How Should I Use a Torque Wrench?

Use a torque wrench to protect fasteners from damage and keep components properly secured. Here's how to use your torque wrench accurately:

• Start bolts/nuts by hand to prevent cross-threading.
• Look up the correct torque specs in your service manual.
• Set the torque value on your wrench according to the manufacturer's instructions.
• Position the wrench square and straight on the fastener.
• Apply steady pressure until you feel/hear the click or break.
• Stop immediately when the wrench signals; do not go past this point.
• Always store your wrench at its lowest torque setting.
• Get your torque wrench serviced annually to avoid loss of calibrations.
• Never use your torque wrench to break loose tight fasteners (use breaker bars instead).
• Clean the drive and socket interface before each use.
• Keep the mechanism free of dirt and debris.

What Is the “20 Rule” for Torque Wrenches?

The “20 Rule” states that torque wrenches must work between 20% to 100% of their maximum torque rating for optimal accuracy. For example, a 250 ft-lb torque wrench will provide accurate readings from 50 ft-lb up to its maximum of 250 ft-lb.

If you use a torque wrench below 20% of its max rating, it can create inaccurate measurements and cause potential fastener damage. For jobs that need lower torque values, a torque wrench with a lower maximum rating will meet your accuracy requirements.

To put this in practical terms:

• 250 ft-lb wrench = 50–250 ft-lb jobs
• 100 ft-lb wrench = 20–100 ft-lb jobs
• 50 ft-lb wrench = 10–50 ft-lb jobs

This rule exists because torque wrenches show the most accuracy in the middle to upper ranges of their scales. When you select a torque wrench, pick one with a maximum rating about 5 times higher than your most common torque requirements.

What Are the Different Torque Wrench Types?

There are several types of torque wrenches, each designed for specific applications:

• Click torque wrench creates an audible 'click' at the preset torque. 
• Beam torque wrench shows torque with a pointer across a scale. It is simple and accurate but takes practice to read.
• Dial torque wrench displays torque on a gauge face. It is easy to read but costs more.
• Electronic torque wrench shows numerical readings on an LCD screen. It offers data storage and programming but at the highest price point.
• Hydraulic torque wrench generates high torque through fluid pressure. Used in industrial work, requires a power source.
• Pneumatic Torque Wrench uses compressed air with adjustable settings. Low vibration for accurate results.
• Micrometer torque wrench controls torque by turning the handle. The micrometer wrenches have a ratchet function and auto-reset.
• Interchangeable head torque wrench accepts multiple wrench heads to reduce tool count.

Is a Digital or a Click Torque Wrench Better?

Digital torque wrenches and click-type torque wrenches each serve mechanics differently. Digital wrenches display exact numerical readouts, offer preset alerts, and store common torque values. They also export data for documentation; a useful feature for professional shops. But they require batteries and can fail in harsh conditions.

Click-type torque wrenches operate through simple mechanical systems that produce an audible click at the set torque value. They cost less than digital models and stand up better to tough shop conditions. With no electronics to malfunction, many mechanics trust their reliability for daily use.

Both types give accurate measurements when properly calibrated. Digital torque wrenches excel for precision work that needs exact numerical readings and data tracking. Click-type wrenches are great for regular shop use where mechanical reliability and durability matter most.

Does Olsa Offer Electric Torque Wrenches?

Olsa Tools does not offer electric torque wrenches. We manufacture two mechanical options: a click-type torque wrench and a split beam torque wrench. Both provide precise torque measurements through factory-calibrated mechanical systems that never need batteries.

Can I Use Socket Adaptors With Torque Wrenches?

Yes, socket adapters can be used with torque wrenches when you maintain proper alignment to avoid inaccurate readings. The adapter must fit tightly and stay within the wrench's torque rating. A straight, secure connection prevents measurement distortion. Olsa Tools socket adapters and ratcheting torque wrenches deliver accurate results together.

What Kinds of Sockets Are Compatible with Torque Wrenches?

Torque wrenches accept both standard chrome sockets and impact sockets. The square drive size matches regular ratchets (1/4, 3/8, or 1/2-inch), so any socket with the corresponding drive size will fit.

Standard chrome sockets work best for most torque applications on lug nuts, cylinder heads, and engine components. Impact sockets fit torque wrenches too, but their extra weight serves no purpose since torque wrenches do not produce impact force. The thicker walls of impact sockets can also restrict access in tight spots during torque applications.

What’s the Difference Between a Torque Wrench and a Standard Ratchet?

Torque wrenches and ratchets both use sockets to tighten fasteners, but torque wrenches measure and control the exact tightening force. Torque wrenches produce a click or signal at your preset torque value to prevent over-tightening. Standard ratchets don’t measure tightness.

Standard ratchets work well for basic repairs and maintenance. Automotive applications, equipment assembly, and large electronics require torque wrenches to avoid component damage from improper tightening force. The precise control of a torque wrench protects your valuable parts and equipment.

Does the 15-Degree Flex Head Reach All Common Fastener Angles?

The 15-degree flexible head on Olsa's torque wrenches accesses the most common fastener spots in auto work. The head has a 30-degree total range (15 degrees each way), reaching bolts and nuts that fixed-head models can't get to.

The 72-tooth ratchet adds to this flexibility for work in tight engine areas. The wrench maintains its ±3% clockwise and ±5% counter-clockwise accuracy even at angles.

For extreme angles past 15 degrees, you will need extensions or universal adapters. Always aim to position the wrench as straight as possible on the fastener.

How Small Is the Minimum Arc Swing With the 72-Tooth Mechanism?

A 72-tooth mechanism divides 360 degrees into 72 sections to create a 5-degree minimum arc swing. This means the wrench only needs 5 degrees of movement to catch the next tooth—about the width of your thumb at the end of the wrench.

For comparison, a 36-tooth ratchet needs 10 degrees to move, doubling the space needed. The 5-degree swing lets you work in tight spots where larger movements aren't possible.

What Other Torque Products Does Olsa Offer?

Olsa Tools offers torque screwdrivers with hex heads. These torque tools deliver precision torquing for smaller fasteners while standing up to heavy-duty tasks in automotive, industrial, and mechanical applications.

What Makes a Torque Wrench a Must-Have for Professionals?

A powerful torque wrench combines precision, durability, and usability. Serious auto work demands tools that meet the requirements of professionals. Features such as a square-drive ratchet head, 72-tooth mechanism, and 15-degree swing arc provide a seamless, accurate operation. And durable Cr-V steel offers long-lasting corrosion resistance so your professional tools stand up to the test of time. 

Does Olsa Offer Adjustable Wrenches?

We carry a 10-inch adjustable plier wrench for general-purpose work. You can also try our ratcheting wrench sets for a range of commonly needed sizes.
