3/8 in drive micrometer torque wrench

The Jonard TWSW-40 is a new 3/8 inch drive micrometer torque wrench built from alloy steel with a black oxide finish. It delivers a maximum torque of 40 in lb with accuracy of +/-4% clockwise and +/-6% counter-clockwise between 20 and 100% of full scale. A swivel head allows access to confined fasteners in automotive and electronics work.

Technicians needing bidirectional low-torque

This wrench suits technicians who require precise, repeatable torque in both tightening and loosening directions on small fasteners. The 40 in lb upper limit means it is not for buyers who need higher torque values for larger bolts or structural fixings. The micrometer scale requires manual reading, so users wanting a digital display or preset click targets should consider other tool types.

40 in lb maximum torque with 3/8 in square drive

The decisive specification is the 40 in lb maximum torque capacity combined with a 3/8 inch square drive. This defines the fastener size range and tightening force the tool can accurately deliver. Confirm that your application falls within the 20 to 100% working range and that the drive matches your socket set before purchasing.

Questions about this item

What drive size must my sockets have to fit this 3/8 in torque wrench?

Your sockets need a 3/8 inch square drive to engage the wrench's anvil correctly.

Will the +/-4% clockwise accuracy still apply when I use the wrench at the low end of its 20 to 100% scale?

Yes, the stated +/-4% CW and +/-6% CCW accuracy is maintained across the full 20 to 100% of full scale range.

How can I verify the wrench is clicking at the correct 40 in-lb setting after I set it?

Mount the wrench on a calibrated torque tester and confirm the click occurs at 40 in-lb within the +/-4% tolerance.
