Ensure Stability and Safety with Lock Bolts Collars for Satellites and Rockets

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.
