Headless bolts

Headless bolts

Our headless bolts such as stud bolts, threaded rods, threaded pins, grub screws and screw bolts are specially developed to meet the demanding requirements of industry, such as mechanical engineering, apparatus engineering and the automotive industry. Through precise manufacturing and the use of first-class materials, we offer you solutions that are convincing in both standard and customized designs.

Stud bolts are ideal for applications where frequent loosening and fastening is required. They are characterized by the absence of a forged head and have a thread at both ends. The continuous shank between the threads has the same diameter as the thread. With these screws, a distinction is made between the nut end, which is intended for the fastening nut, and the screw-in end, which is screwed into the corresponding component.

A major difference between DIN threads and screws with heads lies in the determination of the nominal length. While the total length up to the flat surface is specified for threaded parts according to DIN and cap screws, the nominal length for stud bolts refers to the area without phase (from the first load-bearing thread).
