It measures 1 inch overall length with a 0.25 inch outside diameter and a 0.116 inch inside diameter, sized to accept a number 4 screw. The uncoated finish leaves the base stainless steel exposed for corrosion resistance without added plating. Electricians and electronics technicians use this type of spacer to maintain consistent standoff height between a circuit board and a mounting surface, keeping the board secure and electrically isolated from the chassis or panel.\u003c\/p\u003e\u003cp\u003eThis spacer is suited for use in control board assemblies, HVAC system controllers, electrical enclosures, and similar low-voltage electronic panel applications where a compact, corrosion-resistant standoff is required. Its inch-system dimensions make it a direct fit in standard number 4 screw mounting configurations commonly found in residential and light commercial control boards and terminal assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFemale unthreaded body accepts a number 4 screw for clean, tool-based installation\u003c\/li\u003e\n\u003cli\u003e18-8 Grade 303 stainless steel construction for corrosion resistance in demanding environments\u003c\/li\u003e\n\u003cli\u003eManufactured to QQ-S-763 fastener standard for dimensional consistency\u003c\/li\u003e\n\u003cli\u003eUncoated finish  -  no plating to flake or interfere with electrical clearance\u003c\/li\u003e\n\u003cli\u003eTight length tolerance of -0.005 to 0.005 inches and ID tolerance of 0.000 to 0.010 inches for precise board standoff height\u003c\/li\u003e\n\u003cli\u003eRound body shape for uniform fitment in standard PCB mounting hole patterns\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 assemblies using number 4 screw mounting hardware in inch-system configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis spacer is installed by electricians or electronics technicians during control board assembly or replacement work. Always de-energize the panel or control system and verify zero voltage before handling circuit boards or fasteners. Use a screwdriver or hex driver matched to the number 4 screw head to avoid stripping the fastener. Follow applicable NEC guidelines for electrical enclosure work when installing or servicing control assemblies.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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 inch\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: 0.25 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\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8 Grade 303\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: 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\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: S561-M07-F16-E\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51744427049266,"sku":"S561-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_ffa27fa2-0485-470b-bf37-ab8aaba78b25.jpg?v=1788856378","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s561-m07-f16-e-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
