ART 9211 Hanger bolt (solar bolt)

Construction of plumbing stud

Combined screw-screw ART 9211, known as a plumber's stud, has two different threads on each end. On the one hand, there is a metric thread for standard nuts and couplings. On the other hand, there is a "screw" thread for screwing into wood, dowels or plastic. Thanks to this, the product provides reliable fastening between metallic and non-metallic materials. This makes it ideal for installing pipes, radiators, boilers, profiles. The metal is made of carbon steel and is galvanized to protect against corrosion.

Types, sizes, differences of combination screws

ART 9211 plumbing studs come in different lengths — from 60 to 200 mm, with M6, M8 or M10 threads. The differences are in the length of each threaded part. The metric part is intended for installation of equipment, and the screw part is intended for fastening to a wall or base. When choosing the length, take into account the thickness of the mounting element and the depth of fixation. Such screws can be supplied both separately and in a set with dowels, nuts or washers.
