federal mogul 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, which 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 an undercut groove between the hexagonal section 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, and the deformed material is squeezed into the undercut groove of the press-fit nut stud, securing it firmly to the thin plate and forming an effectively fixed internal thread on the thin plate.

federal mogul 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 attached to the other end. Studs are used when the connected bodies have significant thickness, and double-ended bolts are employed to prevent loosening. In practical work, external loads such as vibration, changes, and high-temperature creep of materials can reduce friction, causing the normal pressure in the threaded pair to disappear momentarily, resulting in zero friction and loosening of the threaded connection. If this happens repeatedly, the threaded connection will become loose and fail. Therefore, anti-loosening measures must be taken. Studs are applied in various environments and are widely used in power, chemical, refining, valve, railway, bridge, steel structure, 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 steps in all structures. It continuously expands the application potential of structural design, offering high current capacity and shallow penetration depth. Therefore, it can be welded onto very thin sheets. The workpiece for stud welding must be welded from one side. It allows for full-position welding, and with the help of an extender, it can weld on restricted vertical partitions. Due to the short welding time and minimal post-weld deformation, no finishing is required. Since the welded structure does not require drilling, there will be no leakage. The joint can achieve very high strength, meaning that the joint strength of stud welding exceeds the strength of the stud itself. How to install double-ended studs: Good economic efficiency compared to other welding methods lies in the welding power. For mass-produced parts, standard studs are low-cost, and stud welding has a higher quality reproducibility rate and lower scrap rate.

federal mogul 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 profile 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 cap, use a torque wrench. Tighten according to specified standards, ensuring the torque is neither too high nor too low. Additionally, choose matching bolts and studs from the same manufacturer. 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.
