Erection crews judge a tool by two things: whether it shifts the bolt, and whether you can still hold it after an hour overhead. The JP-BS35X is specified around both. Its 350 N·m output covers the M8–M20 window that scaffolding couplers, base plates, guardrail fixings and light steel connections live in, and the bare tool weighs 1.205 kg — light enough to work one-handed from a board with the other hand on the tube.
Torque reaches the fastener through a 1:7 reduction on a double-bearing shaft, so hammer loads stay concentric instead of wobbling the socket off the nut. The output spindle is tungsten steel seated in an all-aluminium head, a combination chosen for hardness and heat tolerance; the head itself is sealed, which matters when you are cutting core holes and the air is full of concrete dust.
Two 2000mAh packs and a charger come in the case, enough to keep a small crew rotating batteries through a shift, and the variable trigger lets you start a nut by hand-slow before leaning into the full 2530 r/min. Forward and reverse sit under the thumb, so the same gun that erects in the morning strips out in the afternoon.
From scaffold couplers and handrail clamps to M20 base and connection bolts — one gun handles the sizes a site crew meets every day.
A geared 1:7 drive on double bearings keeps hammer loads centred, so the socket stays square on the nut instead of cam-out.
Brushless copper-wound motor runs cooler and converts more charge into torque — suited to continuous bolting rather than occasional use.
Hardened tungsten-steel output shaft in an aluminium gear case stands up to grit, knocks and weather on open sites.
Swap direction without changing grip: run couplers down in the morning, back them off during strip-out with the same tool.
The trigger feathers from a creep that finds the thread to a full-speed run-down, then stops the instant you let go.
Sealing keeps cutting dust and light rain out of the mechanism while rear vents carry motor heat away from the housing.
1.205 kg bare with a non-slip rubber grip, LED work light and a compact body that fits between tubes and inside steel frames.
No trading company sits between the factory and your container, so pricing reflects what the tool costs to build.
Every wrench completes a torque-verification cycle, drop test and battery discharge check, recorded against its serial.
Batteries, charger and case ship together, so a team is productive the day the box lands rather than hunting accessories.
Anvils, switches, grips and battery terminals are replaceable items we keep on the shelf after a model run ends.
Yes — M8 to M20 is the rated working range, which covers scaffold couplers, guardrail fixings, base plates and light steel connections. As with any impact tool, final tensioning to an engineer's specified torque should be confirmed with a calibrated wrench.
The brushless motor is designed for continuous duty and runs cooler than a brushed equivalent, while the vented housing sheds heat during long runs. Two 2000mAh packs in the kit let a crew rotate batteries so the tool keeps working while a pack charges.
At 1.205 kg without the battery it is manageable one-handed, and the compact body fits between scaffold tubes and inside steel frames. The rubber grip and LED light help when you are working above shoulder height in poor light.
The head is sealed against dust and moisture ingress and the housing vents exhaust away from the motor. Wipe the tool down at the end of a wet day and store it in the case; keep batteries dry and out of standing water.
With a 1/2" drill chuck fitted it will drive twist bits in steel, timber and blockwork, which saves carrying a second tool for incidental holes. Impact-rated sockets and adapters cover other fastener sizes.
The standard kit contains the wrench, two 20V 2000mAh packs, a charger and a carrying case. Additional batteries can be supplied with the order so larger crews keep a spare on charge — confirm quantities when you order.
