Torque Calibration Services in Walcott, ND

J&J Calibration Service Inc. provides specialized torque calibration services to keep your torque tools accurate and reliable. From delicate torque screwdrivers used in electronics to heavy-duty hydraulic torque wrenches for industrial bolting, we calibrate the full spectrum of torque equipment. Based in Walcott, ND, J&J is the region’s trusted source for ISO/IEC 17025 accredited torque calibration – ensuring your tools meet manufacturers’ specifications and industry standards. As a full-service calibration lab in North Dakota (and part of the Accredited Labs network), we deliver both local convenience and top-tier expertise. Our technicians understand that accurate torque directly impacts product quality and safety; we use precise methods to verify your tools so you can fasten with confidence, avoid under/over-tightening, and stay compliant with any required standards.

Capabilities Overview

• Broad Torque Range: We can calibrate torque tools across a very wide range – from just a few inch-ounces of force up to thousands of foot-pounds. Our laboratory torque standards include reference torque transducers and lever-arm systems that cover both low-torque instruments (like small dial torque screwdrivers) and high-capacity devices (like hydraulic torque wrenches up to 10,000 ft-lbs). This broad capability means we can handle virtually any torque application, big or small.
• Static and Dynamic Calibration: We perform calibrations according to the tool type. For click-type and dial torque wrenches, we do multiple runs at various settings to ensure accuracy and repeatability. For continuous tools (like torque screwdrivers or electric torque drivers), we use static transducers to verify their output at different speeds/shut-off settings. Our full-service torque facility is equipped to test both clockwise and counter-clockwise directions, and we can also test tools under dynamic conditions if required (to simulate real-use).
• Repair and Adjustment: If a torque tool is out of tolerance, our technicians can often adjust it on the spot and verify it again – ensuring it’s back within spec before returning it to you. We also provide basic maintenance on torque tools (cleaning, lubrication of wrench mechanisms, etc.) as needed to guarantee proper operation. Our fast, efficient calibration and repair process means minimal downtime for your critical torque tools.
  
  

Equipment Types Serviced

We calibrate essentially all types of torque tools and equipment, including:

• Torque Wrenches: Click-type, dial-indicating, and digital torque wrenches of all sizes. This ranges from small inch-pound wrenches (for precision assembly) up to large 3/4" or 1" drive torque wrenches used in heavy equipment maintenance. We cover ranges from as low as 5 in-lbs up to 2,000 ft-lbs or more.
• Torque Screwdrivers: Small torque screwdrivers (both dial and preset clutch types) used for electronics and delicate assemblies. These are calibrated in inch-ounces or low inch-pounds to ensure accuracy in tightening tiny fasteners.
• Electronic & Hydraulic Torque Tools: Electric torque tools (battery or corded) and pneumatic torque drivers, which often have shut-off or stall torque features. We verify their output torque at various settings. Hydraulic torque wrenches and torque multipliers are also calibrated, often at high values (we can accommodate tools up to 10,000 ft-lbs by using our high-capacity torque transducers and loaders).
• Torque Testers and Transducers: Bench-top torque analyzers/testers and torque transducers used for quality control. We calibrate these reference devices so that you can use them to check tools internally with confidence. If you have a torque tester in your tool crib (e.g., for daily verification of wrenches), we will ensure its readings are accurate across its range.
• Specialized Torque Devices: This includes things like make/break units (used in oilfield or industrial bolting) which measure the torque to break a fastener loose, as well as torque calibration of tools on fixtures or in-line sensors. We also perform torque auditing services – for example, checking bolted joints with a torque auditor wrench to validate assembly processes, if needed.

Accreditation & Standards Compliance

Our torque calibration service is ISO/IEC 17025 accredited, reflecting our technical competence in this field. We follow international and manufacturer-specific standards such as ISO 6789 (for hand torque tools) to ensure calibrations meet the proper methods and tolerances. Our reference torque transducers are regularly calibrated and are traceable to national standards (NIST), providing an unbroken chain of accuracy. When your torque tools are calibrated by J&J, you receive a Calibration Certificate that details the target values, actual readings, deviations, and uncertainty for each test point. This documentation demonstrates compliance for audits (for example, ISO 9001 or aerospace NADCAP requirements) and ensures your quality department has the records needed. We maintain data on your tools’ performance over time, helping you identify if a wrench is drifting out of tolerance over successive calibrations. All calibrations are done with an eye on safety and reliability – a properly calibrated torque tool means tightened bolts stay secure, and we take that responsibility seriously by adhering to the highest quality standards.
