It features a 5\/16-18 threaded body with a 1 inch thread length, a steel nose, and a steel body finished in black. The plunger nose diameter measures 0.135 inches with a 3\/16 inch projection. A built-in locking element secures the plunger in place after installation, preventing loosening from vibration. Initial end force is 1.5 pounds, with a final end force of 4.5 pounds, making it suitable for light-duty detent and positioning applications. Licensed machinists, millwrights, and maintenance mechanics are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis spring plunger is used in fixtures, jigs, machine tool components, and industrial equipment where consistent detent action or positive stop positioning is required. The standard-length plunger body suits panel assemblies, slide mechanisms, and tooling plates where a 5\/16-18 tapped hole is already present or can be added. It is suited for both OEM production builds and field maintenance replacements in light industrial and manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 thread size with 1 inch thread length for secure installation in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eSteel body and steel nose for durability in industrial applications\u003c\/li\u003e\n  \u003cli\u003eBlack finish for corrosion resistance and clean appearance\u003c\/li\u003e\n  \u003cli\u003eLocking element prevents plunger from backing out due to vibration\u003c\/li\u003e\n  \u003cli\u003e1.5 pound initial end force and 4.5 pound final end force for predictable detent performance\u003c\/li\u003e\n  \u003cli\u003e5\/32 inch hex size for easy installation and removal with a standard hex key\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or OEM-style spring plunger for mechanical assemblies, fixtures, and tooling components using a standard 5\/16-18 tapped hole with a minimum thread engagement depth of 1 inch.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 5\/16-18 tapped hole and a 5\/32 inch hex key. Thread the plunger in by hand first to confirm alignment, then tighten using the hex drive to seat the locking element. De-energize or lock out any machine prior to installing or replacing spring plungers in powered equipment. Do not overtighten, as doing so may damage the locking element or distort the plunger body.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.135 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 1.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 4.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 5\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Length Type\u003c\/strong\u003e: Standard\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: JERGENS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 27326\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JERGENS","offers":[{"title":"Default Title","offer_id":52116182925618,"sku":"27326","price":16.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97cdf734beffd5dc6da28f20e40e2540.jpg?v=1790080481","url":"https:\/\/voomisupply.com\/products\/jergens-27326-threaded-spring-plunger-5-16-18-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
