It is designed to create a fixed standoff distance between a printed circuit board and a mounting surface or between stacked boards. The spacer accepts a 1\/4 inch screw, measures 0.5 inches in overall length, and has an outside diameter of 0.5 inches with an inside diameter of 0.257 inches. The zinc-plated brass construction resists corrosion and provides reliable electrical isolation in panel assemblies, control boards, and electronic enclosures. Licensed electricians, HVAC technicians, and electronics assembly professionals install this type of hardware during control board mounting and enclosure builds.\u003c\/p\u003e\n\u003cp\u003eThis spacer is suited for use in residential and commercial applications wherever circuit boards require controlled standoff spacing from a chassis or secondary board. Typical install scenarios include HVAC control panel assemblies, electrical enclosure builds, and industrial electronics mounting. The female unthreaded body allows a fastener to pass through or seat against the spacer without threading into it, making it a straightforward stack or standoff solution in tight board layouts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction meets ASTM B633, QQ-B-626 Comp 22 Type 1 fastener standards\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for added corrosion resistance in control panel environments\u003c\/li\u003e\n  \u003cli\u003eFemale unthreaded body accepts 1\/4 inch screw hardware\u003c\/li\u003e\n  \u003cli\u003eRound body shape with 0.5 inch outside diameter for consistent board spacing\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of 0.000 to 0.010 inches and length tolerance of -0.005 to 0.005 inches for precise fitment\u003c\/li\u003e\n  \u003cli\u003eSold individually, minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install spacer for circuit board assemblies requiring a 1\/4 inch screw size, 0.5 inch standoff length, and 0.5 inch outside diameter in inch-measurement systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed electricians or qualified electronics assembly technicians. De-energize all circuits and discharge any capacitors before handling control boards or installing hardware inside electrical enclosures. Use appropriately sized hand tools to seat fasteners without over-torquing, as brass hardware can be damaged by excessive force. Follow applicable NEC guidelines for enclosure and control board assembly work.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\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: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.5 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\u003eOutside Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.257 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: ASTM B633, QQ-B-626 Comp 22 Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: S1359-M01-F21-K\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51743111414066,"sku":"S1359-M01-F21-K","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_89f3155e-9b82-4d6e-8744-091e2e2f7591.jpg?v=1788842817","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s1359-m01-f21-k-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
