For higher-torque socket fastening in connected assembly workcells, the Cleco 50EPN65HD4 NeoTek Corded Electric Nutrunner delivers a 10.3 – 48.6 ft-lbs torque range with 900 RPM free speed for controlled rundown and final tightening. It’s 1/2″ square drive supports larger compatible sockets than the 3/8″ drive models in the same family, making it a practical choice for heavier brackets, mounts, frames, and mechanical subassemblies that still require precision fastening control.This 50 Series NeoTek pistol nutrunner uses transducer control, which measures torque directly during the fastening cycle for improved feedback and process monitoring. With a 14.0 – 66.0 Nm torque range, 4.72 lb tool weight, and Cleco smart-tool feedback features, the 50EPN65HD4 fits production environments where operators need clear cycle status, fastening traceability, and repeatable torque results across repeated assembly jobs.Type: Corded Electric Nutrunner | Series: NeoTek 50 Series | Control Type: Transducer Control | Configuration: Pistol | Model: 50EPN65HD4 | Torque Range: 14.0 – 66.0 Nm / 10.3 – 48.6 ft-lbs | Free Speed: 900 RPM | Output Drive: 1/2″ Square Drive | Weight: 2.14 kg / 4.72 lb | Length: 11.34 in | Side to Center: 0.87 inFeatures:1 million cycles maintenance-free for reduced service interruptions in production fastening environments.Repeatability and accuracy with 2.0 Cm/Cmk at +/- 7% for controlled assembly processes.Transducer-controlled fastening measures torque directly to support process control and fastening traceability.Configurable LED light rings provide visual feedback for operators during fastening cycles.Tactile and audible operator feedback helps communicate tool status during repetitive assembly work.Programmable multi-function buttons support flexible setup for different station requirements.1/2″ square drive output accepts compatible sockets for higher-torque nut and bolt fastening within the tools rated range.Made in USA: Applications:Automotive and transportation assembly controlled tightening of structural brackets, mounts, supports, and medium-to-higher torque bolted joints.Industrial equipment manufacturing fastening frames, guards, motor mounts, housings, and mechanical subassemblies within the 14.0 – 66.0 Nm range.Agricultural and off-road equipment production socket-driven assembly work where 1/2″ drive tooling is preferred for larger hardware.Machinery and appliance build lines repeated fastening of panels, reinforcements, and mechanical hardware where consistent torque matters.Quality-controlled production cells assembly stations using tool feedback and fastening data to help verify completed rundowns.FAQs:Q: How does the 50EPN65HD4 compare to the 50EPN43GD3?A: The 50EPN65HD4 provides a higher torque range of 14.0 – 66.0 Nm and uses a 1/2″ square drive. The 50EPN43GD3 covers 9.0 – 43.0 Nm with a 3/8″ square drive, so this model is the better fit when the joint requires more torque and larger socket tooling.Q: What does the 1/2″ square drive mean?A: The 1/2″ square drive is the tools output anvil size. It accepts compatible 1/2″ drive sockets, which are commonly used for larger fasteners and higher torque assembly work than smaller 3/8″ drive sockets.Q: Is the 900 RPM speed for tightening or free speed?A: The 900 RPM rating is the tools free speed, meaning the speed before load is applied to the fastener. Actual fastening speed can vary depending on joint type, programmed strategy, torque target, and assembly conditions.Q: Can this nutrunner be used like an impact wrench?A: No. The 50EPN65HD4 is a controlled assembly nutrunner for tightening fasteners to a specified torque range. Impact wrenches are better suited for loosening stuck fasteners, breakaway work, and general repair tasks.Q: Does this tool require compressed air?A: No. This is a corded electric NeoTek nutrunner, so it does not require an air compressor, air hose, or filter-regulator-lubricator setup. .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 SpecificationsSKUTorque RangeWeightLengthSide to CenterMin NmMax NmMin Ft LbMax Ft LbLbkginin30EPN05BD20.94.70.663.472.050.937.760.6430EPN05BDQ0.94.70.663.472.010.918.270.6430EPN12EAQ3.911.62.888.562.201.009.020.6430EPN12FA33.911.62.888.562.160.988.430.6430EPN19FB33.919.02.8814.012.201.008.430.6430EPN26FB35.126.03.7619.182.201.008.430.6450EPN28FD35.628.04.1320.653.481.5810.080.6450EPN43GD39.043.06.6431.723.641.6510.240.7450EPN65HD414.066.010.3348.684.722.1411.340.8750EPN85JD417.084.012.5461.964.892.2211.890.8750EPN125KD425.0123.018.4490.725.782.6212.321.10 (function(){ function initSpecAccordions(){ document.querySelectorAll(“.spec-accordion”).forEach(function(a){ if(a.dataset.specAccordionInit===”true”)return;a.dataset.specAccordionInit=”true”; var b=a.querySelector(“.spec-accordion-toggle”),p=a.querySelector(“.spec-accordion-panel”);if(!b||!p)return; var u=false; function m(){return(a.getBoundingClientRect().width||window.innerWidth)
