Machined from 303 stainless steel with a plain (bright\/uncoated) finish, this standoff measures 5\/16 inches overall length with a 3\/16-inch width across flats. The fully threaded female interior accepts a 4-40 thread with a 5\/16-inch thread depth, providing reliable thread engagement in compact board-level assemblies. Electronics technicians, electrical contractors, and panel builders rely on standoffs like this to maintain proper clearance and grounding separation in control panels and printed circuit board installations.\u003c\/p\u003e\u003cp\u003eThis standoff is suited for use in residential and commercial electrical enclosures, HVAC control boards, industrial panel assemblies, and any application requiring a small-profile, corrosion-resistant PCB spacer. The hex body allows for tool-assisted installation and removal in tight spaces. Its inch-system dimensions align with standard 4-40 fastener hardware commonly found in domestic control board and electronics assembly work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFemale hex body accepts 4-40 threaded fasteners for secure board-to-board or board-to-panel mounting\u003c\/li\u003e\n\u003cli\u003eFully threaded interior with 5\/16-inch thread depth for maximum thread engagement in a compact form factor\u003c\/li\u003e\n\u003cli\u003e303 stainless steel construction provides corrosion resistance and long service life in humid or outdoor-rated enclosures\u003c\/li\u003e\n\u003cli\u003ePlain (bright\/uncoated) finish meets QQ-S-763 fastener standards\u003c\/li\u003e\n\u003cli\u003eHex body shape allows wrench or nut-driver installation without fastener slippage\u003c\/li\u003e\n\u003cli\u003eInch-system sizing (4-40 thread, 5\/16-inch OAL) integrates directly with standard domestic PCB hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation standoff for circuit board assemblies using 4-40 inch-series threaded fasteners in residential and commercial control panels and electronics enclosures.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electronics technicians or electricians during control board assembly or panel build-out. Always de-energize the equipment and follow lockout\/tagout procedures before working on or near live control boards. Use an appropriately sized hex wrench or nut driver sized to the 3\/16-inch width across flats to avoid rounding the hex body. Apply only hand-tight to snug torque consistent with 4-40 stainless fastener guidelines to prevent thread galling in the stainless material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Hex\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: 303\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Plain (Bright\/Uncoated)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\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\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.005 to +0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: P297M09F16440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51750346064178,"sku":"P297M09F16440","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fa4dd0ad0ef6decd6b3d494e5436f3e8.jpg?v=1788914925","url":"https:\/\/voomisupply.com\/products\/electro-hardware-p297m09f16440-hex-standoff-4-40","provider":"Voomi Supply","version":"1.0","type":"link"}
