It measures 0.5 inches overall length with an inside diameter of 0.219 inches and an outside diameter of 0.375 inches, sized for a No. 12 screw. The uncoated finish leaves the aluminum bare for applications where coating is not required. Electronics technicians and electrical trades use this spacer to maintain precise standoff distance between a printed circuit board and a mounting surface, protecting board components from contact or vibration damage.\u003c\/p\u003e\n\u003cp\u003eThis spacer is suited for use in control boards, PCB assemblies, and electronic enclosures found in HVAC control panels, electrical distribution equipment, industrial controls, and similar trade applications. The female unthreaded bore accepts a No. 12 fastener passed through the body, making it appropriate for through-bolt or stacking configurations. Its compact outside diameter of 0.375 inches fits standard PCB mounting hole layouts without interference. Installation is typically performed by electronic technicians or licensed electricians during board assembly or field service of control enclosures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale unthreaded round body sized for No. 12 screw clearance\u003c\/li\u003e\n  \u003cli\u003e0.5 inches overall length with tight length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.219 inches with tolerance of 0.000 to 0.010 inches\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 0.375 inches for standard PCB mounting footprints\u003c\/li\u003e\n  \u003cli\u003eAluminum grade T-3, QQ-A-225A Comp 2, uncoated finish\u003c\/li\u003e\n  \u003cli\u003eInch measurement system; sold individually with minimum order quantity of 5\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation spacer for printed circuit board assemblies requiring a No. 12 screw, round female unthreaded aluminum standoff with 0.5 inches overall length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDe-energize and lockout the equipment before servicing any control board or electronic enclosure. Align the spacer body over the PCB mounting hole before inserting the fastener to avoid misalignment that could crack the board. Use a torque-controlled driver appropriate for the No. 12 fastener to avoid stripping the mating threads in the standoff stack. Installation should follow applicable NEC guidelines for control wiring and enclosure work.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.219 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: 0.000 to 0.010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: No. 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Female Unthreaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum, Grade T-3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: QQ-A-225A Comp 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: ELECTRO HARDWARE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: S1079-M04-F16-J\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51740521398578,"sku":"S1079-M04-F16-J","price":18.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/86d5a4ddce7c72e9bd694a51ee19d139.jpg?v=1788825638","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s1079-m04-f16-j-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
