Built for controlled fastening in production assembly environments, the Cleco 35PTHHA403 H Series Shut-Off Hydraulic Pulse Tool combines a 3/8″ square drive, 4,000 RPM free speed, and a manufacturer-published 14.825.8 ft-lbs torque range for tightening M10-class fasteners where repeatability matters. Its hydraulic pulse mechanism delivers torque through short oil-cushioned pulses, helping reduce the reaction force transferred to the operator compared with conventional impact-style fastening. The shut-off function stops the rundown at the preset torque, supporting consistent assembly results across repeated cycles.The pistol grip layout gives operators a familiar trigger-style tool for bench assembly, fixture work, and horizontal fastening tasks. As part of Clecos H Series 4120 Nm shut-off pulse tool range, the 35PTHHA403 is intended for manufacturing teams that need low-reaction fastening, production repeatability, and pneumatic tool simplicity. With a 2.45 lb tool weight, 1/4″ air inlet, 15.90 SCFM air consumption, and 1/2″ recommended hose I.D., this model should be matched to the plant air system, FRL setup, and required joint torque before being placed into service.Type: Shut-Off Hydraulic Pulse Tool | Series: H Series | Model: 35PTHHA403 | Grip Style: Pistol Grip | Drive Type: Square | Drive Size: 3/8″ Square | Torque Range: 14.825.8 ft-lbs / 2035 Nm | Free Speed: 4,000 RPM | Fastener Capacity: M10 | Weight: 2.45 lb / 1.11 kg | Air Inlet: 1/4″ | Air Consumption: 15.90 SCFM | Recommended Hose I.D.: 1/2″Features:Hydraulic pulse fastening helps limit reaction force during repetitive tightening operations.Shut-off model stops the tool at the preset torque, supporting repeatable fastening in production environments.Inertia shut-off system contributes to controlled tool operation across repeated rundowns.Efficient 3-chamber air motor supports consistent pneumatic performance during assembly use.External speed control allows the tool to be adjusted for the application without changing the basic tool configuration.Oil-less blades reduce routine lubrication requirements inside the motor assembly.Reversible torque signal port supports integration with compatible assembly tooling setups where torque signal feedback is required.Low noise level helps make the tool suitable for multi-station production areas.Applications:Automotive assembly tightening M10 fasteners on brackets, subassemblies, interior structures, and light chassis-related components.Industrial manufacturing repeatable bolt rundown in pneumatic workcells, fixture stations, and assembly benches.Appliance and equipment production controlled fastening where consistent torque and reduced reaction force help maintain assembly quality.Aerospace and transportation assembly repetitive fastening tasks where tool weight, reaction control, and torque range must be matched to the joint.MRO tool cribs replacement or standardization tool for facilities already using Cleco H Series hydraulic pulse tools.FAQs:Q: What is the torque range of the Cleco 35PTHHA403?A: The manufacturer-published torque range is 14.825.8 ft-lbs, or 2035 Nm. Final torque should always be verified on the actual joint using your plants torque audit process.Q: What does shut-off mean on this Cleco pulse tool?A: Shut-off means the tool is intended to stop when the preset torque is reached. This helps improve fastening consistency compared with tools that rely only on operator trigger control.Q: What is a hydraulic pulse tool used for?A: Hydraulic pulse tools are used for repetitive tightening where reduced reaction force and repeatable torque are important. They are commonly used in production assembly rather than high-breakaway service work.Q: What socket type does this model use?A: The 35PTHHA403 uses a 3/8″ square drive, so it accepts compatible 3/8″ square-drive sockets rated for the fastening application.Q: Is this tool for removing rusted bolts or lug nuts?A: No. This model is a controlled assembly fastening tool, not a general-purpose impact wrench for breakaway torque. For removal work, choose an impact wrench matched to the required breakaway torque and socket drive size. .spec-accordion{width:100%;max-width:1200px;margin:1em auto;font-family:”Montserrat”,Arial,sans-serif;box-sizing:border-box} .spec-accordion *{box-sizing:border-box} .spec-accordion-toggle{width:100%;display:flex;justify-content:center;align-items:center;position:relative;background:#444;color:#fff;border:0;padding:14px 