torque screwdrivers

Digital models advertise high accuracy (up to ±2%) and typically provide real-time and peak measurement modes, plus multiple preset slots for saving torque values.

Common indicators include an audible click and an automatic slip/auto-slip mechanism that engages at the preset torque. Digital models also use a backlit display to show current readings.

Kits commonly include flathead, Phillips, hex, and Torx bits plus accessories such as an extension/extension bar, a small ratchet head or T‑handle, a tool box/carrying case, and in some digital kits, AAA batteries.

Heads/blades are commonly made from alloy steel for strength and wear resistance. Bodies often use aluminum alloy for lighter weight, while digital handles frequently use ABS and TPE plastics.

Protection typically comes from an audible over‑torque click and an automatic slip/auto‑slip mechanism that engages near the preset torque to help prevent over‑tightening or damage.
