The BAHCO Short Story

In 1889 a salesman in Sweden named Bengt August Hjort joined with two inventors of handtools, F. E.
Lindstrom who had invented wire cutters so strong they could cut the hard wire used to make fish
hooks, and J. P. Johansson who had created the first adjustable pipe wrench. Mr. Hjort named the
enterprise after himself: B. A. Hjort Company, which was eventually shortened to BAHCO and is now
commonly written as Bahco...

What is a torque wrench?

A torque wrench is any device that applies a pre-determined amount of torque to a fastener.
• It may be mechanical or electronic in design.
• A torque wrench has some type of indicating device which lets the operator know when the correct torque has
been achieved: "click" or "impulse-break"; feel; sound; lights; gauge; or some combination of these.

Quick Fact: The Micrometer Click Type Wrench (Shown) is the most affordable and common torque
wrench used today.

Qualifying the need and cost savings of an in-house calibration system is relatively easy.

1) Perform a simple "Torque Audit" of your facility:

A) Identify how many torque wrenches are used in the facility.
B) What types of torque wrenches are used? Micrometer, dial, digital, torque screwdriver, etc.
C) What are the torque ranges of the tools, low to high?
D) Do you have a Quality Control lab, tool room, or maintenance department that would perform the torque calibration? If so, meet with the leader and staff of that department to decide what you need.

Safety & Performance. Applying accurate torque is critical to assembly applications, engines
and precision equipment.

- Creating a proper clamp load is the main objective when applying torque to a fastener.
Engine cylinder heads, pipe coupling, wheels, all need to be “clamped" uniformly to specific
torque values.

- There are three main factors that affect the correct application of torque: (1) Condition of
components, (2) Accuracy of torque instrument, (3) Properly applied torque values.

- Appling torque incorrectly can lead to stripped threads, premature loosening or broken
fasteners that can cause catastrophic failure. Leaking joints may cause engine or equipment

Torque Definitions

R.S.M.El. — American Society of Mechanical Engineers, known for setting codes and standards for mechanical
devices, including torque.

CW — Clockwise. Used in all accuracy statements & Certs. Some tools have different accuracy depending on direction of use.

CCW— Counter Clockwise

Calibration - Adjusting a torque tool or a torque transducer to bring it back within spec, which is performed on a
calibration system such as the CDI 2800-1 or 2000-1. Typical calibration accuracy is t 4% CW of indicated

Certifications — Also called a "Cert", this is a form which lists the results of the calibration test. Almost all CDI tools are supplied with a N.I.S.T. traceable cert. CDI also conforms to the ISO 6789, which is the standard set forth by the International Organization for standardization (ISO) for torque measurement...

Types of Torque Wrench


DESCRIPTION: Also referred to as a "click" wrench, these are the most popular type of mechanical torque wrench. An internal spring is tightened by turning the handle. The spring pushes against a block, and both are calibrated so the block pivots when the torque setting has been reached. This quick pivoting creates the "click" sound. When the force at the handle is released, the block resets to its original position and is ready for the next torque application.

OPERATION: Set the desired torque value by pulling down on the lock ring while turning the handle. Al- ways
approach torque setting from a lower setting. The tube displays the major torque values, and the lock ring has the
minor torque values. Apply force at the handle until the "click" is felt or heard, and then release force.

ADVANTAGES: Most common type of torque wrench. "Click"felt at the handle indicates torque value reached.
Rugged, durable legacy design.

DISADVANTAGES: After day's use, internal spring pressure must be released by unwinding the handle.

APPLICATION: Highly versatile: any general-purpose torque applications: auto engine, machine maintenance,
construction, oil field, compressor/generator, etc.

What is torque wrench calibration?

A torque “wrench” is really a precise torque instrument used to accurately apply a predetermined
amount of torque to a fastener. “Calibration” is a set of operations to check and adjust the measuring
performance of a torque wrench to establish accuracy standards.

Torque wrench calibration standards are set by The American Society of Mechanical Engineers (A.S.M.E)
and are the recognized standard in the U.S and internationally. This is the standard used to manufacture
and test all CDI torque wrenches.

Torque Testers Overview

Facilities that utilize torque wrenches may want to conduct daily or periodic testing to help ensure they
are functioning accurately every day. CDI Checkers and Testers come with a range of features and
accuracy levels, depending on the needs and budget of the customer.

