Torque Tool
Inspection & Certification
Accredited calibration and inspection of torque wrenches, torque multipliers, hydraulic torque tools, and all torque-applying equipment. Ensuring accuracy, traceability, and full compliance with ISO 6789 and UAE quality management system requirements.
What We Inspect
Torque Tool Types
We provide comprehensive inspection and certification services across a wide range of equipment and systems.
Torque Measurement
Torque measurement services verify that fasteners are tightened to the correct specification using calibrated equipment, preventing under-tightening (joint slippage) and over-tightening (fastener fatigue) per ISO 16047 and assembly requirements. Detailed torque audit reports confirm joint integrity and provide traceability for critical structural connections.
Bolt Tension Testing
Bolt tension testing uses direct-tension indicators, hydraulic tensioners, or ultrasonic bolt measurement to verify that correct preload has been applied and that joint integrity is maintained under service loads per ISO 898-1 and structural bolting standards. Accurate preload confirmation prevents joint slippage, fatigue failure, and unexpected loosening in critical connections.
Fatigue Testing
Fatigue testing subjects fasteners to cyclic loading to evaluate resistance to crack initiation and propagation, confirming suitability for dynamic service environments per ISO 3800 and ASTM E466. Results support service life prediction, maintenance interval planning, and design validation of bolted connections in critical or cyclically loaded structures.
Shear Testing
Shear testing measures the load at which a fastener fails under lateral force, confirming that bolts meet the minimum shear strength of their grade per ISO 898-1 and ASTM F606. Testing validates material properties and heat treatment, ensuring fasteners are fit for purpose in structural shear connections.
Vibration Testing
Vibration testing evaluates a fastener assembly's resistance to loosening under dynamic loading using the Junker method per NAS 3350 and ISO 16130, confirming that selected fasteners and locking features maintain clamp load in service. Results guide the selection of appropriate anti-vibration fastening solutions for high-vibration applications.
Hardness Testing
Fastener hardness testing uses Vickers, Rockwell, or Brinell methods to verify material hardness falls within the specified range for the grade, confirming correct heat treatment and resistance to hydrogen embrittlement per ISO 898-1 and ASTM F606. Out-of-range hardness indicates non-conforming material and triggers batch rejection.
Corrosion Resistance Testing
Corrosion resistance testing of fastener coatings uses salt spray per ISO 9227, humidity cycling, and electrochemical methods to confirm that protective treatments meet specification requirements. Results guide coating selection and inspection intervals for fasteners used in corrosive outdoor, marine, or chemical process environments.
Tightening Procedures Validation
Tightening procedure validation confirms that assembly sequences, torque values, angle-of-turn parameters, and tool types achieve the required preload and uniform load distribution per ISO 5855, EN 1090, and structural bolting standards. Validated procedures provide documented evidence of compliant assembly for quality audits and regulatory acceptance.
Thread Inspection
Thread inspection uses calibrated GO/NO-GO gauges and optical measurement to verify pitch, flank angle, major and minor diameters, and the absence of surface defects per ISO 1502 and ASME B1.13M. Non-conforming threads that could prevent correct engagement or reduce joint strength are identified and rejected before assembly.
Preload Testing
Preload testing directly measures the clamping force developed during tightening using calibrated load-measuring washers, strain gauges, or ultrasonic elongation measurement per ISO 16047 and ASME PCC-1. Accurate preload data confirms the assembly procedure achieves the design target and prevents premature joint failure under service loads.
Breaking Load Test
Breaking load testing applies monotonically increasing tensile force to fasteners until failure, confirming that proof load, yield strength, and ultimate tensile strength meet the requirements of the specified grade per ISO 898-1, ASTM F606, and DIN 267. Batch acceptance testing provides material conformance evidence before installation.
Torque-Angle Relationship Testing
Torque-angle relationship testing plots applied torque against rotation angle during tightening to identify elastic, yield, and plastic zones, enabling accurate angle-controlled assembly per ASME PCC-1 and manufacturer specifications. This technique delivers consistent and reproducible preload, reducing scatter compared to torque-only methods.
Clamp Load Testing
Clamp load testing quantifies the axial clamping force in a fastener assembly using calibrated load cells or instrumented bolts, providing direct verification that the joint has been assembled to the required preload target per ASME PCC-1 and ISO 16047. Measured clamp load data is retained as quality evidence for critical bolted joint assemblies.
Hydraulic Bolt Tension Testing
Hydraulic bolt tensioner calibration verifies that hydraulic tools apply accurate and consistent tensile force to fasteners, ensuring specified preload is achieved per PAS 2034 and applicable pressure equipment standards. Calibration certificates confirm traceability to national measurement standards, supporting compliant assembly of pressure vessel, pipeline, and structural flange joints.
Thorough Examination
What We Inspect On Every Piece of Equipment
Our inspections go beyond visual checks. We follow manufacturer guidelines and international standards to ensure total safety.
Torque Accuracy Verification
Calibration of torque tools at low, mid, and high range points against certified reference transducers traceable to national measurement standards.
Repeatability Assessment
Multiple measurement cycles at each calibration point to assess tool repeatability and identify wear in click mechanisms or transducer elements.
Physical Condition Inspection
Examination of tool body, ratchet mechanism, drive square, scale, and handle for damage that could affect accuracy or safe operation.
Traceability Documentation
Issue of calibration certificates showing measured values, reference standard details, uncertainty statement, and traceability chain to national standards.
Calibration Interval Recommendation
Assessment and recommendation of appropriate recalibration interval based on tool type, usage intensity, and accuracy requirements of the application.

UAE Regulations
Legal Requirements
PPE Inspection inspection is not optional in the UAE. Here's what you need to know.
ISO 9001 & QMS Requirements
Quality management systems certified to ISO 9001 require all measuring and test equipment, including torque tools, to be calibrated at defined intervals with traceable certificates. TSC's calibration services support QMS compliance and third-party audit requirements.
LEEA & Critical Bolting Standards
Critical bolting in lifting equipment, pressure systems, and structural connections requires torque tools to be calibrated to ISO 6789 to ensure joint integrity and safety in accordance with UAE engineering and industry standards.
Calibration Records Retention
Calibration certificates and records for torque tools must be retained as quality records and made available to clients, auditors, and UAE regulatory authorities on request throughout the equipment's service life.
