When the wrench clicks, the designated amount of torque has been applied. Stop pulling. Continuing to pull after the wrench clicks can increase the applied torque to a value that exceeds the engineering specification.

This preset click torque wrench measures and applies torque in the clockwise direction. Using this wrench in the counter-clockwise direction will apply torque, but it will not measure torque because it does not click in the counter-clockwise direction.

How do you know if you have a 6-volt battery/radio wrench or the new A3 battery/radio wrench? A simple way is to look at the part number.

810411 is the SLTC FM A3 50i model.

The 810311 is the SLTC FM 6 volt model.

Application Information

We are announcing the new SLTC 2.4 GHz A3 Preset Clicker-Type Torque Wrench. We kept the flattened case for superior accuracy, reliability, and durability. Customers tell us that this wrench holds calibration better than any other brand.

Full compatibility with Global 8, Global 8-Ethernet, Global 400mp, Global 400, PTV-FM 2.4 GHz, TCV-FM 2.4 GHz, TCV e2, and TCV-Ethernet.

The accuracy of +/- 4% or better of preset value from 20% to 100% of capacity meets or exceeds requirements of ASME B107.300-2010 and ISO 6789.
Excellent audible/tactile impulse when preset torque is achieved.
Error Proofing By Guidance: Monitors time in the “clicked” position to proved “OK/BAD” quality attribute data with every use of the tool.
- Too little time in the clicked position means the tool was likely “jerked”, resulting in either over- or under-torque.
- Correct time in the clicked position means the tool was used properly to transmit the preset torque correctly to the fastener.
- Too much time in the clicked position means the tool was likely pulled past the click and excess torque was applied to the fastener.
- Working with these intelligent tools helps refine eye/hand motor skills and improve performance. This is Error Proofing By Behavior Modification in action.
- The new A3 has a new battery that lasts longer and is easier to change. We also added a new raised LED Fresnel to improve visibility when working in less than optimal positions. The AAA batteries are more readily available than are the 6-volt batteries. The AAA batteries also cost less. Some companies are seeing the savings in battery costs to be substantial. The switch to the AAA battery board is a great idea.

Have existing 6-volt SLTC FM 2.4 GHz wrenches and want to upgrade? No problem. Retro-fit kits are fast and easy to install and are typically completed in less than five (5) minutes. (Order P/N 10615 for wrenches up to 1800 i and P/N 10616 for wrenches with a capacity of 3000i and larger)

A quick note about batteries and our SLTC FM wrenches: the radio in our Exacta Series digital wrenches and our digital torque testers require the use of a NiMH battery. However, the SLTC FM click wrench can use alkaline batteries or the NiMH batteries. For your convenience, we ship our SLTC FM with an alkaline battery (as seen in the photo above) so you can set the wrench, add the battery, and go to work.

Error Proofing From A Different Angle: Definition of error proofing and some observations by W. Edwards Deming.

Finding The Balance: In error proofing "one size fits no one." To find what fits in your organization, start with the fundamental question of "How much responsibility for error proofing should be given to the tool and how much should be operator responsibility?" This section provides more on this concept.

Six Error Proofing Scenarios: Error proofing solutions all have trade-offs. You can have control or you can have flexibility. Rarely do you get both. This page looks at error proofing extremes as well as the middle ground.

How Much Are You Investing In Errors? If your current error proofing system or approach still leaves you with errors you are investing in errors, not error proofing. Error proofing is about quality and it is also very much about dollars and common sense. This page digs into that.

Understanding The Common Centerline: Not having a common centerline is one invisible place where your error proofing approach can introduce errors instead of eliminating them. If you want to know how to calculate a common centerline and why it is important, this page is for you.
