It provides a rigid, corrosion-resistant standoff between a circuit board and a mounting surface, maintaining a fixed separation while allowing a 1\/4-inch screw to pass through its 0.257-inch inside diameter bore. The spacer measures 1.5 inches in overall length with a 0.5-inch outside diameter and carries no surface coating, leaving the base stainless finish exposed. It is used in control panel assemblies, electronic enclosures, and equipment where board-to-surface clearance must be held to a precise tolerance. Electricians, controls technicians, and OEM assembly personnel are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis spacer fits applications requiring a 1\/4-inch thread size clearance hole in inch-measurement systems. Its 18-8 Grade 303 stainless steel construction makes it well-suited for indoor control panels, HVAC equipment boards, and light industrial enclosures where mild corrosion resistance is needed. The uncoated finish is appropriate where a bare stainless surface meets electrical or structural requirements. It conforms to fastener standard QQ-S-763, which governs corrosion-resistant steel bars and wire used in fastener fabrication.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale unthreaded bore accepts 1\/4-inch screws with a 0.257-inch inside diameter clearance\u003c\/li\u003e\n  \u003cli\u003e18-8 Grade 303 stainless steel construction per QQ-S-763 for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e1.5-inch overall length with tight length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e0.5-inch outside diameter with inside diameter tolerance of 0.000 to 0.010 inches\u003c\/li\u003e\n  \u003cli\u003eRound body shape, uncoated finish, inch measurement system\u003c\/li\u003e\n  \u003cli\u003eSold individually — package 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 service spacer for circuit board mounting assemblies requiring a 1\/4-inch screw clearance, 1.5-inch standoff height, and 0.5-inch outside diameter in inch-dimensioned hardware configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by electricians or controls technicians during panel assembly or board replacement. Always de-energize the equipment and follow applicable NEC lockout\/tagout procedures before accessing any control board or enclosure. Confirm the mating screw thread size and board hole pattern before installation to avoid damage to the spacer bore or mounting surface. Do not over-torque the fastener, as the unthreaded bore provides no thread engagement and relies on the clamping force of the screw and mating hardware.\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\u003eFastener Standard\u003c\/strong\u003e: QQ-S-763\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Thread Size\u003c\/strong\u003e: 1\/4 inch\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: 0.257 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\u003eOutside Diameter\u003c\/strong\u003e: 0.5 inches\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\u003eFinish\u003c\/strong\u003e: Uncoated\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: S1423-M07-F16-K\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51746400600370,"sku":"S1423-M07-F16-K","price":18.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64ed36ec3a1c33caaf172ec4e8fe95b6_0cad40d0-ca5c-4ce4-8edf-1639f8bb380d.jpg?v=1788869582","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s1423-m07-f16-k-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
