knipping verbindungstechnik fastener studs are a type of fastener used in sheet metal, thin plates, chassis, and cabinets. During connection, one end must be screwed into a part with an internal threaded hole, while the other end passes through a part with a through-hole, and then a nut is tightened, firmly connecting these two parts into a single unit. This type of connection is called a stud connection and is also a detachable connection, mainly used when one of the connected parts has a large thickness, requires a compact structure, or is frequently disassembled, making bolt connections unsuitable. The press-fit nut stud has a hexagonal shape at one end and a cylindrical shape at the other, with a relief groove between the hexagonal edge and the cylindrical section. Its interior features internal threads. By using a press to insert the hexagonal head into a pre-drilled hole in the thin plate, plastic deformation occurs around the hole's perimeter. The deformed material is squeezed into the relief groove of the press-fit nut stud, securing it tightly to the thin plate and forming an effectively fixed internal thread on the thin plate.

knipping verbindungstechnik fastener applications

A stud refers to a cylindrical fastener with threads on both ends. It is used in main bodies of large equipment where accessories need to be installed, such as sight glasses, mechanical seal seats, gearbox frames, etc. In these cases, one end of the stud is screwed into the main body, and after installing the accessory, a nut is placed on the other end. Studs are used when the thickness of the connected bodies is substantial, and double-ended bolts serve the purpose of preventing loosening. In actual work, external loads such as vibration, changes, and high-temperature creep of materials can reduce friction. At certain moments, the normal pressure in the threaded pair disappears, resulting in zero friction, which causes the threaded connection to loosen. If this happens repeatedly, the threaded connection will become loose and fail. Therefore, anti-loosening measures for studs must be applied according to different usage environments. They are widely used in power, chemical, oil refining, valves, railways, bridges, steel structures, automotive and motorcycle parts, machinery, boiler steel structures, cranes, large-span steel structures, and large buildings.

Stud welding saves time and costs by eliminating the need for drilling, punching, threading, riveting, tapping, and finishing in all structural applications. It continuously expands the application potential of structural design, offering high current capacity and shallow penetration depth. Therefore, it can be welded to very thin sheets. Workpieces for stud welding must be welded from one side. All-position welding is possible; with the aid of extensions, welding can be performed on restricted vertical partitions. Due to the short welding time and minimal post-weld distortion, no finishing is required. Since the welded structure does not require drilling, leakage is avoided. The joint can achieve very high strength, meaning the joint strength of stud welding exceeds the strength of the stud itself. How to install double-ended studs: Good economic efficiency. The advantage over other welding methods lies in the welding power. For mass-produced workpieces, standard studs are low-cost, and stud welding offers high quality reproducibility and a low scrap rate.

knipping verbindungstechnik fastener maintenance

During each maintenance operation, inspect the newly replaced studs and other newly replaced accessories. Focus the inspection on the head and guide portion of the stud. Strictly check every part of the thread for cracks or dents, and examine the stud's thread profile for any changes. Check for abnormal pitch; if any abnormalities are found, the stud must not be used. When installing the connecting rod cap, use a torque wrench. Tighten strictly according to the specified standard; the torque must not be excessive or insufficient. Also, ensure the selection of bolts and studs from matching manufacturers. Therefore, proper stud maintenance should be carried out routinely. Problems may arise due to prolonged mechanical friction on the studs. When issues occur, remove the engine oil pan and carefully inspect the condition of the engine bearings. Check whether the clearance between the bearings is excessive; if the clearance is too large, replace them promptly.
