L-4A Levelling Bolt with M12 Thread Size and 100mm Stud Length

The L-4A is a metal leveling foot designed for adjustable height support in industrial frames, machinery bases, conveyors, workstations, and pipe-joint structures. It consists of a threaded steel stem, a hex nut for locking, and a semi-round metal base with a flat-cut edge for close-to-wall or corner mounting. The foot provides stable support on uneven surfaces and allows smooth height adjustment.
