Hanger Bolts Manufacturer
MT.BOLTS manufactures Hanger Bolts, which are dual-threaded fasteners featuring machine threads on one end and wood screw threads on the other. These bolts are designed to be installed into wood or other soft materials and provide a secure stud for attaching metal components, brackets, or hardware. Hanger bolts are ideal for overhead installations, wood-to-metal fastening, and applications where through-bolting is not feasible. MT.BOLTS supplies hanger bolts in a range of materials, finishes, and standards to meet diverse construction, electrical, and mechanical mounting needs.
