If you are looking for a torque wrench calibration service or any torque tool, then welcome to AML Instruments. As an independent calibration specialist company, our engineers have extensive experience in calibrating the various types of torque wrenches. But most importantly we can calibrate your torque wrench at a sensible price and with a quick turnaround alongside fantastic customer service! Our company's success has been built on long term relationships from being on time, reasonably priced and consistently providing quality workmanship. We fully understand that being without your torque devices stops you from potentially completing your work, which is why we offer a fast and reliable turnaround service for calibrations. Free adjustments where possible!
To be as flexible and to continually offer an outstanding calibration service, we have four options.
If minimal disruption to your business is important, then our seasoned engineers will come to you. Meaning your individual torque equipment will be unavailable for less than 30 mins, whilst we calibrate it. An ideal solution for larger quality and inspection departments.
Currently, our mobile team can only calibrate torque wrenches that measure 400 Nm and below. Anything above 400 Nm will have to be calibrated at our laboratory.
Call Tel:01522 789375 to book our onsite calibration service
You can send your torque wrenches and or digital torque wrenches to our laboratory in Lincolnshire. Standard service if you choose this option is 5 working days.
All torque and digital torque wrenches will return with a traceable calibration certificate.
We do not generally arrange collections, but we do arrange the return via UPS
Please contact us today for a quotation for your torque wrenches calibrations you can contact us via Tel: 01522 789375 or use our contact form.
We offer an express 24-hour torque wrench calibration service. This service must be pre booked.
Our While You Wait Service (requires pre-booking) but is there for those in our area to pop in, get their torque wrenches calibrated and be on their way.
An ideal solution for mobile mechanics & service engineers or quality and inspection teams.
Virtually, every testing tool requires calibrating to continue giving accurate readings and perform correctly. Some either forget or are unaware that a torque tool’s internal workings are made up of moving metal components that will wear, break, or crack. Extreme conditions or a severe drop increases the chance of damage, all leading to decreased accuracy. It’s not uncommon to see torque equipment with a 20 or 30% error in their torque readings!
Torque Wrenches are routinely adjusted during the calibration process to bring them back within specification, we always record the before and after adjustment figures on the calibration certificate.
For safety & quality assurance purposes, a torque wrench must be accurate.
The purpose of a torque wrench is to tighten bolts, nuts or screws to a precise torque.
Applying a consistent and accurate torque to a bolt, nut or screw is critical for it to securely hold whatever is in place. It’s important a bolt is not over tightened as it could break or shear. There have been many cases of car wheel nuts being over tightened and wheels falling off at high speed!
Having an experienced team, we can offer calibration on the following torque equipment and hand torque tools:
If you have any of the above hand held torque tools and need an annual calibration service with a traceable calibration certificate, then we would love to hear from you.
You can call our team directly on Tel: 01522 401 375, or use our live chat in the bottom right hand corner of this webpage or use our contact form.
As an experienced calibration company, AML Instruments can offer ISO 6789-1:2017 and ISO 6789-2:2017 compliant checks for the following types of torque tools:
The two standards were conceived by the International Organisation for Standards for Type 1 (indicating) and Type 2 (setting) torque tools.
Most brands will recommend you calibrate your torque wrench yearly or after 5000 cycles. There are situations when this time or number of cycles should be reduced, i.e.,
To be on the safe side, it is recommended you send your torque tools to a calibration technician, as the process will be correctly documented, and he/she will be far more efficient at calibrating.
The cost of our torque wrench and torque screwdrivers calibrations is split into two groups:
Under 400Nm £40 Excl. VAT and return shipping.
401 – 1000Nm £50 Excl. VAT and return shipping.
Our express 24 / 48 service costs and extra 40% and while you wait 50%
Other torque tools are quoted for on a case-by-case basis.
If you have a unique torque tool, please get in contact, as we love a challenge.
The SI unit of measurement for torque is the Newton Meter (Nm). This the force in Newtons at 1 meter from the axis.
Other common units of torque measurement are
Pounds force foot IBF/FT also known foot pound ft/lb
Kilogram – force centimetre kgf/cm
Deci Newton metre dN/m
