Stainless Steel Screw Locking Inserts For Enhance The Thread
Strength
Information
What is the difference between ordinary wire thread inserts and
locking wire thread inserts?
A. The common type steel wire thread insert symbol "FR" is composed
of multiple spiral coils. By selecting a reasonable installation
length, an elastic connection is formed between the screw and the
thread inside the base, eliminating thread manufacturing errors and
improving the connection strength. Compared with the sleeve, the
additional volume and weight are reduced.
B. locking wire thread insert type, symbol "SL", non-deformed edge
of the locking ring is formed, functions as a fastening screw
assembly locking action of one or more turns by a polygon, having
all the characteristics of the ordinary type and the collar.
Feature
Screw Lock Thread Inserts besides have corresponding function
normal Thread Inserts, also played the lock screw tight in the
threaded hole, under vibration and impact, can make the screw does
not fall off string, locking device process performance is good,
than Free Running Thread Inserts has repeatedly disassembling and
not reduce the screw torque, but also has the high usability. Its
principle is in the middle of the thread, by one or more polygonal
non-deformation ring to form a locking edge, the assembly screw to
tighten the role of anti-loose.
1. The stainless steel thread has high strength.
2. The hardness of the screw surface can reach HRC43~50.
3. The surface accuracy can reach 2~4 μm.
4. Reduce the friction between the threaded surfaces. To
5. Increase the bearing capacity of the screws. To
6. Reduce the torque that the screw bears.
7. Make the load distribution on the entire rotating surface even.
8. Increase the load-carrying capacity of fasteners.
