It is designed to create a fixed standoff gap between a printed circuit board and a mounting surface or second board layer. The spacer measures 0.125 inches overall length, 0.3125 inches outside diameter, and 0.171 inches inside diameter, accepting a number 8 screw. The uncoated aluminum construction keeps the part lightweight and thermally stable. Electrical and controls technicians install these spacers during PCB mounting and panel assembly work in HVAC controls, electrical enclosures, and similar low-voltage equipment.\u003c\/p\u003e\u003cp\u003eThis spacer is suited for residential and light commercial applications where PCBs require secure, consistent standoff spacing. Typical uses include control board mounting in HVAC equipment, terminal strip assemblies, and general electronics panel fabrication. Its compact 1\/8-inch length makes it appropriate for tight board-to-surface clearances. The female unthreaded bore accommodates a number 8 fastener passed through the board and spacer into a threaded receiver below. Technicians working on control panel builds, service replacements, and OEM-style repairs will find this spacer a standard fit for low-profile PCB mounting configurations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFemale unthreaded bore sized for number 8 screw fasteners\u003c\/li\u003e\n\u003cli\u003e0.125 inches overall length for low-profile standoff applications\u003c\/li\u003e\n\u003cli\u003e0.3125 inches outside diameter with 0.171 inches inside diameter\u003c\/li\u003e\n\u003cli\u003eAluminum grade T-3 construction per QQ-A-225A Comp 2 specification\u003c\/li\u003e\n\u003cli\u003eUncoated finish  -  no plating to interfere with fit or electrical grounding paths\u003c\/li\u003e\n\u003cli\u003eInside diameter tolerance of 0.000 to 0.010 inches and length tolerance of -0.005 to 0.005 inches for consistent fit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-install spacer for circuit board mounting applications requiring a number 8 screw, 1\/8-inch standoff height, and 5\/16-inch outside diameter in aluminum construction.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electricians, controls technicians, and electronics assembly personnel. De-energize all circuits and discharge any stored capacitance before handling PCBs or mounting hardware. Use appropriately sized number 8 fasteners and avoid overtightening, which can crack board mounting holes or deform the aluminum spacer. Installations inside electrical enclosures should conform to applicable NEC guidelines for control panel assembly.\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\u003eScrew Size\u003c\/strong\u003e: Number 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.125 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\u003eLength Tolerance\u003c\/strong\u003e: -0.005 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Round\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\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: S785-MO4-F16-H\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51740042297650,"sku":"S785-MO4-F16-H","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c2ebe59c336064e63e84bc1d4aafe8f1.jpg?v=1788821765","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s785-mo4-f16-h-round-board-spacer-aluminum","provider":"Voomi Supply","version":"1.0","type":"link"}
