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
