Machined from 18-8 grade 303 stainless steel and left uncoated, this spacer provides corrosion resistance and dimensional stability in demanding service environments. It accepts a number 8 screw, measures 1.5 inches overall length, 0.171 inches inside diameter, and 0.375 inches outside diameter. Electricians, control panel builders, and electronics technicians use this fastener hardware when assembling or servicing board-level components in HVAC controls, industrial panels, and related equipment.\u003c\/p\u003e\u003cp\u003eThis spacer is suited for applications where a precise standoff distance is needed between a circuit board and a mounting surface or between stacked boards. Its female unthreaded bore and round body shape make it appropriate for use in residential and light commercial control enclosures, HVAC control boards, relay panels, and similar assemblies requiring a clean, stable mounting solution. The stainless steel construction meets the QQ-S-763 fastener standard, making it appropriate for environments where mild corrosion resistance is a requirement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e18-8 grade 303 stainless steel construction meets QQ-S-763 fastener standard\u003c\/li\u003e\n\u003cli\u003eFemale unthreaded bore accepts a number 8 screw\u003c\/li\u003e\n\u003cli\u003e1.5 inches overall length with a tight length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003e0.171 inches inside diameter with a tolerance of 0.000 to 0.010 inches\u003c\/li\u003e\n\u003cli\u003e0.375 inches outside diameter in a round body profile\u003c\/li\u003e\n\u003cli\u003eUncoated finish maintains dimensional accuracy and avoids coating buildup in tight clearances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service spacer for circuit board mounting applications requiring a number 8 screw, 1.5 inches overall length, and 0.375 inches outside diameter in inch-measurement systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed electrician or qualified control panel technician. Always de-energize the equipment and follow lockout\/tagout procedures before servicing any control board or panel assembly. Use the correct number 8 fastener to avoid bore damage, and verify the spacer length provides adequate clearance for the specific board and enclosure design. Refer to applicable NEC requirements for control panel assembly and wiring practices.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel 18-8, Grade 303\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: QQ-S-763\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: Number 8\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\u003eOverall Length\u003c\/strong\u003e: 1.5 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\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\u003eOutside Diameter\u003c\/strong\u003e: 0.375 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\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: S1143-M07-F16-H\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51755781521714,"sku":"S1143-M07-F16-H","price":18.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_f8abf1e7-c5fa-44a5-aab4-e292b0288ada.jpg?v=1788959613","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s1143-m07-f16-h-board-spacer-8-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
