Molded from Nylon Grade 101 and left uncoated, this spacer accepts a No. 6 screw through its 0.141 inch inside diameter bore. The overall length is 0.25 inches, with an outside diameter of 0.25 inches. Manufactured to MIL-P-17091B, it provides consistent dimensional tolerances suitable for production and repair applications in electronics assemblies found across HVAC control boards, electrical panels, and related trade equipment.\u003c\/p\u003e\u003cp\u003eThis spacer is used wherever a No. 6 fastener is employed to secure a printed circuit board at a fixed standoff height of 0.25 inches. Common applications include residential and commercial HVAC control board assemblies, electrical enclosure PCB mounting, and general electronic equipment repair. The nylon construction makes it appropriate for environments where electrical isolation between the board and chassis is required. It is sold individually but carries a minimum order quantity of 100 units, making it suited for shop stock and production use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFemale unthreaded bore accepts No. 6 screws for straightforward PCB standoff mounting\u003c\/li\u003e\n\u003cli\u003eNylon Grade 101 construction provides electrical isolation and corrosion resistance\u003c\/li\u003e\n\u003cli\u003eMeets MIL-P-17091B fastener standard for dimensional and material consistency\u003c\/li\u003e\n\u003cli\u003eUncoated bright finish with inside diameter tolerance of 0.000 to 0.010 inches\u003c\/li\u003e\n\u003cli\u003eCompact 0.25 inch OAL and 0.25 inch OD fit tight board clearances\u003c\/li\u003e\n\u003cli\u003eLength tolerance held to -0.005 to 0.005 inches for repeatable stack-up control\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard No. 6 screw circuit board spacer for PCB mounting applications requiring a 0.25 inch standoff height and female unthreaded body in an inch-measurement fastener system.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electricians, electronics technicians, or HVAC service professionals during control board replacement or assembly work. De-energize all circuits and discharge any capacitors before handling circuit boards or fasteners. Use a properly sized No. 6 screw and avoid over-torquing, which can crack the nylon body. Verify standoff height requirements against the board manufacturer's documentation before selecting spacer length.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nylon Grade 101\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 101\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: MIL-P-17091B\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: 0.25 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: 0.141 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\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\u003eWeight\u003c\/strong\u003e: 1 pound\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: S513M17F16G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51746525446450,"sku":"S513M17F16G","price":1021.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd0682321cdb19d420e78b064b65a3dc.jpg?v=1788871021","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s513m17f16g-round-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
