The plunger features a 1\/4-20 thread size with a 0.4-inch thread length and a countersunk knob style that sits flush when fully engaged. Built from steel with a zinc gold chromate finish, it delivers corrosion resistance in light-duty environments. The spring-loaded mechanism provides an initial end force of 1 pound, ramping to a final end force of 4 pounds, giving technicians positive tactile feedback during installation and adjustment. Maintenance techs, machine builders, and millwrights commonly install this type of component during equipment assembly or field service.\u003c\/p\u003e\u003cp\u003eThis plunger is suited for use in light industrial machinery, enclosures, fixtures, and equipment panels where a fast-acting, hand-operated locking mechanism is needed. The countersunk knob design is particularly useful in tight-clearance layouts where a protruding knob would interfere with adjacent components. The 1\/8-inch hex size allows for tool-assisted tightening when hand torque is insufficient. Typical applications include panel latching, slide positioning, and tool-holder indexing in manufacturing and assembly environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLocking plunger type with positive lock engagement for secure hold in indexed positions\u003c\/li\u003e\n\u003cli\u003e1\/4-20 thread size with 0.4-inch thread length for standard tapped-hole installation\u003c\/li\u003e\n\u003cli\u003eCountersunk knob style suits low-clearance and flush-mount panel applications\u003c\/li\u003e\n\u003cli\u003eSteel construction with zinc gold chromate finish for light corrosion resistance\u003c\/li\u003e\n\u003cli\u003eSpring end force range of 1 pound initial to 4 pounds final for consistent tactile feedback\u003c\/li\u003e\n\u003cli\u003e1\/8-inch hex drive allows tool-assisted installation or removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-install locking handle plunger for equipment and fixtures using a standard 1\/4-20 tapped mounting hole.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by threading the plunger body into a 1\/4-20 tapped hole by hand, then tightening with a 1\/8-inch hex key as needed. Always de-energize or lock out equipment before servicing any indexing or positioning hardware in mechanical assemblies. Verify thread engagement depth against the 0.4-inch thread length to avoid bottoming out in blind holes. Follow applicable machinery safety standards and the equipment manufacturer guidelines during installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Length\u003c\/strong\u003e: 0.805 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.123 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 4 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Type\u003c\/strong\u003e: Locking\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKnob Style\u003c\/strong\u003e: Countersunk\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Gold Chromate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GIBRALTAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HDLS-1-PT-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51699726516530,"sku":"HDLS-1-PT-G","price":23.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5b7d7bb1d068acf6e77fda8aa3c02661.jpg?v=1788379924","url":"https:\/\/voomisupply.com\/products\/gibraltar-hdls-1-pt-g-locking-knob-handle-plunger","provider":"Voomi Supply","version":"1.0","type":"link"}
