread style called Spiralhook® . This is a revolutionary new concept that makes our thread repair inserts the very best in the world. Cracked bolt holes are now easily repaired and strengthened. Head bolt holes, main bearing bolt holes, starter motor bolt holes, the uses are endless. When a FULL-TORQUE® thread insert is installed into a cracked bolt hole in cast iron, the crack is automatically drawn together and reinforced by the radial drawing ability of the Spiralhook® threads on the outside of the insert. All other thread designs create radial spreading force when tightened. This eventually leads to cracked and stripped bolt holes in machinery parts. Our spark plug thread repair inserts will outlast the engine and won’t come out the next time the plugs are changed. We have the only spark plug inserts for aluminum cylinder heads that are made of aluminum and are hard anodized for strength and durability. No other thread insert can create a liquid and pressure tight seal between the thread insert and the surrounding metal. FULL-TORQUE® inserts can withstand 3000 psi hydraulic pressure seal on the external threads. We have the only true pipe thread repair inserts capable of creating a better than new seal on both threaded surfaces. Our motto is “Fix it and Forget it”. Coil type inserts can only fix a simple stripped hole and tend to be temporary at best. All other solid and key locking threaded inserts are made from very soft steel and have incomplete external threads. All other types and styles of thread repair inserts have a reputation for coming loose and backing out the next time the fastener is removed. That won’t happen with FULL-TORQUE® thread repair inserts and plugs and they look really good after they are installed. Many US engine manufacturers use FULL-TORQUE® to solve the most demanding bolt hole failure problems in there remanufacturing operations. We also use the same size tap for many different internal thread sizes. Our FT4 size will install 10mm x 1.5, 11mm x 1.5, 3/8-16, 3/8-24, 7/16-14, and 7/16-20 inserts so they actually cost less than all other inserts when you stock a variety of sizes. Absolutely the best thread repair insert system ever developed. The secret is in the patented external threads that pulls the surrounding metal into the threads of the insert and adds strength to the part being repaired. It is now very easy to make bolt holes stronger than the bolt or stud, even in aluminum.
Nothing else can compare to the incredible results you will have using FULL-TORQUE® thread inserts. We have a style that will solve your bolt hole problem no matter how tough it is.
Other styles such as solid and pre-drilled plugs for repairing various other problems such as holes that have been drilled in the wrong place or oversized. Say goodbye to damaged bolt hole problems forever!
It’s not a crack free world..... |
Cracked holes, stripped holes, weak holes, holes with broken taps or easy-outs. Holes that need to be sealed pressure tight. Spark plug holes, pipe thread holes and holes that have been drilled in the wrong locations. 
Bolt holes like this that connect with the water jacket of an engine block need to be sealed water tight. The FFB style insert can easily seal a damaged bolt hole like this. In certain cases like this will require some crack repair with our CASTMASTER® stitching pins to complete the repair and to seal the leaks completely.
