#2 Working Drawing of a torsion spring

 

#3 Different Shapes of Helical Torsion Springs
There are generally two common types of torsion springs: single and double coil torsion springs. Double torsion springs are two single torsion springs connected. They work together to double the torque that a single spring would produce.

#4 Available Coating Method
Due to the government's environment policy, all the coating materials are prior to RoHS standards. Please take RoHS standard coating as possible as you can. Below is a table for reference, you can simply learn the cost of each coating method.

Coating Method	Cost	Does it Meet the RoHS requirement?	Remark
Unplated	None	Yes
Anti Rust Oil	Lowest	Yes
Black Oxide/Oxide	Lower	Yes
