Snap-on PTM2950 Pneumatic Torque Wrench, 1-1/2″ Drive, 590-2,950 ft-lb (800-4,000 N·m)

Description

How long does your team spend on one flange with a manual multiplier and a click wrench? On a shutdown with hundreds of joints, those minutes add up fast. The Snap-on PTM2950 pneumatic torque wrench turns that work into a steady, repeatable air-powered run. Snap-on rates it for 590-2,950 ft-lb, or 800-4,000 N·m, so it covers a broad band of heavy maintenance bolting.

Drive size: check before you order

The Snap-on Industrial catalog lists the PTM2950 with a 1-1/2 in square drive. It also shows a PTM2950SA version with a 1 in drive and the same torque range. So match the order to the sockets your crew already owns. For example, a site with a full 1 in impact socket set may prefer the SA version.

Manual multiplier or Snap-on PTM2950 pneumatic torque wrench?

A manual gearbox costs less and needs no air. However, the operator must pull the input wrench through many turns on every bolt. The PTM2950 uses twin motors, so it spins the nut down quickly and then builds the final load without impacts. As a result, a two-person crew can finish a bolt pattern with less fatigue and more even results. Snap-on states ±5% accuracy for the PTM series, which suits most structural and flange work.

Plants that fit the 800-4,000 N·m band

For example, the Snap-on PTM2950 pneumatic torque wrench suits these sites:

• Power stations: turbine casing, generator and boiler feed pump bolts.
• Steel and cement plants: gearbox mounts, roller press and mill bolting.
• Oil, gas and chemical sites: large pipe flanges and heat exchanger heads.
• Heavy equipment builders: frame, axle and track bolts on assembly lines.

Air supply checklist

• Fit the Snap-on PTMFRL filter/regulator unit, because the catalog lists it as required for the PTM2950 and other PTM tools.
• Keep the compressor output steady, since pressure sets the final torque.
• Use the torque vs. pressure chart that Snap-on supplies with each PTM tool.
• Run one trial joint, then lock the regulator for the rest of the pattern.

Operator safety

The secondary trigger keeps hands clear of pinch points during the run. Also brace the cranked reaction fixture on a strong, square surface. The gearbox rotates independently from the handle, so the reaction stays in the fixture.

Daily checks for the PTM2950

Start each shift by draining the air filter and checking the lubricator level. Then inspect the drive square and reaction fixture for cracks. In addition, store the tool in its case, away from dust and grit. Plan a regular torque output check, especially after a drop or a hard season.

PTM2950 questions from shutdown planners

Can I get the PTM2950 with a 1 in drive?

Snap-on lists a PTM2950SA version with a 1 in drive. Ask Lost in HCM which version they can supply.

Does it work as an impact wrench?

No. It is a non-impacting tool, so it gives a smooth final load and low vibration.

What controls the output torque?

Air pressure does. Set it on the regulator, using the torque vs. pressure chart that comes with the tool.
