Used to increase strength across metal cracks. When used in combination with LOCK and C series pins, it allows for high-strength and permanent repairs.
■□■A completely new metal crack repair that is not welding■□■ The strength reinforcement material "LOCK" is made of "4130 steel" and is heat-treated to maintain a tensile strength of 175,000 psi (12,200 kg/cm²). LNS Lock is manufactured by cutting with EDM wire for precision, making it superior to Roll Type and Punch Type locks in all aspects. Since the Lock cannot be bent, it cannot be applied to the corners of uneven areas and is only usable on flat surfaces. For more details, please contact us.

basic information
【Features】Metal crack repair is handled by our company. ○ It is used to increase strength across the crack. ○ A special drill jig is used for precision pattern machining of holes where the lock is inserted. ○ All LNS Locks have the function of pulling the crack areas together, which has the capability to prevent the crack surfaces from spreading rather than merely bringing them closer together. ○ We use the largest possible lock in areas where high strength is required. ○ Due to the inability to bend, it cannot be applied to the corners of uneven areas and is limited to flat surfaces; therefore, CASTMASTER Pins are used for curved areas, while locks are used for flat areas. ○ When using locks and CASTMASTER Pins together, a high-strength, permanent repair is possible. ● For more details, please contact us.

Company information
<We provide nationwide support> LNS JAPAN Co., Ltd. is an engineering company that performs maintenance and repairs of equipment and metal structures in various industries (such as petroleum, chemicals, power generation facilities, ships, heavy machinery, automobiles, steelmaking, etc.) using the METAL STITCHING method. Currently, most of the critical equipment used across industries is facing a challenging situation for new capital investment due to the global economic downturn. In Japan's industries, welding technology, which is widely used for metal repairs, has recently led to significant damage to many pieces of equipment and critical assets due to a shortage of skilled craftsmen and inexperienced welding repairs, with many cases worsening. Our company is the only certified company in Japan and is committed to continuous technological development in collaboration with our parent company, LOCK-N-STITCH INC, which continues to leap and grow as a global enterprise. We promise to ensure thoroughness for extending the life of equipment and providing high-quality and rapid maintenance by avoiding issues such as deformation from heat and secondary cracking, which have been problems with traditional welding repairs, while also achieving shorter construction periods and lower repair costs. For repairs where you want to avoid using fire or where time is limited, please contact LNS JAPAN.
