The steel body houses a phenolic nose and incorporates a locking element to secure the plunger in position once installed. It features a 1\/2-13 thread size with a 1-1\/4 inch thread length and delivers an initial end force of 6.6 pounds, ramping up to a final end force of 17.4 pounds. The plunger projection measures 1\/4 inch, and the plunger diameter ranges from 0.246 to 0.248 inches. Machinists, tool-and-die technicians, and assembly line maintenance personnel are the typical installers of this component.\u003c\/p\u003e\u003cp\u003eThis spring plunger is suited for use in jigs, fixtures, tooling plates, and machine assemblies where repeatable detent or positioning force is required. The locking element prevents the plunger from backing out under vibration or load cycling, making it appropriate for applications where positional retention must be maintained over repeated use. It is a standard-length plunger intended for through-hole or blind-hole threaded installations in metal or composite housings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSteel body construction provides durability in industrial environments\u003c\/li\u003e\n\u003cli\u003ePhenolic nose material reduces wear on mating surfaces\u003c\/li\u003e\n\u003cli\u003eLocking element secures the plunger body against rotation or back-out after installation\u003c\/li\u003e\n\u003cli\u003eInitial end force of 6.6 pounds and final end force of 17.4 pounds for reliable detent action\u003c\/li\u003e\n\u003cli\u003e1\/2-13 thread size with standard 1-1\/4 inch thread and body length\u003c\/li\u003e\n\u003cli\u003ePlunger projection of 1\/4 inch with a diameter range of 0.246 to 0.248 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-install threaded spring plunger for assemblies requiring a 1\/2-13 threaded hole with standard 1-1\/4 inch body length and locking element retention.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by machinists or mechanical assembly technicians using standard hex or spanner tools sized for the 1\/2-13 thread. Ensure the mating threaded hole is clean and free of debris before installation. Engage the locking element fully to prevent back-out during operation. Do not over-torque the body, as this may damage the locking element or distort the plunger bore.\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: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Plunger Diameter\u003c\/strong\u003e: 0.246 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\u003eInitial End Force\u003c\/strong\u003e: 6.6 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 17.4 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: Phenolic\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\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: SWPN-8-PT-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51719409631538,"sku":"SWPN-8-PT-G","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d544ef7920c3de3028c426cef711dcdf.jpg?v=1788559305","url":"https:\/\/voomisupply.com\/products\/gibraltar-swpn-8-pt-g-threaded-spring-plunger-1-2-13","provider":"Voomi Supply","version":"1.0","type":"link"}
