It features a 1\/2-13 thread size with a thread length of 0.875 inches and a body length of 1.13 inches. The plunger delivers an initial end force of 1 pound and a final end force of 10 pounds, making it suitable for light-duty spring-loaded positioning work. The knurled knob head measures 1.0 inch in diameter and 0.38 inches in height, providing a secure manual grip without the need for tools. Machinists, millwrights, and assembly technicians install this component in jigs, fixtures, and machine tool setups.\u003c\/p\u003e\u003cp\u003eThis plunger is used in applications requiring a simple, tool-free, spring-loaded locating or holding mechanism. It fits into tapped holes where a 1\/2-13 thread is specified. Typical scenarios include fixture plates, indexing tables, panel assemblies, and equipment enclosures where a repeatable manual-engagement plunger is required. The non-locking design allows the plunger to retract and extend freely without a locking mechanism, which suits applications where quick repositioning is needed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNon-locking plunger design allows free retraction and extension without a locking element\u003c\/li\u003e\n\u003cli\u003eKnurled knob head provides tool-free manual operation and a firm grip\u003c\/li\u003e\n\u003cli\u003eSpring force range of 1 pound initial to 10 pounds final end force suits light-duty positioning tasks\u003c\/li\u003e\n\u003cli\u003e1\/2-13 thread size with 0.875 inches of thread engagement length\u003c\/li\u003e\n\u003cli\u003eMaximum plunger diameter of 0.248 inches with a tight tolerance of +0.001\/-0.000 inches\u003c\/li\u003e\n\u003cli\u003eCompact body length of 1.13 inches fits in space-constrained assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for industrial fixtures, jigs, and machine assemblies requiring a 1\/2-13 threaded non-locking knob handle plunger.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by threading the plunger body into a pre-tapped 1\/2-13 hole by hand or with a spanner if needed. Ensure the mating tapped hole is clean and free of debris before installation. Disengage or de-energize any moving machinery before servicing or replacing plunger components. Do not exceed the rated end force range, as over-compression can damage the internal spring.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003ePlunger Length\u003c\/strong\u003e: 1.5 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 Projection\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1.0 inch\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\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 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: SKNL-4-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51699222249778,"sku":"SKNL-4-G","price":30.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9ec0bde6024368a3249b6d65a5b6f4e.jpg?v=1788373723","url":"https:\/\/voomisupply.com\/products\/gibraltar-sknl-4-g-knob-handle-plunger-1-2-13","provider":"Voomi Supply","version":"1.0","type":"link"}
