It features a 1\/4-20 thread with a 0.5-inch thread length and a non-locking steel plunger with a maximum diameter of 0.123 inches. The spring delivers 1 pound of initial end force and 4 pounds of final end force, making it well-suited for repeatable, hand-adjusted positioning tasks. Machinists, maintenance technicians, and assembly professionals install this type of component into threaded housings or fixtures where controlled plunger engagement is needed without tooling.\u003c\/p\u003e\n\u003cp\u003eThis spring plunger is used in jigs, fixtures, machine tool components, and light fabrication setups where a hand-adjustable, non-locking index point is required. The knurled knob allows tool-free adjustment by hand, which suits production environments where frequent repositioning occurs. The steel body with zinc gold chromate finish offers corrosion resistance suitable for general shop and industrial environments. It ships as a single unit and is intended for direct installation into a pre-tapped 1\/4-20 threaded hole.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNon-locking plunger type allows free retraction without a separate release step\u003c\/li\u003e\n  \u003cli\u003eKnurled knob head enables tool-free hand adjustment in the field\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc gold chromate finish for general corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 thread size fits standard pre-tapped holes in fixtures and jigs\u003c\/li\u003e\n  \u003cli\u003eSpring force range of 1 pound initial to 4 pounds final provides consistent indexing feel\u003c\/li\u003e\n  \u003cli\u003eCompact body length of 0.79 inches suits tight-clearance assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-install spring plunger for any fixture, jig, or mechanical assembly with a pre-tapped 1\/4-20 threaded hole requiring a non-locking, hand-adjustable plunger point.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall into a clean, pre-tapped 1\/4-20 through-hole or blind hole using hand pressure on the knurled knob; use a wrench on the head flats only if thread engagement requires additional torque to seat the shoulder. Ensure the plunger bore is clear of debris before installation to prevent binding of the plunger tip. De-energize or lock out any moving machinery before servicing or replacing spring plungers in active fixtures. Verify plunger projection clearance against mating components before finalizing installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.5 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\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\u003ePlunger Length\u003c\/strong\u003e: 0.813 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Diameter Tolerance\u003c\/strong\u003e: +0.001 \/ -0.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Type\u003c\/strong\u003e: Non-Locking\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.79 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\/Shoulder\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.19 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead and Shoulder Height\u003c\/strong\u003e: 0.313 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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: KNL-1-PT-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51718126993714,"sku":"KNL-1-PT-G","price":19.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2897ef0a8a039491738213a5c779cffa.jpg?v=1788550045","url":"https:\/\/voomisupply.com\/products\/gibraltar-knl-1-pt-g-knob-handle-spring-plunger-1-4-20","provider":"Voomi Supply","version":"1.0","type":"link"}
