Mountz Inc. features an experienced calibration and repair staff. Our trained technicians can calibrate and repair most any tool. Mountz provides rapid service with quality that you can trust as we offer two state-of-the-art calibration lab and repair facilities that can calibrate up to 20,000 lbf.ft.

With 50 years of experience, Mountz’s in-depth knowledge of torque is reflected in our tool’s craftsmanship and our ability to provide solutions to both common and uncommon torque applications. We perform calibrations in accordance with ANSI/NCSL-Z540. Mountz is dedicated solely to the manufacturing, marketing and servicing of high quality torque tools.

Establish a Calibration Program Calibration is fine-tuning the torque control process in a production environment. Calibration should be checked periodically to determine whether torque tools are operating at their proper settings. Many tools don't have a locking device, and users may easily change their torque settings. When this happens, the tool falls out of adjustment.

A regularly scheduled calibration program enables quality control personnel to correct divergence from proper settings, whether it's because of normal slippage over time or because of adjustments to the tool. Begin by setting a calibration interval initially based on severity of the application and the tool manufacturer's recommendations. If the applied torque values are out of range, cut the calibration interval in half and re-test the tools.

Preventive Maintenance To maintain consistent accuracy, torque tools must be checked periodically for wear or defective parts. A properly structured preventive maintenance program optimizes tool performance and reduces unexpected downtime, thereby saving time and money in the long run.

Monitoring the number of cycles per day and total hours that a tool is used is the most accurate way to establish proper maintenance intervals. It is recommended that tools be serviced after 100,000 cycles, or if an inspection reveals old or dry grease, parts that show signs of excessive wear, or loose screws and bolts. Mountz is an ISO 9001 certified and ISO 17025 accredited company. To view certificates: ISO 9001 ISO 17025 for Foley, AL and for San Jose, CA

In order to maintain accuracy, it is crucial that torque control measuring equipment be calibrated regularly.

We recommend a general six (6) month calibration interval. However, it is the user’s organization that must determine suitable intervals based upon equipment performance, application, degree of usage and management objectives.

All calibration certificates from Mountz are issued with a 6-month interval and due date unless otherwise specified at time of order.
