Do I Need to Calibrate Pneumatic Torque Wrenches? Ohmstede’s Experience with RAD

A RAD Torque wrench is known for its durability—but regular servicing and calibration are what ensure long-term accuracy and performance. With proper maintenance, a RAD tool can last for decades.

Ohmstede’s Experience with RAD Torque Tools

Ohmstede Limited, a leading provider of field maintenance for shell and tube heat exchangers, relies on consistent torque performance in demanding environments.

In 2005, Ohmstede adopted RAD Torque tools through Torque Tools Inc.

“Before we introduced RAD Torque tools, they were using hydraulic and manual torque wrenches,” says Steve Force.
“They’ve since invested in RAD tools for their speed, ease of use, and ability to maintain accuracy compared to slower hydraulic systems.”

Do You Need to Calibrate Pneumatic Torque Wrenches?

Yes—calibration is essential.

Even the most durable pneumatic torque wrench will experience minor changes in output over time due to:

• Continuous use
• Wear on internal components
• Environmental conditions

Regular calibration ensures:

• Accurate torque output
• Compliance with industrial standards
• Reduced risk of under- or over-tightening

RAD Torque Systems recommends annual calibration and servicing to maintain optimal performance.

Real-World Proof: A 16-Year-Old RAD Torque Tool

Christian Thomas shared a photo of his RAD Pneumatic 350 SL—used daily on heat exchanger applications.

• Tool age: 16 years
• Usage: Daily, shared across crews
• Condition: Visibly worn, still fully functional

“We use these tools every day. If I’m not using it, someone else is,” says Thomas.

Despite heavy use, performance remains consistent.

Why Servicing and Calibration Matter

“The tool will keep working forever as long as we service and calibrate it every year,” says Bobby Branam.

This longevity comes down to engineering. RAD Torque gearboxes feature bearings in each stage assembly—reducing internal wear and preventing failure points commonly seen in competing tools.

Built for Long-Term Industrial Use

The RAD Pneumatic 350 SL, part of the Single Speed Series, is designed for:

• High torque applications
• Daily industrial use
• Long-term reliability with minimal downtime

With proper calibration, it remains a dependable industrial torque solution even after years of service.
