PCS is your source for quality torque wrench calibration with the fastest turnaround time in the country! With our highly trained staff, we have the capability to calibrate any type of torque wrench including click type torque wrenches, digital torque wrenches, torque screwdrivers, manual torque drivers and automatic torque drivers ranging up to 1100 ft/lbs. Some of the brands we regularly calibrate include Snap-on, CDI, Mountz, Tonichi, Proto, Craftsman and many others. Our high precision “Norbar Pro-Test” torque calibration system has been retrofitted to provide on-site torque wrench calibration at your facility. We also provide ISO 17025 Accredited calibration services for vertical and horizontal torque testers and torque multipliers. Torque testers and multipliers are calibrated with the use of dead weights and specialized torque arms which are customized to fit most manufacturers and models. Calibration of these torque instruments can also be performed both in our environmentally controlled laboratory and on-site at your facility. Please contact PCS today and one of our trained specialists will assist you with your torque calibration needs!
We are an authorized distributor of and can supply you with any new torque instruments you may need!
The purpose of a torque wrench is to apply the correct amount of torque to tighten a fastener such as a nut, bolt or screw. Torque wrenches were originally used by municipalities to prevent over-tightening of nuts and bolts on water and steam pipes in the early 20th century. The basic design of the torque wrench has evolved greatly over the years to fit many different types of applications. The torque wrench is now a commonly used tool in industries around the world, including manufacturing, construction, maintenance, aerospace and transportation. Controlling the accuracy of applied torque is a vital task for a wide range of processes found in industries from manufacturing to aerospace. Companies must be assured that torque specifications are met during their manufacturing processes to ensure the quality and, most importantly, the safety of their product. A rigid and sustained calibration program is essential to maintain this ever important goal.
There are several types of torque wrenches and each type is available in many different sizes and designed to suit a wide range of torque specifications. Click type, slip type and break type are three basic styles of torque wrenches:
A preset torque wrench is designed to apply a single specific torque value. Some preset torque wrenches have no external scale but are internally adjustable within a specified range and come with a special tool to make the adjustment. Other preset torque wrenches, such as a T handle or T bar are more simplistic and are not adjustable. Adjustable torque wrenches have an external scale near the handle showing the available range in increments of the measuring unit such as foot lbs (ft/lbs). The handle is turned until line or arrow meets up with the desired amount of torque. Common units of measure for torque wrenches are inch pounds (in/lbs), foot pounds (ft/lbs), Newton meters (Nm), centimeters per inch (cm/in), kilogram-force per centimeter (kgf/cm) and ounces-force per inch (ozf/in).
Torque wrenches should be checked and re-calibrated often to compensate for wear or defective parts. Any adjustable torque wrench should be stored at 20% of the full scale value of the range to prevent damage to internal parts. Most manufacturers recommend calibration of a torque wrench after every 5000 cycles or 1 year. However, process accuracy requirements may dictate more frequent calibration. A “cycle” of a torque wrench is completed each time a torque wrench is used to meet the amount of torque it has been set to.
At PCS, we provide on-site calibration services to customers residing in Tennessee, Virginia, Alabama or Kentucky. If your establishment is near one of the following locations, we can perform your required torque calibration services on-site:
Contact us today to schedule an appointment.
All calibrations are traceable to the SI through NIST, (National Institute of Standard and Technology) and include “long form” calibration certificates with as-found/as-left data. ISO/IEC 17025 accredited calibration is provided upon customer request. PCS also offers a web based calibration interface which provides our customers access to electronic copies of their calibration certificates which can be viewed or printed as needed. Standard turnaround time is 24- 48 hours.
