TSD-12-20
20mm expend torque adapter
This is a brand new concept of big torque adapter from 6~18Nm which is never been done before. We believe it could be used for auto, motocycle and other heavy torque control application. Our torque adapter works with all kinds of handle and tools. Please contact with us if you have any ideas.
Features
- The torque adapter is functional by the radial direction friction; it is different from
- the marketed product nowadays. When an object slips or is going slip with another object, on the two contact faces
- will create a relative action. This relative action is called the static friction,
- it creates the abrasion after use a certain time. The preset torque of adapter may
- get low due to this abrasion.
Specification
- Material: Carbon Steel
- Hardness: HRC 43° ~ 48°
- Surface Treatment: Electroless Nickel
- Unit conversion: 1 Nm = 10.20kgf-cm
