- "Turnbuckle, 1", Jaw-Jaw, Forged Steel, Diameter = 1.00", Take Up = 12.00" and Ult. Strength = 50,000 LBS
- The torque required to rotate the bossof a turnbuckle under tension can be calculated by the formula:
- T = 2 (kdW/12) ft-lb
- Where: k = Friction factor (0.16)
- d = Nominal thread diameter (inches)
- W = Applied tension load (lb)
- Example: 1-1/2" turnbuckle under 4,000 lb tension
- T = 2(0.16 x 1.00 x 4000 / 12) = 107 ft-lb"
