It measures 0.625 inches overall length with a 0.25-inch outside diameter and a 0.141-inch inside diameter sized for a No. 6 screw. The unthreaded female bore accepts a No. 6 fastener to stack, offset, or mount printed circuit boards at a fixed standoff height. This spacer meets fastener standard QQ-S-763 and is well suited for electronics assemblies in HVAC controls, industrial panels, and other trade equipment requiring corrosion-resistant hardware.\u003c\/p\u003e\n\u003cp\u003eThis spacer is used wherever a precise 5\/8-inch standoff is needed between a circuit board and a mounting surface or between stacked boards. Typical applications include control board mounting in residential and light-commercial HVAC equipment, electrical enclosures, and industrial automation panels. The stainless steel construction makes it appropriate for environments with moderate moisture exposure where a zinc or steel spacer would corrode. It installs with standard No. 6 machine screws and is sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18-8 \/ 303 stainless steel construction provides corrosion resistance without a surface coating\u003c\/li\u003e\n  \u003cli\u003eFemale unthreaded bore accepts No. 6 screws for straightforward board mounting\u003c\/li\u003e\n  \u003cli\u003e0.625-inch overall length sets a consistent standoff height between board and surface\u003c\/li\u003e\n  \u003cli\u003e0.25-inch outside diameter fits standard PCB mounting hole patterns\u003c\/li\u003e\n  \u003cli\u003eMeets QQ-S-763 fastener standard for material traceability\u003c\/li\u003e\n  \u003cli\u003eUncoated finish eliminates risk of coating interference with grounded assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or maintenance-supply spacer for circuit board standoff applications requiring a female unthreaded No. 6 round spacer with a 5\/8-inch overall length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis spacer is installed by electricians, electronics technicians, and HVAC controls technicians. De-energize and lock out all power to the equipment before removing or reinstalling any circuit board or associated hardware. Use a properly sized No. 6 machine screw and avoid overtightening, which can crack the PCB substrate. Follow applicable NEC guidelines for work inside electrical enclosures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8 \/ 303\u003c\/li\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. 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.141 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\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: QQ-S-763\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\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: S537-M07-F16-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51743972753714,"sku":"S537-M07-F16-G","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_58c71d00-ff14-48e4-947b-156a9844b6af.jpg?v=1788852207","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s537-m07-f16-g-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
