Black Oxide Steel Ball Point Set Screw M4 Hex Socket Harden
Fastener Grade 10.9
Ball point set screw is called plunger screw as well , it is one of
the best fasteners for mechanical trasimit in industry .set screw
has a hexagonal socket for driven by a hex key or hex wrench , and
a steel round ball is put into end of the set screws when a spring
was insert hole of set screw . this deisgn makes round ball can be
adjusted distance according to pressure of the object .
Ball point set screws are made of alloy steel with hardening grade
10.9 , they are capable of heavy duty and hard working surroundings
.
Set screw with ball point that easily solve problems of adjusting
pressure and location of working pieces during assembly .the
materials of round ball can be carbon steel , stainless steel or
plastic etc for different applications .
Finish
Set screw are coated in black oxide , besides , zinc , nickel ,
dacromet and brass etc finishes are available as well .
