Machined from Grade 303 stainless steel and left uncoated with a bright finish, this spacer meets the QQ-S-763 fastener standard. It accepts a No. 4 screw, measures 0.75 inches overall length, and has an inside diameter of 0.116 inches with an outside diameter of 0.1875 inches. Licensed electricians, electronics technicians, and board-level service professionals use this type of fastener hardware when assembling or servicing control boards in HVAC equipment, industrial panels, and similar enclosures.\u003c\/p\u003e\u003cp\u003eThis spacer is suited for applications requiring a compact, corrosion-resistant standoff between a circuit board and a chassis or mounting plate. The stainless steel construction makes it appropriate for environments with exposure to moisture or mild chemicals. It is used in both original-equipment manufacturing and field-service scenarios where a No. 4 screw pattern is specified. The female unthreaded design accepts a No. 4 fastener passed through from the board side, allowing the screw to set the clamping load directly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 303 stainless steel construction meeting QQ-S-763 fastener standard\u003c\/li\u003e\n\u003cli\u003eFemale unthreaded body accepts No. 4 screw\u003c\/li\u003e\n\u003cli\u003eOverall length of 0.75 inches with a length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003eInside diameter of 0.116 inches with a tolerance of 0.000 to 0.010 inches\u003c\/li\u003e\n\u003cli\u003eOutside diameter of 0.1875 inches in a round body profile\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for electrically conductive grounding contact\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style circuit board spacer for applications requiring a No. 4 screw, round body profile, and 0.75-inch standoff height in stainless steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed electrician or electronics technician. De-energize and lock out all power to the control board assembly before handling or replacing spacers. Use a calibrated torque driver appropriate for No. 4 fasteners to avoid over-stressing the board substrate. Follow applicable NEC guidelines and equipment manufacturer instructions when reassembling control board enclosures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.75 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\u003eOutside Diameter\u003c\/strong\u003e: 0.1875 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\u003eScrew Size\u003c\/strong\u003e: No. 4\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\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 303\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ 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\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: S325M07F16E\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51746958868786,"sku":"S325M07F16E","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_bd0d2e21-7f57-436c-81e9-9cf461962a93.jpg?v=1788874924","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s325m07f16e-round-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
