Gangtong Zheli is China manufacturer & supplier who mainly produces Galvanized Steel Zinc Plated Press Self Clinching Nut with many years of experience. Hope to build business relationship with you. In situations where there is a risk of nuts coming loose due to vibration or rotation, various locking mechanisms can be employed to ensure secure fastening. These mechanisms include lock washers, jam nuts, specialized adhesive thread-locking fluids like Loctite, safety pins (split pins), or lockwire used in conjunction with castellated nuts, nylon inserts (Nyloc nuts), or slightly oval-shaped threads.
The most common nut shape is hexagonal, primarily for the same reasons as hexagonal bolt heads. Hexagonal nuts have six sides, which provides a convenient range of angles for a tool to grip and access, making them suitable for use in tight spaces. Additionally, it only takes a 1/6th rotation to move to the next side of the hexagon, ensuring optimal grip. Polygons with more than six sides do not offer the same level of grip, while those with fewer sides take more time to complete a full rotation. Specialized nut shapes, such as wingnuts for finger adjustment or captive nuts like cage nuts for use in inaccessible areas, exist to meet specific requirements. Nuts come in a wide variety, ranging from household hardware versions to specialized designs engineered to meet industry-specific technical standards. Fasteners used in automotive, engineering, and industrial applications often require precise torque settings, which are achieved using a torque wrench. Nuts are graded with strength ratings that match their corresponding bolts. For example, an ISO property class 10 nut is capable of supporting the proof strength load of an ISO property class 10.9 bolt without stripping. Similarly, an SAE class 5 nut can withstand the proof load of an SAE class 5 bolt, and so on.
A nut is a type of fastener with a threaded hole. Nuts are almost always used in conjunction with a mating bolt to fasten two or more parts together. The two partners are kept together by a combination of their threads' friction, a slight stretching of the bolt, and compression of the parts to be held together.