48px;font-family:”Bai Jamjuree”,Arial,sans-serif;font-size:16px;font-weight:700;text-transform:uppercase;cursor:pointer;text-align:center} .spec-accordion-toggle::after{content:”+”;font-size:22px;position:absolute;right:18px} .spec-accordion.open .spec-accordion-toggle::after{content:””} .spec-accordion-panel{display:none!important;width:100%;padding:16px 0 0} .spec-accordion.open .spec-accordion-panel{display:block!important} .spec-accordion-panel[hidden],.spec-accordion:not(.open) .spec-accordion-panel{display:none!important} .spec-table-wrapper{width:100%;max-width:1200px;margin:0 auto;overflow-x:auto;overflow-y:hidden;-webkit-overflow-scrolling:touch} .spec-table{width:100%!important;max-width:1200px;min-width:100%;margin:0 auto;border-collapse:collapse;table-layout:auto;font-family:”Montserrat”,Arial,sans-serif;font-size:12px;color:#000} .spec-table th{background:#444;color:#fff;text-transform:uppercase;font-family:”Bai Jamjuree”,Arial,sans-serif;font-weight:700;font-size:11px;padding:8px 6px;border:1px solid #ddd;text-align:center;line-height:1.15;white-space:nowrap} .spec-table td{padding:6px;border:1px solid #eee;text-align:center;line-height:1.15;white-space:nowrap} .spec-table .long-text{white-space:normal} .spec-table tbody tr:nth-child(even){background:#f7f7f7} .spec-table tbody tr:hover{background:#e5e5e5} .spec-table a{color:#0066cc;text-decoration:none;font-weight:600;background:transparent;padding:0;border-radius:0;box-shadow:none} .spec-table a:hover{text-decoration:underline} .group-row td{background:#444;color:#fff;font-family:”Bai Jamjuree”,Arial,sans-serif;font-weight:700;text-transform:uppercase;text-align:left} @media(max-width:640px){.spec-accordion,.spec-table-wrapper,.spec-table{width:100%;max-width:100%}.spec-accordion-toggle{font-size:14px;padding:13px 48px}} .spec-accordion.is-mobile-table .spec-table-wrapper{overflow-x:visible!important;overflow-y:visible} .spec-accordion.is-mobile-table .spec-table{width:100%;max-width:100%;min-width:0!important;border:0} .spec-accordion.is-mobile-table .spec-table thead{display:none!important} .spec-accordion.is-mobile-table .spec-table,.spec-accordion.is-mobile-table .spec-table tbody,.spec-accordion.is-mobile-table .spec-table tr,.spec-accordion.is-mobile-table .spec-table td{display:block;width:100%} .spec-accordion.is-mobile-table .spec-table tr{margin-bottom:14px;border:1px solid #ddd;background:#fff} .spec-accordion.is-mobile-table .spec-table tbody tr:nth-child(even),.spec-accordion.is-mobile-table .spec-table tbody tr:hover{background:#fff} .spec-accordion.is-mobile-table .spec-table th,.spec-accordion.is-mobile-table .spec-table td{white-space:normal!important} .spec-accordion.is-mobile-table .spec-table td{display:flex;justify-content:space-between;gap:14px;text-align:right;border:0;border-bottom:1px solid #eee;padding:10px 12px;font-size:13px;word-break:break-word} .spec-accordion.is-mobile-table .spec-table td::before{content:attr(data-label);font-weight:700;text-transform:uppercase;color:#444;text-align:left;flex:0 0 46%} .spec-accordion.is-mobile-table .spec-table td>a{word-break:break-word;background:transparent} .spec-accordion.is-mobile-table .group-row td{text-align:center;background:#444;color:#fff} .spec-accordion.is-mobile-table .group-row td::before{content:none} Available Variations and SpecificationsSKUOutput DriveTorque RangeFree SpeedWeightAir ConsumptionMin Ft LbMax Ft LbMin NmMax Nmr/minLbNPTHose I.D.Scfm7PTHH35Q1/4 Quick Change2.955.24735001.741/43/87.0611PTHH3533/8 Square Drive4.438.161135001.831/43/87.0611PTHH35Q1/4 Quick Change4.438.161135001.871/43/87.0620PTHH4033/8 Square Drive7.414.8102040001.91/41/28.7020PTHH40Q1/4 Quick Change7.414.8102040001.921/41/28.7035PTHH4033/8 Square Drive14.825.8203540002.451/41/215.9035PTHH40Q1/4 Quick Change14.825.8203540002.311/41/215.9035PTHHA4033/8 Square Drive14.825.8203540002.451/41/215.9055PTHH4033/8 Square Drive22.140.6305540002.541/41/215.9055PTHHA4033/8 Square Drive22.140.6305540002.671/41/215.9080PTHH3541/2 Square Drive36.959508035003.091/43/819.4080PTHHA3541/2 Square Drive36.959508035003.311/43/819.40120PTHH3041/2 Square Drive55897512030003.753/81/219.40120PTHHA3041/2 Square Drive55897512030003.863/81/219.40 (function(){ function initSpecAccordions(){ document.querySelectorAll(“.spec-accordion”).forEach(function(a){ if(a.dataset.specAccordionInit===”true”)return;a.dataset.specAccordionInit=”true”;
