Preset Micrometer Torque Wrench

The Jonard TWAF-71640 is a factory-set torque wrench designed for technicians who need a single, repeatable tightening value. It operates at a fixed 40 in-lb setting with a 7/16 in drive, removing the need for on-site adjustment during repetitive assembly tasks.

Clockwise And Counterclockwise Operation

The wrench accepts force in both rotation directions, allowing use on standard and reverse-thread fasteners without changing tools. A full-head design distributes load across the fastener face, while the tether-capable handle supports safety-lanyard attachment for elevated work environments.

Factory Calibration And Compliance

The tool arrives calibrated to the stated 40 in-lb value, so it can enter service immediately without a preliminary verification step. A California Proposition 65 notice applies, informing users that the product contains chemicals identified by the state as causing cancer and reproductive harm.

Questions about this item

How do I install the Jonard TWAF-71640 torque wrench on a 7/16 inch fastener without over-tightening?

Set the micrometer to 40 in-lb, engage the 7/16 inch drive on the fastener, and apply force clockwise or counterclockwise until the wrench signals the preset torque is reached.

What maintenance will the Jonard TWAF-71640 torque wrench need over time?

Periodically verify calibration at the 40 in-lb setting, clean the 7/16 inch drive and ratchet mechanism, and store the wrench at its lowest setting to maintain spring accuracy.

What is the first limit reached when using the Jonard TWAF-71640 torque wrench continuously?

The fixed 40 in-lb torque ceiling is the primary limit; sustained use at this maximum value will trigger the preset release mechanism on every cycle.
