Built from steel with a zinc gold chromate finish, it features a 3\/8-16 threaded shank with a 0.75-inch thread length and a knurled knob for secure manual actuation. The spring-loaded plunger delivers an initial end force of 0.5 pounds and a final end force of 3 pounds, providing reliable retention across a range of clamping and locating tasks. The locking element holds the plunger in the retracted position, allowing hands-free operation during part loading or fixture setup. Mechanical contractors, maintenance technicians, and machine builders install this type of hardware in jigs, fixtures, and panel assemblies.\u003c\/p\u003e\u003cp\u003eThe KLS-3-PT-G suits light-duty positioning and locking tasks in jigs, fixtures, enclosures, and machine frames where a threaded plunger with manual override is required. The 3\/8-16 thread size is compatible with standard tapped hole patterns common in fabricated steel and aluminum assemblies. The knurled knob style provides grip without the need for tools, making it appropriate for frequently accessed access panels or adjustment points in production and service environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLocking plunger element holds retracted position for hands-free part handling\u003c\/li\u003e\n\u003cli\u003eKnurled knob style allows tool-free manual actuation\u003c\/li\u003e\n\u003cli\u003eSpring force range: 0.5 pounds initial to 3 pounds final end force\u003c\/li\u003e\n\u003cli\u003eSteel construction with zinc gold chromate finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003e3\/8-16 thread size fits standard tapped holes in steel and aluminum assemblies\u003c\/li\u003e\n\u003cli\u003eCompact plunger projection of 0.22 inches for space-constrained applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or drop-in component for industrial jigs, fixtures, and mechanical assemblies requiring a 3\/8-16 locking knob handle plunger with a 0.75-inch thread length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a properly tapped 3\/8-16 threaded hole in the mating component. Thread the plunger in by hand to start, then tighten to the appropriate engagement depth using the knurled knob or a suitable wrench on the shank if access allows. Ensure the plunger axis aligns with the locating hole or detent to avoid side-loading the spring mechanism. Disconnect or de-energize any associated equipment before servicing plungers in powered assemblies.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Type\u003c\/strong\u003e: Locking\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Plunger Diameter\u003c\/strong\u003e: 0.185 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.186 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.22 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Length\u003c\/strong\u003e: 1.26 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\/Shoulder\u003c\/strong\u003e: 0.97 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.29 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKnob Style\u003c\/strong\u003e: Knurled\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: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: KLS-3-PT-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51716477813042,"sku":"KLS-3-PT-G","price":17.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dad0644d1d5e6b3abb67ac871051f114.jpg?v=1788526654","url":"https:\/\/voomisupply.com\/products\/gibraltar-kls-3-pt-g-locking-knob-plunger-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
