FREQUENTLY ASKED QUESTIONS ABOUT
BATTERY TORQUE WRENCHES
What is the maximum torque output of Boltorq cordless battery wrenches?
The BTB series provides torque capacities ranging from 100 Nm up to 4000 Nm across 3/4″ and 1″ square drive configurations.
What are the accuracy and repeatability ratings of the BTB series?
Boltorq BTB lithium-ion torque wrenches deliver an output torque accuracy of +-5% and a repeatability of +-2%.
Can torque data be exported for quality compliance records?
Yes. BTB wrenches feature an integrated output torque report export function and support optional Bluetooth and WiFi connectivity for smart socket data transmission.
How does the automatic reaction arm feature function?
Once the target torque value is reached, the wrench automatically reverses slightly to release reaction arm pressure, allowing the operator to lift the tool cleanly without binding.
How can I request a quote or demonstration?
Contact our engineering and commercial team directly at sales@boltorq.com or call +91 98927 03895.
What are the primary advantages of high-voltage brushless DC motors in BTB battery torque wrenches?
Brushless DC motors operate without carbon brush wear or electrical sparking, delivering higher energy efficiency, reduced heat generation, and extended motor life under continuous high-load field torquing.
How does the automatic reaction arm release mechanism improve site efficiency?
After reaching the target torque preset, the BTB system automatically executes a slight micro-reverse stroke to release wind-up tension in the planetary gearbox. This retracts the reaction arm smoothly from adjacent flange bolts, preventing tool binding and speeding up bolt-to-bolt transfer times.
What digital connectivity options are supported on Boltorq BTB series wrenches?
The BTB controller features a high-definition color LCD screen for selecting working modes and includes USB torque report exports. Optional Bluetooth and WiFi modules enable seamless integration with smart torque sockets for real-time digital job logging.
What drive shaft sizes and models are available in the BTB cordless lineup?
Compact models feature 3/4 inch square drive shafts (BTB500, BTB700, and BTB1400 up to 1400 Nm), while heavy-duty models feature 1 inch square drive shafts (BTB2000, BTB3000, and BTB4000 up to 4000 Nm).
