01 / WHY
BEHIND EVERY FAILURE IS INCONSISTENT BOLT LOAD
Leaks. Unplanned shutdowns. Joints that come back apart. Trace them back far enough and you reach the same root cause — the bolt didn't end up carrying the load it was designed to carry.
Get the clamp force right and the joint simply holds. Get it wrong, and no gasket, inspection, or sign-off can save it. Torque accuracy isn't paperwork — it's how you protect people, uptime, and the work.
THE REFRAME
TORQUE IS THE METHOD
BOLT LOAD IS THE GOAL.
Torque is just one way to reach a target — and a lossy one. Most of it is eaten by friction; only a fraction becomes clamp force. That's why two bolts at identical torque can carry completely different loads.
You measured the input. The joint only cares about the output. The LST is built to control the output.
02 / HOW
HOW THE LST DELIVERS CONSISTENT LOAD
Consistency is engineered into the tool — not left to muscle, fatigue, or whoever happened to be on shift.
CONTROL STRETCH
TORQUE + ANGLE
Applies torque, then rotates to a precise angle — controlling bolt stretch directly and cancelling out the friction variable.
MEASURE
TORCSENSE™ TECHNOLOGY
Directly measures torque at the tool in real time — so the value on the screen is the value applied to the bolt.
GUARD THE WINDOW
MONITORED MODES
Monitored Torque and Monitored Angle stop the operation the instant it falls outside the engineered spec window.
REMOVE ERROR
TEMPLATES
Store exact parameters once. Every operator runs the job the same way — no re-keying, no drift, less human error.
RIGHT HANDS
FOUR USER LEVELS
Lock values for operators; open the full menu for engineers. The right control stays in the right hands.
SNUG → TIGHT
RUNDOWN + TORQUE
Spin nuts down fast, then switch to controlled torque for the measured pass — one tool, the whole operation.
THE OLD WAY
Hydraulic Wrenches & Big Wrenches
Pump, hoses, and setup time
Two people on the joint
Result varies by who's swinging it
Brute force and fatigue
No record of what was applied
THE LST WAY
One Person. One Tool
A 9.5 lb tool, carried and run by one operator
Grab and go — no pump, no hoses
Same measured result, every time
Up to 8,000 ft-lbs of controlled torque
Every bolt documented automatically
You don't just save labor — you raise the value of every person on the crew. The tool sets the standard, not the individual. Work done right, the first time, every time.
SPEED COMPOUNDS
BOLTING IS THE START AND THE END OF THE CRITICAL PATH
A turnaround can't begin until the flanges come apart and can't finish until they're buttoned back up. Every minute you save at the joint is a minute off the whole job — at both ends.
CONTINUOUS ROTATION
CONSTANT SPEED. NO RATCHETING
A hydraulic wrench works in strokes — pump, ratchet, reset, repeat — creeping toward target. The LST turns the nut in one continuous rotation at constant speed, reaching target torque in a fraction of the time.
On a single bolt it's seconds. Across a flange, a shift, and a full turnaround, those seconds snowball into hours off the schedule.
HYDRAULIC SETUP · BEFORE A SINGLE BOLT MOVES
- Haul pump, tool & hoses up to the work area
- Run an air supply from the compressor
- Connect, bleed & pressure-test the hoses
- Wait on auxiliary equipment before you start
Waiting on auxiliary gear kills time — and snowballs into an unpredictable tail end.
LST SETUP
CLIP IN A BATTERY. GO UP. PULL THE TRIGGER.
No pump. No hoses. No compressor. One person carries a 9.5 lb tool to any height and starts working — which is exactly what makes work at height practical.
03 / WHAT
A DOCUMENTED RECORD FOR EVERY BOLT
For flange management and QA, the bolt is only half the deliverable. The LST hands you the other half — automatically.
CAPTURED AUTOMATICALLY
Every trigger pull records target & final torque, angle, date, time, pass & bolt number, Job ID, User ID, and an OK / error status.
TWO WAYS OUT
Stream live over Bluetooth to the HYTORC Connect app, or export to a PC by USB as a standard .CSV file.
AUDIT READY
Hand over a joint with a complete, defensible record instead of a clipboard and a signature.
TWO WAYS TO MEASURE TORQUE
A TRANSDUCER MEASURES.
MOTOR CURRENT ONLY
GUESSES
Most electric tools infer torque from how hard the motor is working — an open-loop estimate. The LST carries a built-in transducer that measures torque directly at the drive, in real time. Closed-loop. That difference is everything on a critical joint.
ADVANCE BOLTING, IN PRACTICE
THE DATA ISN'T A BY PRODUCT.
IT'S THE POINT
Every trigger pull records torque and the angle turned past snug. That pairing is what lets you prove consistent bolt stretch — and it unlocks strategies a click wrench never could. Real field use cases below.
OPEN-LOOP
CURRENT-CONTROLLED
Calculates torque from motor power draw.
—Torque is inferred, not measured
—Drifts with temperature, wear & friction
—Cost-effective, but less precise
—No true reading to document or trac
CLOSED-LOOP · TORCSENSE™
TRANSDUCERIZED
A built-in sensor reads torque directly, in real time.
✓Direct, real-time measurement at the drive
✓Ultimate precision, unaffected by the guess
✓Full traceability & digital proof per bolt
✓Industry-4.0-ready tightening strategies
the joint is operation- or safety-critical, where a fastening failure means expensive repairs or real liability — and wherever strict quality control demands full traceability, defined tightening strategies, and digital proof of a correctly torqued joint

ON THE TOOL
EVERYTHING ON ONE SCREEN
Torque, angle, release, fastener type, access level, active template and Job ID — the operator sees the full spec before the trigger is pulled, and a green check confirms every good bolt.
USE CASE · TORQUE + ANGLE MONITORING
CONSISTENT STRETCH ON EVERY BOLT
Torque alone is a lossy proxy — friction eats most of it. But the angle turned after the trigger torque is directly proportional to how far the bolt stretched. Monitor that angle and you're measuring the one thing that matters: preload.
The LST logs the angle-past-snug for every fastener, so you can prove each bolt in the pattern reached the same stretch — not just the same torque reading.
USE CASE · RESIDUAL - TORQUE CHECK
READ THE LOAD ALREADY ON THE BOLT
Need to know if a previously-tightened bolt is still holding? Apply a small angle forward, then reverse, while monitoring torque. The peak torque at the end of the forward rotation reveals the residual load — without over-tightening.
A non-destructive verification the LST can document across an entire flange, giving flange-management teams a defensible before/after record.
MONITORED TORQUE
TORQUE TO TARGET, ANGLE IN-WINDOW
Drives to target torque while watching the angle. Outside the acceptable angle band it flags a re-hit or a loose joint — instantly.
MONITORED ANGLE
ANGLE TO TARGET, TORQUE IN-WINDOW
Turns to a target angle while watching torque. If torque strays past the engineered range before the angle is reached, it stops and reports the fault.
CONFIGURED BY QR
SCAN THE JOB ID. SKIP THE MENU.
Instead of thumbing through the tool menu, generate a QR code per job or joint. Scan it and the tool loads the Job ID and the exact bolting parameters — right operation, right torque, right angle window — in one step.
Fewer keystrokes, zero mis-keys, and the same configuration handed to every operator on the crew.
FROM THE FIELD
"It's lighter than I expected, it's really fool proof, and so simple that anyone can get the job done. The guys are going to be able to work longer and safer — while still getting the job done right."
