Your 5/64" (five sixty-fourths of an inch) torsion spring's measurements and dimensions have a lo to do with your standard torsion spring's force. For this reason, it is very important that the torsion spring's measurements are precise. Changing the wire diameter by even 0.001" can make a great difference on how strong your spring will be and how many degrees of travel you will be able to get out if it; especially with a spring as small as a 5/64" inner diameter torsion spring.

 

 

The 5/64" (five sixty fourths of an inch) inner diameter standard torsion springs provided here offer customers a wide variation of rate, load, and travel capacities. Every spring has its own amount of force due to the different physical dimensions; like wire diameter or total coils. The force chart to the right will explain what adjustments will make your spring stronger (more force) or weaker (less force).

 

For more force, you must either decrease your torsion spring's outer diameter, increase the wire diameter, take some coils out, or reduce the degrees of your torsion spring's free position by only taking a fraction of a coil out so you obtain more force through more travel. For less force, you must increase the outer diameter, decrease the wire diameter, add coils, or increase the degrees of your torsion spring's free position by only adding a fraction of a coil so you obtain less force through less travel.

 

These stock 5/64" (five sixty-fourths of an inch) inner diameter torsion springs are made out of either 302 stainless steel (ASTM A 313) or music wire (ASTM A 228).
