Precision Threaded Hole Repair Services

LOCK-N-STITCH Inc.'s revolutionary thread repair inserts leverage our new and patented technologies to facilitate in-shop and on-site installation. These thread repair inserts offer a range of benefits. For example, they fit flush to the surface and withstand high-pressure environments in addition to providing higher torque values than the actual fasteners that are torqued into them.

Inserts are available in female NPT threads up to 1.5", and up to 4" for inner-diameter thread sizes. Custom sizes can also be manufactured to suit a variety of applications. Solid plugs are also available to provide customers with the ability they need to create their own thread inserts for emergency situations that require non-standard threads. To suit specific applications, thread inserts are offered in several material types, such as 1144 stress-proof steel, hard-anodized aluminum and heat-treated steel with a hardness of 40 Rc.
