- Person who would like to know the exact “tightening torque” of tapping screws.
- Person who would like to know the optimum hole diameter for fastening tapping screws.
- Person who wants to find the best one from “many kinds of tapping screws”.

Tightening and breaking tests can solve this problem!
What you need for the torque test
◆screws
◆workpieces(mating material, intermounting material, fixing jig, etc.)

N=10 is recommended per of conclusion.
(To check for variations,averages,and abnormal data)
For comparison tests,please also prepare screws and workpieces to be compared.

Other torque tests that can be performed
- Return torque test
Return torque after tightening can be measured.
Loosening characteristics of screws can be analyzed.
- Repeat test
The number of repetition limits of tapping screws can be verified.
