Profile: Orchard Impex Pvt. Ltd. manufactures nylon inserts & self locking units, castle & slotted nuts, brass bushes & shackle, leveling pads, wheel spanners and axles. Our self-locking nuts provide tight connections that will not loosen under vibrations. All metal self-locking nuts are constructed in two ways. The threads in the load-carrying portion of the nut that is out of phase with the threads in the locking portion is one way. The second way is with a saw-cut top portion with a pinched-in thread. The locking action of these types depends upon the resiliency of the metal. Our wheel spanners are used in automotive industries, which are used for dismantling the punctured tyres. We also provide coupling nuts which are used to connect pieces of threaded rod or other male threaded fasteners.
