Why Mountz Torque Tools Are Trusted by Manufacturers Worldwide

Torque matters more than most people realise. A fastener that is under-torqued can vibrate loose under load. One that is over-torqued can strip threads, crack components, or cause latent failures that only appear once a product is in service. In industries like aerospace, medical, and electronics manufacturing, those failures are not acceptable.

Mountz was founded on a single principle: that precision torque control should be reliable, repeatable, and accessible to any manufacturer that needs it. Since producing the world’s first electronic torque calibrator in the 1960s, Mountz has remained 100% focused on torque — which means every tool, every sensor, and every wrench in the range is engineered with a depth of expertise that generalist tool brands simply cannot match.

Key reasons engineers and quality managers choose Mountz torque tools:

ISO 6789 compliance — Mountz hand torque tools meet or exceed the requirements of ISO 6789-1:2017, the international standard for hand torque tools used in quality-critical assembly
Extended calibration life — Mountz FGA torque screwdrivers stay in calibration up to four times longer than ISO 6789 standards require, reducing downtime and recalibration costs
Cam-over technology — built-in clutch mechanisms disengage automatically at the set torque, eliminating the risk of operator over-torque regardless of skill level
ESD-safe options — ESD-rated torque screwdrivers protect sensitive electronics from electrostatic discharge during assembly
ISO 9001:2015 certified manufacturing — every Mountz product is produced under a certified Quality Management System, ensuring consistency across the entire range

The Mountz Range at Red Box Tools

Mountz Torque Wrenches — A comprehensive range covering click wrenches, cam-over wrenches, and break-over wrenches for manual fastening applications. All products meet or exceed ISO 6789 accuracy requirements. Insulated torque wrench options are also available for electrical assembly environments.

Mountz Torque Screwdrivers — Preset, adjustable, electric, and ESD-safe torque screwdrivers for precision assembly in production and field service environments. The popular FGA adjustable range allows operators to switch torque values quickly without sacrificing accuracy or risking over-torque.

Mountz Torque Analysers and Sensors — Test and verify your torque tools on-site before they go into service. Mountz analysers and sensors support both hand and power tool testing, helping quality teams maintain calibration records and comply with ISO 9001 gauge management requirements without sending tools off-site.

Frequently Asked Questions

What industries use Mountz torque tools? Mountz torque tools are used across aerospace, automotive, electronics, medical device manufacturing, energy, and packaging. Any process that involves tightening fasteners to a specified torque value — whether for safety, compliance, or product quality — is a candidate for Mountz precision torque tools.

What does ISO 6789 mean for torque tools? ISO 6789 is the international standard that defines accuracy and repeatability requirements for hand torque tools used in quality-controlled assembly. A tool that meets ISO 6789 has been tested to deliver consistent torque output within a defined tolerance. Mountz hand torque tools meet or exceed these requirements, and many stay in calibration significantly longer than the standard demands.

Do I need a torque analyser if I already have calibrated torque tools? Yes, in most quality-managed environments. Calibrated tools can drift out of specification through normal use. A Mountz torque analyser allows you to verify tool accuracy on-site before each shift or production run, catching problems before they affect product quality or audit compliance. This is faster and more cost-effective than sending tools to an external calibration laboratory.

What is the difference between a click wrench and a cam-over wrench? A click wrench signals when the target torque is reached with an audible click, but the operator must stop applying force immediately to avoid exceeding the set value. A cam-over wrench uses an internal clutch that physically disengages at the set torque, preventing over-torque regardless of operator technique. Cam-over wrenches are preferred in applications where over-torquing would damage components or void warranties.
