Hot-Hed® International's Lock-Well Nuts™ Anti-Tamper Fastener System are an innovative, secure, wellhead locking system. Engineered as a specialized anti-theft fastening device to prevent unauthorized access to wellheads and flanges, they replace conventional studs and nuts with hardened, tapered fasteners that are impossible to remove using conventional methods.
Hot-Hed®'s Lock-Well™ nuts have a hardened coating at the point where they are exposed, thus preventing anyone from cutting through the stud between the mating faces of the flanges. Lock-Well™'s hardened nuts also prevent any type of tool from cutting into them.
Although our Lock-Well Nuts™ are easy to install using the Hot-Hed® Tensioner and High Pressure Pump, removal is impossible without Hot-Hed®'s Tensioner. Standard wrenches just slip off the tapered walls of our Lock-Well Nuts™.
