Screw-in stud M12x1,5 80MM

Screw-in studs are design for cars that have wheels originally installed with bolts. The studs have a double-ended thread -shorter end is screwed into the existing threaded bolt hole in the hub and longer one protrudes beyond the hub. When we install wheels, we put them on the studs and fasten with nuts. This is easier and faster way than installing with bolts. For this reason such studs are often used in motor sports (in cars taking part in rallies). Screw-in studs can be used in combination with slip-on spacers.
