Machined from 18-8 Grade 303 stainless steel and left uncoated, this spacer provides corrosion resistance and dimensional stability in panel, enclosure, and control board installations. It measures 0.3125 inches overall length with a 0.3125 inch outside diameter and a 0.116 inch inside diameter, keeping board surfaces elevated and isolated from mounting surfaces. Electricians, panel builders, and control system technicians use this type of hardware during board installation and enclosure assembly work.\u003c\/p\u003e\n\u003cp\u003eThis spacer is suited for use in residential and commercial control panel assemblies, HVAC control boards, electrical enclosures, and industrial PCB mounting applications wherever No. 4 fastener sizing is required. The female unthreaded design accepts a No. 4 screw passed through the board and spacer body, providing consistent standoff height between the circuit board and the mounting surface. Its stainless steel construction makes it appropriate for environments with moderate moisture or corrosion exposure.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 18-8 303 stainless steel construction with uncoated finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eFemale unthreaded body accepts No. 4 screws for straightforward PCB standoff installation\u003c\/li\u003e\n  \u003cli\u003eOverall length of 0.3125 inches with tight length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 0.3125 inches and inside diameter of 0.116 inches with tolerance of 0.000 to 0.010 inches\u003c\/li\u003e\n  \u003cli\u003eConforms to fastener standard QQ-S-763\u003c\/li\u003e\n  \u003cli\u003eRound body shape for consistent seating against board and panel surfaces\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 circuit board mounting assemblies requiring a No. 4 screw, female unthreaded, round standoff with 0.3125 inch overall length and outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by electricians or panel technicians during control board assembly or enclosure build-out. Power down and de-energize the enclosure or panel completely before handling circuit boards or installing standoff hardware. Use the appropriate No. 4 fastener and confirm fit against inside diameter tolerance before final assembly. Follow applicable NEC guidelines for enclosure wiring and board mounting clearances.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel Grade 18-8 303\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\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: No. 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.3125 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\u003eOutside Diameter\u003c\/strong\u003e: 0.3125 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\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\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: S797-M07-F16-E\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51739758297394,"sku":"S797-M07-F16-E","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_f5b32b7e-91e4-4d51-8b7c-2b533f778169.jpg?v=1788818572","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s797-m07-f16-e-circuit-board-spacer-no-4","provider":"Voomi Supply","version":"1.0","type":"link"}
