It features a 1\/8-inch thread with a 2-inch thread length and a 0.5-inch maximum plunger diameter. The steel body measures 5 inches in length and 0.844 inches in diameter. Initial end force is 4 pounds, with a final end force of 31 pounds, giving this plunger a strong engagement range suited to heavier-duty positioning tasks. A locking element is included to secure the plunger in its installed position. Machinists, toolmakers, and maintenance technicians commonly install this type of plunger into threaded bores in fixtures, jigs, and machine components.\u003c\/p\u003e\n\u003cp\u003eThe HL1015 is suited for use in precision fixtures, machine tool assemblies, and production tooling where a reliable spring-loaded detent or positioning stop is required. Its long plunger configuration provides a 1.5-inch projection, making it appropriate for applications where extended reach beyond the mounting surface is necessary. The locking element allows the unit to be secured firmly after adjustment, preventing rotation or backing out under vibration or repeated cycling. This plunger is typically installed by toolmakers, machinists, or mechanical maintenance personnel in light industrial and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLong plunger style with 1.5-inch projection for extended reach applications\u003c\/li\u003e\n  \u003cli\u003eSteel body and nose construction for durability in industrial use\u003c\/li\u003e\n  \u003cli\u003eInitial end force of 4 pounds and final end force of 31 pounds for positive engagement\u003c\/li\u003e\n  \u003cli\u003eIntegrated locking element secures plunger position after installation and adjustment\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch thread size with 2-inch thread length for deep or through-bore mounting\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hex size allows standard wrench installation and removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style or replacement threaded spring plunger for industrial fixtures, jigs, and machine tool assemblies requiring a 1\/8-inch threaded bore and long-style plunger projection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires threading the plunger into a properly tapped 1\/8-inch bore using a standard wrench on the 1\/2-inch hex. Ensure the mating bore is clean and free of debris before installation. Disengage or de-energize any machinery before installing or adjusting plungers in active assemblies. Once positioned, engage the locking element to prevent the plunger from backing out during operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Length Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Length\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 0.844 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 31 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\u003eHex Size\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: Yes\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: VLIER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HL1015\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":52110425620786,"sku":"HL1015","price":107.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/131dd60f81b4c1667d812c15c548047c.jpg?v=1790076246","url":"https:\/\/voomisupply.com\/products\/vlier-hl1015-threaded-spring-plunger-1-8-thread-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
