axiom 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 to securely connect the two parts into a single unit. This type of connection is called a stud connection and is a detachable connection, primarily used when one of the connected parts has significant thickness, requires a compact structure, or involves frequent disassembly where bolted connections are unsuitable. The press-fit nut stud has a hexagonal shape at one end and a cylindrical shape at the other, with an undercut between the hexagonal section and the cylindrical section. The interior features an internal thread. A press forces the hexagonal head into a pre-drilled hole in the thin plate, causing plastic deformation around the hole. The deformed material is pressed into the undercut of the press-fit nut stud, securing it to the thin plate and forming a reliably fixed internal thread on the thin plate.

axiom fastener applications

A stud refers to a cylindrical fastener with threads on both ends. It is used in large equipment as the main body where accessories such as sight glasses, mechanical seal seats, and gearbox frames need to be installed. In these cases, a stud is used: one end is screwed into the main body, and after the accessory is installed, a nut is fitted on the other end. Studs are used when the connected bodies are very thick. Double-ended studs serve anti-loosening purposes. 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 thread pair disappears, friction becomes zero, and the threaded connection loosens. Repeated action causes the threaded connection to relax and fail. Therefore, anti-loosening measures are required. Studs are applied in different operating environments and are widely used in electric power, chemical industry, oil refining, valves, railways, bridges, steel structures, automotive and motorcycle parts, machinery, boiler steel structures, tower cranes, large-span steel structures, and large buildings.

axiom fastener installation

Studs save time and cost. Structures do not require drilling, punching, threading, riveting, screwing, and finishing steps, continuously expanding the application potential of structural design. They support high current and smaller melt depth, allowing welding onto very thin plates. Stud welding workpieces must be welded from one side. All-position welding is possible; with extenders, welding can be performed on restricted vertical partitions. Due to short-duration welding and minimal post-weld deformation, no finishing is required. Since drilled holes are not needed for the welded structure, leakage is avoided. Joints can achieve high strength, meaning the joint strength of stud welding exceeds the strength of the stud itself. How to install double-ended studs with good economic efficiency. Compared to other welding methods, the advantage lies in welding power. For mass-produced workpieces, standard studs are low-cost, and stud welding offers high quality reproducibility and a lower scrap rate.

axiom fastener maintenance

During each maintenance, inspect newly replaced studs and other newly replaced components. Focus the inspection on the head and guide portion of the stud. Strictly check each part of the thread for cracks or indentations, and examine the tooth profile of the stud for any changes. Check for abnormal pitch. If abnormalities occur, do not use the stud. Use a torque wrench when installing the connecting rod cap. Tighten according to specified standards; torque must not be excessive or insufficient. Also, ensure selection of bolts and studs from matching manufacturers. Routine maintenance of studs is necessary. Problems may arise from long-term mechanical friction. When issues occur, remove the engine oil pan and carefully inspect the condition of the engine bearings. Check if the clearance between bearings is excessive. If the clearance is too large, replace them promptly.
