It features a 1\/2-13 thread with a 0.875-inch thread length and a 1.13-inch body length. The knurled knob head provides a secure hand grip for frequent adjustment without tools. Spring force ranges from 1 pound initial end force to 10 pounds final end force, making it suitable for light-duty hold and locate functions. The maximum plunger diameter is 0.248 inches with a plunger projection of 0.25 inches. Installed by machinists, maintenance technicians, and mechanical assemblers in production fixtures, jigs, and equipment panels.\u003c\/p\u003e\n\u003cp\u003eThis plunger is used in applications requiring repeatable manual positioning, such as machine tool fixtures, industrial enclosures, and equipment adjustment mechanisms. The non-locking plunger design allows the spring-loaded tip to retract and re-engage under hand pressure. The knurled knob head suits installations where the plunger must be adjusted frequently during operation or setup. Typical environments include light manufacturing, automation equipment, and mechanical assemblies where a threaded body can be installed into a tapped hole.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNon-locking spring-loaded plunger for quick manual indexing and positioning\u003c\/li\u003e\n  \u003cli\u003eKnurled knob head allows tool-free adjustment with positive hand grip\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 thread with 0.875-inch thread length for standard tapped-hole installation\u003c\/li\u003e\n  \u003cli\u003eSpring end force range of 1 pound initial to 10 pounds final for light-duty hold applications\u003c\/li\u003e\n  \u003cli\u003eMaximum plunger diameter of 0.248 inches with a 0.25-inch plunger projection\u003c\/li\u003e\n  \u003cli\u003eLocking element included for secure body retention once positioned in the mounting hole\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-thread replacement or new-install knob handle plunger for equipment with a 1\/2-13 tapped mounting hole requiring a non-locking spring plunger with a knurled knob actuator.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by threading the plunger body into a properly tapped 1\/2-13 hole using hand pressure or a wrench on the body, not on the knob head. Verify the mating hole depth and thread engagement before fully seating the component. Engage the locking element per the assembly design to prevent the body from backing out under vibration. No special tools or trade licensing are required, though standard machining and assembly practices apply.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 1.13 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\/Shoulder\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.38 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead and Shoulder Height\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.248 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 Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.25 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: 10 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Type\u003c\/strong\u003e: Non-Locking\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKnob Style\u003c\/strong\u003e: Knurled\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: Yes\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\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-4-PT-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51709416538418,"sku":"KNL-4-PT-G","price":21.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cc1e614d15b0f93d4198b93fa497774e.jpg?v=1788456129","url":"https:\/\/voomisupply.com\/products\/gibraltar-knl-4-pt-g-knob-handle-plunger-1-2-13","provider":"Voomi Supply","version":"1.0","type":"link"}
