M3 - M42 Size Grade 8.8 Fully Threaded Hex Bolts For Architecture
Six angle bolt: a fastener consisting of two parts, the head and the screw (the cylinder with external thread). It needs to cooperate with the nut to fasten and connect two parts with through holes.
This form of connection is called a bolt connection. If the nut is swirled down from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
They are used usually in chemical, food, medical, maintenance, machinery and agriculture industries where corrosion resistance is required
There is a special high strength bolt on the steel structure. The head will be bigger and the size changes.
Advantage:
Threaded rod provides a means of hanging or suspending strut, conduit systems, piping, etc. The Threaded rods are used to building fasteners with standard thread.
It must be carefully if substituting a headed bolt for threaded bar and nuts because there will usually be a reduction in strength.
