Standardized Fasteners
Standardized fastening coupling with mechanical parts. Standardized fasteners mainly include bolts, studs, screws, set screws, nuts, washers and rivets, etc.
Bolt structure type many, the head is mostly hexagonal. Subject to shock, vibration or variable load of the bolt, in order to increase flexibility, its light rod part made of thin section or hollow. The seat end of the stud is screwed into the threaded hole of the coupling, the nut end with a nut similar to the bolt nut. The structure of the screw and the bolt is largely the same, but the head shape is varied to accommodate different assembly space, tightening degree and the appearance of the joint. Fastening screws have different head and end shapes to accommodate different tightening levels. Nuts also have a variety of types, with hexagonal applications widely.The main classification includes ordinary screws, machine screws, self-tapping screws and expansion screws.
Cap screw with head used to be limited to full tooth fasteners.
Hex cap screw and Hex bolt are, as the name implies, male fasteners with a hexagonal head and are designed to be turned with a wrench. According to ASME B18.2.1 standard, Hex cap screw has a smaller tolerance on head height and rod length than a typical large hex bolt, so ASME B18.2.1 Hex cap screw is suitable for installation where all hex bolts can be used, and also where large hex bolts are too large to be used.
Socket cap screw (also known as socket cap screw or) is a screw with a hexagonal bore in the head, which can be tightened or loosened by inserting a hexagonal ruler (hex key, Allen wrench or Allen key) into the bore. Other head types include the Bottom head cap screw, which provides an attractive surface, and the Countersunk head cap screw, which is suitable for tapered screw holes. The countersunk hole design allows the screw head to be used without the countersunk hole design allows the screw head to rotate without being exposed on the surface of the fixed object, so it is mostly used in places where the surface is small and traditional plate hand is not convenient to use.
