- Spring constant (N/mm), adhesion length, and spring constant are reference values.
- Durability and chemical resistance vary depending on usage conditions, so be sure to test under usage conditions.
- Constant of sprong (N/mm).
- Closed length and spring rate are reference values.
- Since durability and chemical resistance change based on usage conditions, please test under actual usage conditions beforehand.

Torsional rupture torque
Tensile rupture force
- We use raw materials that are RoHS2 compliant.
- Black spots (sludge) may appear on the exterior.
- The remaining gate at the screw tip is less than 5% of the length (L).
- Please use in combination with a nut made of the same material as the thread pitch may shift during molding.
- If a nut is not used, the fit with the female thread should be 20 mm or less.
Features
- The values in the table are reference values and are not guaranteed values.
- Please use a torque driver and torque wrench for tightening. The recommended tightening torque is 50% of the breaking torque value under use.
- Heat resistance and chemical resistance vary depending on usage conditions, so be sure to test under usage conditions beforehand.
- There may be slight discoloration depending on the lot and various conditions.
- Inventory sizes, shapes, and manufacturers of materials used are subject to change without notice.
