1) Structures of Lock Bolt & Collar
A bolt is usually a cylindrical metal rod with an external thread,
which may have a head at one end and is used to apply torque to
achieve tightening. A collar, on the other hand, is a metal ring
with an internal thread that engages two or more parts tightly
together
by engaging with the external thread of the bolt.
2) Surface treatment technology
a) Galvanizing: economical anti-rust, divided into electroplating
and hot plating
b) Dacromet: Excellent corrosion resistance, no hydrogen
embrittlement
c) Blackening treatment: beautiful, rust prevention ability is
average
d) Nickel plating: highly decorative, medium corrosion resistance
e) PTFE coating: anti-friction and chemically resistant
3) Applications of Lock Bolt & Collar
a) Industrial manufacturing: mechanical equipment, production line
equipment
b) Construction field: steel structure connection, curtain wall
installation, bridge construction
c) Automotive manufacturing: engine components, chassis and
suspension systems, body assembly
d) Aerospace: aircraft structures, satellites and rockets
e) Other areas: shipbuilding, agricultural machinery
Lock Bolt & Collar is the basis for mechanical stability as
standardized connectors. Its design needs to choose the appropriate
type,
material and specification according to the load size,
environmental conditions, installation space, etc., and pay
attention to preload control
and anti-loosening design during installation to ensure the
reliability and safety of the connection. From everyday items to
large-scale projects,
the "tiny role" of bolt nuts supports the proper functioning of
almost all mechanical systems.
