  • Product colorTransparent
  • Prevents wheel and stud damage by stopping at 80 ft‑lb torque
  • No recalibration needed thanks to maintenance‑free internal mechanism
  • Chrome molybdenum steel construction delivers professional‑grade durability and long service life
  • Powder coat finish resists chipping, scratching and fading for lasting appearance
  • Colour‑coded blue with stamped markings allows quick size identification on the job

Torque-Limiting Extension for Wheel Service

This 1/2 in drive extension stops turning once the preset torque value is reached, protecting wheels, studs and brake rotors from over-tightening. It is built for tire shops, automotive repair bays and fleet maintenance teams that need repeatable accuracy on lug nuts.

Chrome Molybdenum Build with Powder Coat Finish

Professional grade chrome molybdenum steel provides maximum durability and long life under daily shop use. The powder coat finish resists chipping, scratching and fading, while colour coding and hard stamped markings allow quick identification in a busy tool drawer.

Replaces Standard Extensions When Torque Control

The maintenance-free, recalibration-free design removes the guesswork from manual tightening, making the jump worthwhile whenever consistent lug-nut torque is required for safety and warranty compliance. It is not suited for applications that demand adjustable torque values or non-automotive fastening tasks.