Calibration Systems Overview

Facilities that utilize many torque wrenches recognize the benefits of performing in-house calibration of
their wrenches. In-house calibration saves time and money, and ensures the wrenches used meet
standards, or calibration requirements that may be unique to the customer. Typical company
departments that manage and perform calibration would be “metrology” (instrument measurement),
tool Room, Maintenance, Quality Control/Assurance, etc.

Calibration System vs Tester

Torque calibration systems are more accurate than testers, due to their sophisticated electronics combined with finely geared mechanical loaders, which apply consistently precise torque to the tool being calibrated (adjusted) and certified.

Torque testers are used too quickly to check the accuracy of a torque wrench, and should not be used for calibration.

“Testing” is normally performed between calibrations as periodic confirmation that the torque wrench is operating properly.

Torque testers are also effective to train torque wrench users on how to properly apply torque.

Why Calibrate?

Why Calibrate?

Whether mechanical or electronic, precision torque wrenches require calibration because the internal mechanisms can wear, fatigue, or become jolted out of accuracy by a drop or a misuse.

How does a Calibration System Work?

How does a Calibration System Work?

A torque wrench, set at a specific value, is placed in the calibrator with the handle held stationary.

The square drive is placed into a transducer.

By use of a mechanical loader (either motorized or hand crank), rotational force (load) is applied to the torque wrench square drive. This load is very accurately measured by the system’s transducer, which sends data to the digital monitor.

Calibration Terms & Definitions

Calibration Definitions

Accuracy All CDI torque calibration systems have an accuracy of ±0.25% of indicated value, CW & CCW, from 10% to 100% of full scale. DTT testers are ±0.5% of indicated value, CW & CCW, from 10% to 100% of full scale. DTC checkers are ±1% of indicated value, CW & CCW, from 10% to 100% of full scale. A.S.M.E – American Society of Mechanical Engineers. ASME sets codes and standards for mechanical & electronic devices, including torque wrenches. Calibration Arms – Certified arm or wheel that attaches to a transducer for calibration purposes. Calibration – The act of adjusting a torque wrench in order to bring it back within spec. ASME specifications call for wrenches to be calibrated at 3 points; 20%, 60% and 100% of their full scale. Calibration Tray – Certified weight tray used to hang dead weight on a calibration arm for calibration purposes. Certification (or “Cert”) – Written document included with all CDI adjustable torque wrenches and all testers and calibration systems. All certs are traceable to N.I.S.T. Compression Gauge – This is also called a “force gauge.” This is a mechanical or digital device that measures the amount of push, or compression between two forces. Extension Arm – A mechanical arm designed for only the 2000 ft. lb. loader that allows for the testing of torque wrenches over 45” long. Force Arm – System can perform force testing such as push-pull gauges, cable tension meters, and dynamometers with additional components sold separately. 17025 – Laboratories use ISO/ IEC 17025 to implement a quality system aimed at improving their ability to consistently produce valid results. Since the standard is about competence, accreditation is simply formal recognition of a demonstration of that competence. A prerequisite for a laboratory to become accredited is to have a documented quality management system. The usual contents of the quality manual follow the outline of the ISO/ IEC 17025 standard. Joint Rate Simulator – A mechanical device used to test power tools on transducers. The device allows the power tool to spin and simulate soft and hard joints before taking the torque reading. Loader – A loader is the common name of the gearbox device that applies force to the torque wrench for purposes of testing or calibration. The loader applies the load by rotating the transducer while the torque wrench is held stationary. Calibration systems have either a mechanical (hand crank) or motorized loader. Mode (First Peak) – For Micrometer & Split Beam wrenches, captures and holds the applied torque at the “click”. Used for “click” type torque tools. Mode (Peak) – Holds and displays just the maximum torque value applied. Used for digital and dial wrenches, and torque screwdriver testing. Mode (Power Tool) – Displays final peak average torque. Used for power tools. Mode (Track) – Displays continuous real-time torque values as force is applied (similar to dial wrench function). Used for electronic or dial type testing. N.I.S.T. – National Institute of Standards and Technology is a non-regulatory agency of the U.S. Department of Commerce. They are a federal agency that sets standards for weights and measurements in the U.S. All CDI torque products are calibrated with weights and arms that are traceable back to N.I.S.T. NIST Traceable – All weights, arms, and trays are certified and traceable through serial numbers back to equipment that meets N.I.S.T. accuracy standards. Tension Gauge – Also called the “force gauge.”
