Snap-on TECH1J240 Torque Wrench, Interchangeable-Head J-Shank Techwrench, to 20 ft-lb (240 in-lb)

Description

Some fasteners hide behind tubes, brackets and connectors where a ratchet head cannot reach. The Snap-on TECH1J240 torque wrench answers that problem with interchangeable heads. It is an electronic Techwrench with a J-size shank, 0.425 inch across. You fit the head the job needs and read torque on the display. Its range tops out at 240 in-lb, or 20 ft-lb.

How an interchangeable-head wrench works

The TECH1J240 handle holds the electronics, while the head slides onto the shank. So one wrench covers many fastener types. However, a head that adds length changes the lever. Then the torque at the fastener can differ from the reading. Check Snap-on’s guidance for each head before you set a target.

Fixed head or interchangeable head?

Snap-on files the TECH1R240 under its 2% accuracy group, while the TECH1J240 sits in the 4% group. So, for the best accuracy on open joints, pick the fixed-head model. On the other hand, the TECH1J240 wins where access matters more, for example on tube nuts and flare fittings. Also note that neither model has an angle mode. That feature belongs to Snap-on’s TechAngle range.

Where the Snap-on TECH1J240 torque wrench helps

• Brake and fuel line flare nuts.
• Small hydraulic and pneumatic fittings.
• Sensor connections inside tight control panels.
• Cooling lines on test rigs and electronics racks.

Looking after heads and handle

Wipe each head and the J shank before you fit them, because grit stops a clean seat. Keep the heads in labeled trays, so nobody grabs a head from another set. Then store the Snap-on TECH1J240 torque wrench handle in its PBTECH2 case. Finally, book recalibration on a fixed cycle, as Snap-on advises.

J-shank FAQ

Can I fit a J head on a larger Techwrench?
