It measures 3\/16 inches (0.1875 inches) overall length, with a 0.194-inch inside diameter and a 0.5-inch outside diameter. Designed for use with number 10 screws, this spacer creates a fixed standoff gap between a printed circuit board and a mounting surface or between stacked boards. The uncoated finish is standard for applications where bare aluminum is acceptable. It is installed by electronics technicians and field service professionals who require precise board-to-surface clearance in control assemblies and enclosures.\u003c\/p\u003e\u003cp\u003eThis spacer is suited for use in residential and commercial control boards, HVAC equipment electronics, panel assemblies, and industrial enclosures where a compact, lightweight standoff is needed. The round body and female unthreaded bore accept a number 10 screw passed through from the opposite side, making it a simple, tool-minimal component to install during board mounting or replacement. Its small overall length makes it appropriate for tight enclosure layouts where vertical clearance is limited.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFemale unthreaded bore sized for number 10 screw applications\u003c\/li\u003e\n\u003cli\u003e0.1875-inch overall length with a tight length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003e0.194-inch inside diameter with an inside diameter tolerance of 0.000 to 0.010 inches\u003c\/li\u003e\n\u003cli\u003e0.5-inch outside diameter, round body profile\u003c\/li\u003e\n\u003cli\u003eAluminum grade T-3 construction per QQ-A-225A Comp 2 fastener standard\u003c\/li\u003e\n\u003cli\u003eUncoated finish; no surface treatment applied\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation spacer for circuit board mounting applications that require a number 10 screw, female unthreaded aluminum standoff with a 0.5-inch outside diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation does not require specialized tools beyond a standard screwdriver or nut driver sized for the number 10 fastener. Ensure the mating screw length accounts for both the spacer length and the board thickness to avoid bottoming out or insufficient thread engagement. Power down and de-energize any control board assembly fully before handling circuit boards or fasteners. Follow applicable facility or equipment lockout procedures prior to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: T-3\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\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\u003eScrew Size\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.1875 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\u003eInside Diameter\u003c\/strong\u003e: 0.194 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\u003eOutside Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: S1339-M04-F16-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51743357174066,"sku":"S1339-M04-F16-I","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_c097b328-1945-494b-a6c7-fef9b1c664dd.jpg?v=1788846104","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s1339-m04-f16-i-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
