Machined from 18-8 and Grade 303 stainless steel with an anodized finish, this standoff meets the QQ-S-763 fastener standard. It features a 4-40 thread size, an overall length of 1.4375 inches (1-7\/16 inches), a hex body width across flats of 0.25 inches, and a body length of 1.25 inches. Electricians, electronics technicians, and control board service professionals use this hardware in panel assemblies, control enclosures, and instrumentation builds.\u003c\/p\u003e\u003cp\u003eThis standoff is suited for use in light commercial and residential control panels, HVAC control board assemblies, electrical enclosures, and similar applications where a corrosion-resistant, thread-through spacer is required. The male-female configuration allows daisy-chaining of multiple standoffs or direct fastening of a mating board using a standard 4-40 machine screw. The hex body shape enables wrench engagement for secure, torque-controlled installation in tight assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-40 male-female thread configuration supports stacked PCB assemblies\u003c\/li\u003e\n\u003cli\u003eOverall length of 1.4375 inches with a body length of 1.25 inches and thread length of 3\/16 inches\u003c\/li\u003e\n\u003cli\u003eHex body with 0.25 inch width across flats allows wrench tightening\u003c\/li\u003e\n\u003cli\u003e18-8 and Grade 303 stainless steel construction resists corrosion\u003c\/li\u003e\n\u003cli\u003eAnodized finish provides additional surface protection\u003c\/li\u003e\n\u003cli\u003eMeets QQ-S-763 fastener standard\u003c\/li\u003e\n\u003cli\u003eLength tolerance of -0.005 to 0.005 inches for precision fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 4-40 inch-series hex standoff for use in circuit board mounting, control enclosure assemblies, and instrumentation panels wherever a 4-40 male-female stainless steel spacer is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by electronics technicians or licensed electricians working on control boards or panel assemblies. De-energize all circuits and discharge any capacitors before handling PCBs or standoffs within live enclosures. Use a hex wrench or nut driver sized to the 0.25 inch flats to tighten the standoff without over-stressing the board. Follow applicable NEC guidelines when installing within electrical enclosures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Male\/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: 1.4375 inches (1-7\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 1.25 inches (1-1\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 0.25 inches (1\/4 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 and Grade 303\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Anodized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: QQ-S-763\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 1459M09F16-440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51744944718130,"sku":"1459M09F16-440","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/354e84e78593c87d91054c55b2ccfd1d_f490d341-8d5e-442c-8ac8-ffb1e52f6489.jpg?v=1788862519","url":"https:\/\/voomisupply.com\/products\/electro-hardware-1459m09f16-440-hex-standoff-4-40","provider":"Voomi Supply","version":"1.0","type":"link"}
