Lock-N-Stitch International is a company based out of Turlock California and founded by Garry J Reed in 1990. Lock-N-Stitch International specializes in metal stitching, which is a process where cracks in metal objects caused by stress are repaired. Lock-N-Stitch process of metal stitching uses a series of locks and pins. A pins is a threaded bolt which can provide a pushing or a pulling pressure to the center of the pin. The pins are bolted down in a series along the crack then ground down to a smooth surface then another layer of pins are bolted down between the gaps of the previous pins then are ground down to make a smooth surface. The locks are a strip of metal with circular edges. The two locks are placed perpendicular to the crack and three are placed overlaying each other and then placed into the already driven holes.
