Threaded 4-40 on the female end, this standoff accepts a matching male 4-40 screw to stack or secure boards at a consistent height. The body measures 0.25 inches overall length with a 0.25-inch width across flats, making it suited for tight, low-profile board layouts. Manufactured from 18-8 and Grade 303 stainless steel with an anodized bright finish, the part meets QQ-S-763 fastener standards. It is installed by electronics technicians and field service professionals working on control boards in HVAC, electrical, and industrial panel applications.\u003c\/p\u003e\u003cp\u003eThis standoff is used wherever a PCB requires a secure, non-conductive or corrosion-resistant hex spacer in residential and commercial electronic enclosures. The 4-40 thread size is common in low-voltage control boards, relay panels, and instrumentation chassis. Its compact 0.25-inch profile fits densely packed board layouts where larger standoffs would not clear adjacent components. It ships individually and is ordered as a single unit per package.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFemale 4-40 threaded body accepts standard 4-40 male screws for board stacking or surface mounting\u003c\/li\u003e\n\u003cli\u003e0.25-inch overall length suits low-profile PCB spacing requirements\u003c\/li\u003e\n\u003cli\u003eHex body shape allows torque application with standard nut drivers or hex wrenches\u003c\/li\u003e\n\u003cli\u003e18-8 and Grade 303 stainless steel construction provides corrosion resistance in humid or wash-down environments\u003c\/li\u003e\n\u003cli\u003eAnodized bright finish meets QQ-S-763 stainless steel fastener standard\u003c\/li\u003e\n\u003cli\u003eLength tolerance of -0.005 to 0.005 inches ensures consistent board-to-board spacing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service standoff for circuit boards using 4-40 threaded fastener patterns in electronic control assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electronics technicians or licensed electricians working on control panels and PCB assemblies. De-energize and lock out all power to the panel or board before removing or installing standoffs. Use a properly sized hex driver or nut driver matched to the 0.25-inch across-flats dimension to avoid rounding the hex body. Follow applicable NEC guidelines when working inside electrical enclosures.\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: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.25 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: 18-8 \/ Grade 303\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Anodized Bright\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\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\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: P513M09F16-440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51739992654130,"sku":"P513M09F16-440","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/69be0ea513ec4cbce20afd5016302ef1_20949e32-0b3f-4692-a4c2-4cc5a2c68f49.jpg?v=1788821232","url":"https:\/\/voomisupply.com\/products\/electro-hardware-p513m09f16-440-female-hex-standoff-4-40","provider":"Voomi Supply","version":"1.0","type":"link"}
