It measures 0.25 inches in overall length and 0.25 inches in outside diameter, with an inside diameter of 0.116 inches sized to accept a No. 4 screw. The uncoated finish leaves the stainless bare, relying on the corrosion resistance of the 18-8 alloy rather than a secondary coating. Electronics technicians and field service pros use these spacers to maintain consistent standoff clearance between a printed circuit board and its mounting surface.\u003c\/p\u003e\u003cp\u003eThis spacer is appropriate for use in control board assemblies found across residential and light commercial equipment, including HVAC control boards, motor drive modules, and similar low-voltage electronic enclosures where a No. 4 fastener pattern is specified. The round body profile and tight length tolerance of plus or minus 0.005 inches make it well suited to applications where consistent board height is required across multiple mounting points.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFemale unthreaded round body accepts No. 4 screws\u003c\/li\u003e\n\u003cli\u003eOverall length of 0.25 inches with length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003eOutside diameter of 0.25 inches; inside diameter of 0.116 inches with tolerance of 0.000 to 0.010 inches\u003c\/li\u003e\n\u003cli\u003e18-8 303 stainless steel construction meets QQ-S-763 fastener standard\u003c\/li\u003e\n\u003cli\u003eUncoated finish  -  no secondary plating or coating applied\u003c\/li\u003e\n\u003cli\u003eInch measurement system; sold individually\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard No. 4 screw circuit board spacer for use in electronic control board mounting applications where a 0.25-inch standoff height and 0.25-inch outside diameter are required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by electronics technicians or field service personnel during control board replacement or assembly. De-energize all affected circuits and discharge any capacitors before handling circuit boards or fasteners. Use appropriately sized No. 4 hardware and avoid over-tightening, which can crack board substrate or distort the spacer. Follow applicable equipment manufacturer torque guidance and relevant electrical codes when reassembling control enclosures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Female Unthreaded Round Spacer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: No. 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.25 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: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.116 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: Stainless Steel 18-8 303\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\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: S513-M07-F16-E\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51739974238514,"sku":"S513-M07-F16-E","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0789934acebacea9d81fd0c7b875d5fa.jpg?v=1788820923","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s513-m07-f16-e-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
