ENGINEERED FOR RIGOROUS INDUSTRIAL TORQUE COMPLIANCE.
Boltorq manual torque wrenches are designed to deliver exact clamping force across a wide range of mechanical and structural bolting applications:
Bi-Directional Measurement & Ergonomic Handle Construction
Operates smoothly in both clockwise and counter-clockwise directions with high-precision internal ratcheting. Non-slip, heavy-duty handle geometry reduces operator strain and fatigue during continuous manual operations.
Multi-Unit Unit Conversion
The BT-HD digital system supports instant switching across N.m, lb.ft, lb.in, and kg f.m.
Pre-Set Audible & Visual Alarm
Prevents over-torquing on critical flange joint bolts via an integrated LED light and audible buzzer alarm.
Peak Hold & Tracking Modes
Allows engineers to capture maximum applied torque values or monitor real-time torque build-up during joint assembly.
ESSENTIAL TORQUE TOOLS FOR HEAVY MANUFACTURING & FIELD WORK.
Boltorq manual torque wrenches are built to meet the demanding bolt-tightening standards of heavy manufacturing, infrastructure erection, and plant maintenance operations worldwide. By delivering certified torque accuracy across high-vibration joints and critical structural connections, our tools safeguard equipment integrity, eliminate joint failure risks, and keep continuous industrial operations compliant with strict international engineering standards.
Structural & PEB Erection
Tightening high-strength friction grip (HSFG) bolts on steel buildings and bridge girders.
Heavy Automotive & Machinery
Applying exact factory torque specs on engine casings, drive shafts, and heavy equipment assemblies.
Refinery & Petrochemical Maintenance:
Conducting routine bolt checks on pipe flanges, valve bonnets, and heat exchanger covers.
FREQUENTLY ASKED QUESTIONS ABOUT
MANUAL TORQUE WRENCHES
What is the maximum torque capacity available in Boltorq manual wrenches?
Boltorq offers manual torque wrenches up to 600 Nm capacity in the BT-H General Mechanical series, and up to 2000 Nm in the BT-HD Digital series.
What is the working accuracy of the BT-H series mechanical wrench?
The BT-H series provides high operational smoothness with a guaranteed working torque accuracy of+-3%.
How do I select between a Digital (BT-HD) and Mechanical (BT-H) wrench?
Choose the BT-HD digital series when you require data recording, peak hold logging, unit conversion, and visual/audible alarms. Choose the BT-H series for rugged, heavy-duty mechanical click feedback in harsh field environments.
How can I request a quote or calibration certificate?
Email our commercial desk directly at sales@boltorq.com or call +91 98927 03895.
What is the mechanical working accuracy of Boltorq BT-H click-type wrenches?
Boltorq BT-H heavy-duty mechanical wrenches deliver a verified working accuracy of +-3% across bi-directional operations (clockwise and counter-clockwise), built with high-strength alloy steel to prevent torque drift over continuous industrial usage cycles.
How do Peak Hold and Tracking modes function on BT-HD digital wrenches?
Tracking mode displays real-time torque values as force is applied against the fastener, while Peak Hold mode captures and locks the maximum applied torque value on the LCD screen so engineers can inspect and verify final tightening results.
What torque unit conversions are supported by the BT-HD digital controller?
Operators can switch instantly between four standard measurement units directly on the digital display: Newton-meters (N.m), Foot-pounds (lb.ft), Inch-pounds (lb.in), and Kilogram-force meters (kgf.m).
How do audible and visual pre-alarms prevent fastener failure?
As the operator approaches the pre-programmed target torque threshold, built-in LED warning lights and a distinct buzzer alarm alert the technician to stop pulling, effectively eliminating human error and over-torquing on high-vibration structural joints.
