Sensewee helps you select the right model—screw torque reference table

According to the material of the screw, they can be roughly classified as:
1. Standard T Series (Material: SS.SC): For general fastening applications, this series should be used whenever possible.
2. 0.5T Series (CR, CB, AB): Screws, internal threads, and fasteners made of die-cast products such as copper, aluminum, and plastic; plastic parts for electronic products.
3. The 1.8T series (SGr, SNC, SCM) features high-strength threaded connections made from special steel, particularly when bolts are subjected to additional dynamic loads (e.g., in vehicles and engines).
4. 2.4T Series (SGr, SNC, SCM, SNCM): Features high-strength threaded connections made from special steel, particularly suitable for construction applications where bolts are subjected only to static loads (frictional engagement).
 
Below is a table showing the nominal diameters and corresponding tightening torque values (in kgf·cm or mN·m) for the T series:
