Snap-on QD2IN50A Torque Wrench Body, Adjustable Dual Scale, 10-50 N·m, J Shank for Interchangeable Heads

Description

A standard torque wrench ends in a fixed square drive. A body, by contrast, ends in an open receiver and waits for a head. The Snap-on QD2IN50A torque wrench body works this way. It is an adjustable click body with a 10-50 N·m range, and it accepts J-shank heads for socket, open-end, box-end and flare nut work.

What is a torque wrench body?

Think of the body as the measuring half of the tool. It holds the spring, the click mechanism and the scale. The head is the working half, so it decides what touches the fastener. On the QD2IN50A, push buttons release the head, and the next one slides in. As a result, one body can serve many joint types on the same bench.

Snap-on QD2IN50A torque wrench body specifications

Snap-on lists the ft-lb scale over a narrower band than the N·m scale, so check which unit your drawing uses before you set it. Lost in HCM’s listing names the QD2IN50A an adjustable dual-scale body with ±4% accuracy.

Choosing heads for the QD2IN50A

First, match the head to the shank letter. This body uses the J shank, which measures 0.425 in across. Next, match the head style to the joint:

• Square drive ratchet heads take sockets and crowfoot wrenches.
• Open-end heads reach nuts on a tube or cable with no free end.
• Box-end heads grip every corner, so they suit tight bolts.
• Flare nut heads hold brake, fuel and hydraulic line fittings.

Snap-on builds its matched heads so the pin-to-fastener spacing stays constant. For standard J heads that spacing is 2.50 in, so you do not need a correction. However, some heads sit further out, such as the SL ratchet heads. In that case, follow Snap-on’s head-length instructions before you trust the reading.

Where a 10-50 N·m QD2IN50A fits

Typical light joints include:

• Sensor brackets and connector housings in automotive sub-assembly.
• Cover and flange bolts on small pumps, so seals compress evenly.
• Terminal hardware inside control cabinets.
• Air and hydraulic tube fittings on packaging machines.

Adjustable or preset?

This is an adjustable body, so you turn the handle to any value on the scale. A preset body, on the other hand, stays dedicated to one value that a tool crib sets in advance. Choose the Snap-on QD2IN50A torque wrench body when targets change from job to job. A preset body suits a line that tightens the same joint all day.

QD2IN50A questions

Does the QD2IN50A come with heads?

The listing does not say. Snap-on sells heads under their own part numbers, so ask Lost in HCM to quote the ones you need.

Can it read in ft-lb?

Yes. It carries a second scale, which Snap-on lists from 9.2 to 35.0 ft-lb.

Will a Y-shank head fit?

The QD2IN50A uses the J shank, while Y heads have a larger 0.560 in shank. Order J heads for this body.
