genoma fasteners Germany genoma model genoma price

genoma 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, securely joining the two parts into a single unit. This type of connection is called a stud connection, which is also a detachable connection, primarily used when one of the connected parts has greater thickness, requires a compact structure, or frequent disassembly makes bolted connections unsuitable. The press-fit nut stud has a hexagonal shape on one end and a cylindrical shape on the other, with a relief groove between the hexagonal edge and the cylindrical section. Its interior features internal threads. By using a press to force the hexagonal head into a pre-drilled hole in the thin plate, plastic deformation occurs around the hole's perimeter. The deformed portion is forced into the relief groove of the press-fit nut stud, securing it tightly to the thin plate and forming an effectively fixed internal thread.

genoma fastener applications

A stud refers to a cylindrical fastener with threads on both ends. It is used in large equipment where accessories such as sight glasses, mechanical seal seats, and gearbox frames need to be installed. In such 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 connected bodies have substantial thickness. Double-ended bolts serve the purpose of preventing loosening. In actual operation, 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 slack and fail. Therefore, anti-loosening measures must be implemented. Studs are applied in various environments and are widely used in power generation, chemical industry, oil refining, valves, railways, bridges, steel structures, automotive and motorcycle parts, machinery, boiler steel structures, cranes, large-span steel structures, and large buildings.

genoma fastener installation

Studs save time and costs as all structural components do not require drilling, punching, threading, riveting, screwing, or finishing steps, continuously expanding the application potential of structural design. They support high current and have minimal penetration depth, allowing welding onto very thin plates. Stud welding must be performed from one side of the workpiece. It can be welded in all positions, including restricted vertical partitions, with the help of extenders. Due to the short welding duration and minimal post-weld distortion, no trimming is required. Since the welded structure does not require drilling, there is no risk of leakage. The joint can achieve very high strength, meaning the strength of the stud weld joint exceeds that of the stud itself. How to install double-ended bolts offers good economic benefits compared to other welding methods, particularly in terms of welding power. For mass-produced workpieces, standard studs are low-cost, and stud welding provides high quality reproducibility and lower scrap rates.

genoma fastener maintenance

During each maintenance session, newly replaced studs and other components should be inspected. Focus on the head and guiding portion of the stud, strictly checking each part of the thread for cracks or indentations. Also examine the tooth shape of the stud for any changes. Check if the pitch is abnormal; if abnormalities are found, the stud must not be used. When installing the connecting rod cover, use a torque wrench. Tighten according to specified standards, ensuring the torque is neither too high nor too low. Additionally, select matching manufacturer bolts and studs. Regular maintenance of studs is essential. Prolonged mechanical friction can cause issues with studs. When problems arise, remove the engine oil pan and carefully inspect the condition of the engine bearings. Check if the gap between the bearings is excessive; if so, replace them promptly.
