It measures 0.75 inches overall length with an outside diameter of 0.375 inches and an inside diameter of 0.194 inches, sized to accept a number 10 screw. This spacer is used to create a fixed standoff gap between a circuit board and a mounting surface, preventing electrical shorts and providing mechanical support. It is installed by electronics technicians, HVAC controls specialists, and electricians working on control board assemblies in commercial and residential equipment.\u003c\/p\u003e\n\u003cp\u003eThis spacer fits typical control board mounting applications where a number 10 fastener is used. The female unthreaded design accepts a screw passed through from the board side, holding the board at a consistent standoff height. Common applications include HVAC control boards, industrial enclosures, motor control panels, and other equipment requiring precise board-to-chassis clearance. Its compact outside diameter of 0.375 inches keeps it well-suited for dense board layouts where spacing is limited.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 2 steel construction meets ASTM B633 and QQ-S-633 Type 1 standards for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides protection against oxidation in typical enclosure environments\u003c\/li\u003e\n  \u003cli\u003eFemale unthreaded bore accepts a number 10 screw for straightforward board mounting\u003c\/li\u003e\n  \u003cli\u003eTight length tolerance of -0.005 to 0.005 inches ensures consistent standoff height across multiple mounting points\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of 0.000 to 0.010 inches maintains proper screw fit without play\u003c\/li\u003e\n  \u003cli\u003eRound body shape with 0.375 inch OD fits standard PCB mounting hole patterns\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in circuit board assemblies that use number 10 fasteners and require a 0.75 inch standoff with a 0.375 inch outside diameter.

Position the spacer between the board and the mounting surface, then pass a number 10 screw through the board and spacer bore. Do not overtighten fasteners, as the unthreaded bore does not engage threads and excess torque may deform the spacer or damage the board. Follow applicable electrical codes and equipment manufacturer guidelines for control board service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel, Grade 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.75 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\u003eInside Diameter\u003c\/strong\u003e: 0.194 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 Tolerance\u003c\/strong\u003e: 0.000 to 0.010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: Number 10\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standards\u003c\/strong\u003e: ASTM B633, QQ-S-633 Type 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: S1095-M10-F21-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51743246057778,"sku":"S1095-M10-F21-I","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_2f217681-ab34-4775-98c7-060bf915a5c7.jpg?v=1788844468","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s1095-m10-f21-i-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
