Built from Nylon Grade 101 and supplied uncoated, this spacer meets MIL-P-17091B fastener standards. It measures 1.25 inches overall length (OAL), with a 0.089 inch inside diameter and a 0.1875 inch (3\/16 inch) outside diameter, sized for number 2 screw applications. Electronics assemblers, HVAC controls technicians, and electrical panel builders install this type of spacer during board mounting operations where controlled standoff height is required.\u003c\/p\u003e\n\u003cp\u003eThis spacer is appropriate for use in control board assemblies found in residential and light commercial HVAC equipment, electrical enclosures, and industrial PCB installations. The round body profile and female unthreaded bore allow a number 2 fastener to pass through cleanly, creating a fixed standoff stack between the board and chassis. Its nylon construction makes it suitable for applications where electrical isolation between the board and mounting hardware is needed. This SKU is sold individually, with a minimum order quantity of 100 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\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 consistent dimensional quality\u003c\/li\u003e\n  \u003cli\u003eFemale unthreaded bore accepts number 2 screws without thread engagement\u003c\/li\u003e\n  \u003cli\u003e1.25 inch OAL with tight length tolerance of -0.005 to 0.005 inches for precise standoff height\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of 0.000 to 0.010 inches over the 0.089 inch nominal ID\u003c\/li\u003e\n  \u003cli\u003eUncoated bright finish — no plating to crack, chip, or add unintended conductivity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation spacer for number 2 screw circuit board mounting applications in control boards, PCB assemblies, and electrical enclosures requiring a 1.25 inch standoff height.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCircuit board spacers of this type are installed by electronics assemblers or controls technicians during board mounting procedures. Always power down and de-energize the equipment before handling circuit boards or installing spacers. Verify screw size and standoff height requirements against the board drawing before selecting quantity. Nylon spacers should not be overtightened, as the material can crack or deform under excessive clamp load.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (ID)\u003c\/strong\u003e: 0.089 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter (OD)\u003c\/strong\u003e: 0.1875 inches (3\/16 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\u003eThread Size\u003c\/strong\u003e: Number 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Female Unthreaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nylon Grade 101\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated (Bright)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: MIL-P-17091B\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: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100 units\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: S357M17F16C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51730812338482,"sku":"S357M17F16C","price":1052.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_cffb9c8a-c09c-4a62-889a-81ce7ba2258e.jpg?v=1788723248","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s357m17f16c-round-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
