Spring pins compressed due to installation and continuous pressure to the wall of the hole to resist loosening. ASME B18.8.4.M spring Pins are also known as tension pin, slotted spring pin and roll pin.
ASME B18.8.4M Spring Pins are available in a variety of materials, thickness, tolerance, thread, size, design, finishing and many other specifications.
