It delivers an initial end force of 6.6 pounds and a final end force of 17.4 pounds, making it suitable for positioning, indexing, and light-duty detent applications in mechanical assemblies. The plunger diameter measures 0.248 inches with a 1\/4 inch projection. Both the body and nose are constructed from steel with a black finish. This type of component is typically installed by machinists, tool and die technicians, or maintenance mechanics working on jigs, fixtures, and machine tooling.\u003c\/p\u003e\n\u003cp\u003eThis spring plunger is used in industrial and mechanical settings where a threaded, spring-loaded retention or positioning element is required. Common applications include fixture plates, tooling blocks, workholding devices, and assembly jigs where controlled plunger engagement and release are needed. The 1\/2-13 thread allows installation into standard tapped holes without special tooling. The no-locking-element design suits applications where the plunger must be field-removable or periodically serviced without staking or adhesive retention.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 thread size with 1-1\/4 inch thread length for standard tapped-hole installation\u003c\/li\u003e\n  \u003cli\u003e6.6 pound initial end force and 17.4 pound final end force for reliable detent and positioning performance\u003c\/li\u003e\n  \u003cli\u003eSteel body and steel nose construction with black finish for durability\u003c\/li\u003e\n  \u003cli\u003e0.248 inch plunger diameter with 1\/4 inch projection\u003c\/li\u003e\n  \u003cli\u003eNo locking element — field-removable without staking or thread-locking compound\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch hex size for installation with a standard hex wrench\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style threaded spring plunger for standard 1\/2-13 tapped holes in industrial fixtures, tooling plates, and mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by threading the plunger into a clean, properly tapped 1\/2-13 hole using a 1\/4 inch hex wrench. Ensure the mating bore is free of debris and correctly sized before installation to avoid thread damage. De-energize or lock out any machine or assembly before installing or removing spring plungers to prevent unintended movement. Do not over-torque, as this may damage the body or distort thread engagement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.248 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\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: 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: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Length Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance\u003c\/strong\u003e: +0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: GIBRALTAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 57081XG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51701565391154,"sku":"57081XG","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/391dd9793a2e1dd0618cf0e8fcc4ffcd.jpg?v=1788401612","url":"https:\/\/voomisupply.com\/products\/gibraltar-57081xg-threaded-spring-plunger-1-2-13-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
