Machined from Grade 303 stainless steel and left bright uncoated, this spacer meets the QQ-S-763 fastener standard. It accepts a Number 4 screw, measures 1.5 inches overall length, 0.116 inches inside diameter, and 0.1875 inches outside diameter. The tight inside diameter tolerance of 0.000 to 0.010 inches and length tolerance of -0.005 to 0.005 inches make it suited for assemblies where stack height consistency matters. Electrical and electronics technicians use this hardware in control board installations across HVAC, industrial, and commercial panel applications.\u003c\/p\u003e\n\u003cp\u003eThis spacer is used wherever a Number 4 fastener is required to secure and space a circuit board from a chassis or enclosure wall. Its corrosion-resistant stainless steel construction makes it appropriate for both indoor and light-duty environments where longevity and dimensional stability are priorities. HVAC technicians, electricians, and electronics assembly professionals will find this spacer relevant for control board mounting tasks in residential and light commercial equipment. It ships individually and is packaged as a single unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 303 stainless steel construction for corrosion resistance and machinability\u003c\/li\u003e\n  \u003cli\u003eMeets QQ-S-763 fastener standard for dimensional and material compliance\u003c\/li\u003e\n  \u003cli\u003eFemale unthreaded body accepts Number 4 screw fasteners\u003c\/li\u003e\n  \u003cli\u003eOverall length of 1.5 inches with tight length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.116 inches with tolerance of 0.000 to 0.010 inches\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for assemblies requiring bare metal contact or grounding continuity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Number 4 screw fasteners in inch-measurement PCB standoff applications where a female unthreaded round spacer meeting QQ-S-763 is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by electronics technicians or licensed electricians during control board assembly or replacement. Power down and de-energize all circuits before handling or repositioning circuit boards. Use calibrated torque-limiting tools when driving Number 4 screws through this spacer to avoid deforming the unthreaded bore. Verify stack height and clearance requirements against the board layout before finalizing fastener seating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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\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: Number 4\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: 0.116 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: 0.1875 inches\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\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  \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: S373M07F16E\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51727854141746,"sku":"S373M07F16E","price":19.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_4beb91e6-bc05-4036-9106-b6bea7d44c18.jpg?v=1788683544","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s373m07f16e-round-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
