Stainless Steel Hexagon Head Bolts DIN931 / A2-70 Hex Head Screws
DIN931 hexagonal bolts, also known as external hexagonal bolts, are fasteners consisting of two parts: a hexagonal head and a screw with external threads, which are generally used in conjunction with nuts and are commonly used to fasten connections between two parts with through holes.
DIN931 hexagonal bolts are half thread. partly threaded and partly bare rod. The thread include coarse and fine teeth.
DIN931 hexagon bolts with coarse teeth are often used in conjunction with nuts, using a threaded connection to connect the two parts into a whole, which is a removable connection. The fine tooth is the same as the coarse tooth, but the fine tooth hexagonal bolt has good self-locking performance, and is mostly used for parts subject to large impact vibration or alternating load, and can also be used for the adjustment of fine adjustment mechanism.
Hexagon bolts in use should pay attention to anti-loosening, otherwise it will affect the normal work and cause accidents. Anti-loosening methods are: friction anti-loosening, mechanical anti-loosening or other anti-loosening measures.
Hexagonal bolt connection, simple assembly, easy disassembly, high efficiency, and wide application, mainly used in various mechanical equipment, electronic products, communication equipment, furniture equipment, construction industry and other industries of production, installation, maintenance, etc..
