Stainless Steel Fasteners Screw Thread Inserts Dimensions Assembly
Inch Series
Introduce
Designed and manufactured by thread insert to provide specific and
unique benefits to high-temperature, high-performance spark plug
applications.
thread insert spark plug screw thread inserts are manufactured from
18-8 round stainless steel wire formed into a 60° diamond-shaped
wire. This cold-worked wire, which has a tensile strength of
200,000 PSI, is wound into a helical coil with a driving tang and
notch to remove the tang after the insert is screwed into the
thread insert tapped hole.
Advantage
1. Increase the bearing surface. It is used for parts that require
a strong connection force and cannot increase the diameter of the
screw hole.
2. Anti-loosening. It is especially used in occasions where
products such as spacecraft require a high insurance factor.
3. Easy to maintain. Install the damaged screw hole into the steel
wire screw sleeve and continue to use it after repairing to avoid
the possibility of damage to the work piece.
