It accepts a No. 8 screw and provides a fixed standoff between a PCB and a mounting surface or between stacked boards. The spacer measures 0.75 inches overall length, 0.3125 inches outside diameter, and 0.171 inches inside diameter with an inside diameter tolerance of 0.000 to 0.010 inches and a length tolerance of -0.005 to 0.005 inches. The uncoated finish leaves the aluminum bare, which is appropriate where added coatings would affect clearance or conductivity requirements.\u003c\/p\u003e\n\u003cp\u003eThis spacer is suited for PCB mounting applications in HVAC control boards, electrical enclosures, pool equipment electronics, and other trade equipment where a lightweight, corrosion-resistant aluminum standoff is needed. It is commonly installed during control board replacement or panel assembly in both residential and light commercial equipment. The No. 8 screw compatibility makes it a standard fit for widely used fastener patterns on control assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale unthreaded body accepts No. 8 screws for straightforward board-to-chassis mounting\u003c\/li\u003e\n  \u003cli\u003eAluminum grade T-3 construction per QQ-A-225A Comp 2 for lightweight, corrosion-resistant performance\u003c\/li\u003e\n  \u003cli\u003e0.75 inches overall length provides consistent board standoff height\u003c\/li\u003e\n  \u003cli\u003e0.3125 inches OD and 0.171 inches ID with tight tolerances for precise fit\u003c\/li\u003e\n  \u003cli\u003eUncoated finish maintains dimensional accuracy where surface treatments are not required\u003c\/li\u003e\n  \u003cli\u003eRound body shape for standard spacer footprint on control boards and enclosure panels\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or stock spacer for circuit board mounting applications requiring a No. 8 screw, female unthreaded aluminum standoff with 0.75 inches overall length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis spacer is typically installed by electricians, HVAC technicians, or electronics service technicians during control board mounting or panel assembly. Always de-energize the equipment and follow lockout\/tagout procedures before working on any control board or electrical enclosure. Use the correct No. 8 fastener and avoid over-torquing, which can crack the PCB or deform the spacer. Verify spacer height provides adequate clearance between the board and the mounting surface before final assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Female Unthreaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: No. 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.75 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\u003eOutside Diameter\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.171 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\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\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\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: S825-MO4-F16-H\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51741384245554,"sku":"S825-MO4-F16-H","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_1dba774d-4953-4e92-9815-89822a3a1e60.jpg?v=1788831139","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s825-mo4-f16-h-circuit-board-spacer-aluminum","provider":"Voomi Supply","version":"1.0","type":"link"}
