The steel body and steel nose deliver reliable wear resistance in production and maintenance environments. Thread size is 1\/8 with a thread length of 2 inches, allowing secure installation into standard threaded housings. The plunger projects 1 inch and delivers an initial end force of 4 pounds and a final end force of 22 pounds, making it suitable for applications requiring a firm, repeatable detent. A locking element is included to prevent the plunger from backing out under vibration or repeated cycling. Installation is typically performed by machine builders, tool-and-die technicians, or maintenance mechanics.\u003c\/p\u003e\n\u003cp\u003eThe HL1000 is used in fixtures, jigs, tooling plates, and mechanical assemblies where controlled plunger engagement is required. The long plunger design with a 7-inch total plunger length and 5-inch body length suits applications where extended reach or deep-housing mounting is needed. This part is sold individually (package quantity of 1) and is appropriate for both OEM assembly and field replacement in light industrial and precision manufacturing settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/8 thread size with 2-inch thread length for secure housing installation\u003c\/li\u003e\n  \u003cli\u003e1-inch plunger projection with 4-pound initial and 22-pound final end force\u003c\/li\u003e\n  \u003cli\u003eSteel body and steel nose for durability in industrial environments\u003c\/li\u003e\n  \u003cli\u003eLocking element prevents backing out under vibration or repeated use\u003c\/li\u003e\n  \u003cli\u003eLong plunger configuration with 7-inch total plunger length\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch hex size for 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 replacement or direct-install component for standard 1\/8-threaded housings in industrial fixtures, jigs, and mechanical assemblies requiring a long-body spring plunger.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by threading the HL1000 into a pre-tapped 1\/8 housing using a 1\/2-inch wrench on the hex body. Disengage or de-energize any machinery before servicing components in the assembly. The locking element should be engaged after torquing to the assembler's specified value to prevent loosening. Do not exceed the rated final end force load to avoid premature spring fatigue.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTotal Plunger Length\u003c\/strong\u003e: 7 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\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\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: 22 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\u003eLocking Element\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Length Type\u003c\/strong\u003e: Long\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: HL1000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51965439541554,"sku":"HL1000","price":96.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/539a7093b2b6c013ea6e59b7ade061e3.jpg?v=1789949767","url":"https:\/\/voomisupply.com\/products\/vlier-hl1000-threaded-spring-plunger-1-8-thread","provider":"Voomi Supply","version":"1.0","type":"link"}
