Snap-on ATECH3F300GB Torque Wrench, Green TechAngle 1/2″ Flex-Head, 15-300 ft-lb

Description

Bus and truck assembly plants in Quang Nam and Hai Phong build chassis that carry heavy loads for years. Their quality teams check suspension, steering and body mounts against a spec sheet. The Snap-on ATECH3F300GB torque wrench supports those checks with a 1/2-inch drive, a sealed flex head and a 15 to 300 ft-lb range. Snap-on’s catalog lists it as the green version of the ATECH3FR300B.

Key data at a glance

• Range: 15-300 ft-lb, or 20.3-406.7 N·m.
• Ratchet: 80 teeth with a 4.5° gear action.
• Length: 30 in, so it gives good leverage at the top of the range.
• Weight: 3.95 lb (1.79 kg) without batteries.
• Power: three AA alkaline cells.

Line and audit roles for the Snap-on ATECH3F300GB torque wrench

On the line, operators often run click or pulse tools at one value. Then a quality inspector rechecks a sample of joints with an electronic wrench. This tool fits that audit role well, because it shows a number rather than just a click. For example, an inspector can verify spring U-bolt nuts, steering box bolts and cab mounts in one round.

Torque plus angle on chassis joints

Some chassis specs add a turn after the torque step. The TechAngle line handles that with a torque-then-angle mode, so the wrench stays on the bolt. Angle accuracy is plus or minus 1% of reading, plus or minus 1 degree, per Snap-on.

Keeping it audit-ready

An audit tool needs a clean record of its own. So label its calibration due date and check it on a fixed cycle with an outside lab. Also keep it in its case, apart from production tools. Finally, swap batteries at the first low-battery warning.

Which units can the ATECH3F300GB display?

Snap-on lists ft-lb, in-lb, N·m, dN·m, kg-cm and angle for TechAngle models.
