It accepts a 1\/4 inch screw, measures 3\/16 inches (0.1875 inches) overall length, and carries an inside diameter of 0.257 inches with an outside diameter of 0.5 inches. The uncoated finish preserves the natural corrosion resistance of the stainless alloy. Electricians, panel builders, and control board technicians use this type of spacer to maintain precise standoff clearance between a circuit board and its mounting surface, preventing shorts and managing airflow across board components.\u003c\/p\u003e\n\u003cp\u003eThis spacer is suited for use in control panel assemblies, HVAC control board mounting applications, electrical enclosures, and light commercial equipment where a reliable stainless standoff is required. Its compact 3\/16 inch overall length makes it appropriate for tight board-to-chassis clearances. The inch-system dimensions and 1\/4 inch thread compatibility align with standard North American fastener sizing commonly found in residential and light commercial equipment builds and service replacements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18-8 and 303 grade stainless steel construction meets QQ-S-763 fastener standard\u003c\/li\u003e\n  \u003cli\u003eFemale unthreaded body accepts 1\/4 inch screw for straightforward mounting\u003c\/li\u003e\n  \u003cli\u003eOverall length of 3\/16 inches (0.1875 inches) with a tight length tolerance of -0.005 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.257 inches with an ID tolerance of 0.000 to 0.010 inches\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 0.5 inches for consistent standoff footprint\u003c\/li\u003e\n  \u003cli\u003eUncoated finish retains stainless corrosion resistance without added coating thickness\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 applications requiring a 1\/4 inch screw, 3\/16 inch overall length, and 0.5 inch outside diameter in stainless steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by electricians or control board technicians during panel assembly or board replacement service. De-energize all circuits and follow applicable NEC guidelines before handling any control board or panel component. Use the correct 1\/4 inch fastener to avoid damaging the unthreaded female bore. Verify overall length and inside diameter clearances against the board and chassis specifications before final assembly.\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: 18-8 and 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\u003eScrew Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3\/16 inches (0.1875 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\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: S1339-M07-F16-K\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51731931988274,"sku":"S1339-M07-F16-K","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6ee849215c9586f19cee4af9d6749c03.jpg?v=1788736821","url":"https:\/\/voomisupply.com\/products\/electro-hardware-s1339-m07-f16-k-circuit-board-spacer","provider":"Voomi Supply","version":"1.0","type":"link"}
