DIN 88149 Hanger Bolt Dimensions by Material, Finish and Size

Hanger bolts are headless,  double-ended suspended bolts, that have a tapered lag-screw type thread at one end, and a machine screw type thread at the other end. The lag screw threaded end is screwed into wood and the other end can accept a nut. So Hanger Bolts are mainly wood to metal fasteners, while Dowel Screws, which have screw-type threads on both ends, are for wood to wood fastening.

Hanger Bolts are headless bolts with tapered lag or wood screw threads at one end and machine screw threads at the other. Hanger bolts are mostly used for connecting wood to metal. Headless hanger bolts or hanger screws are other names for these bolts. Hanger bolts can be used with or without a nut, and they can be inserted into a machine tapped hole. With unified national coarse pitch (UNC), fine pitch (UNF), fixed pitch (UN), and ISO metric thread profiles, hanger bolt measurements are described in both metric and imperial sizes. These are manufactured in a variety of materials and according to ASTM requirements.
