Machined from 18-8 and Grade 303 stainless steel with a bright finish, this standoff provides corrosion resistance and dimensional consistency where it matters most. It features a 4-40 thread size with a 1\/2 inch thread depth, a 5\/8 inch overall length, and a 1\/4 inch outside diameter. The fully threaded female configuration accepts standard 4-40 male fasteners on both ends, making it a straightforward solution for stacking boards, mounting panels, or maintaining fixed spacing between components in assemblies built to tight tolerances.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for electronic enclosures, control panels, instrumentation racks, and light mechanical assemblies where a compact, corrosion-resistant spacer is required. The inch-based dimensioning and QQ-S-763 compliance make it appropriate for both commercial and government-specification work. Electricians, panel builders, and electronics assembly technicians are the most common installers. The small form factor fits high-density layouts where a 1\/4 inch OD profile is necessary to avoid interference with adjacent components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18-8 and Grade 303 stainless steel construction for corrosion resistance in demanding environments\u003c\/li\u003e\n  \u003cli\u003e4-40 female thread with 1\/2 inch thread depth for secure engagement with standard fasteners\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch overall length and 1\/4 inch outside diameter for compact, high-density panel layouts\u003c\/li\u003e\n  \u003cli\u003eBright finish for clean appearance and consistent surface quality\u003c\/li\u003e\n  \u003cli\u003eFully threaded female body allows through-bolt or stud fastening on both ends\u003c\/li\u003e\n  \u003cli\u003eMeets QQ-S-763 federal specification for stainless steel fasteners\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation standoff for assemblies requiring a 4-40 thread, 5\/8 inch overall length, round female stainless steel spacer conforming to QQ-S-763.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by hand or with standard hex drivers appropriate for the 4-40 thread size. De-energize any panel or control board completely before installing or removing standoffs in live electrical enclosures. Avoid over-torquing small-diameter stainless fasteners, as galling can occur without lubrication or anti-seize compound on the threads. Follow applicable NEC or equipment manufacturer guidelines for fastener spacing and grounding continuity in electrical panels.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eThread Depth\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.625 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\u003eOutside Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Round\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: Bright\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\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: P537M07F16-440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51741932552498,"sku":"P537M07F16-440","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/215fccf0ef82d1a65d77b571fda0d4f4.jpg?v=1788834407","url":"https:\/\/voomisupply.com\/products\/electro-hardware-p537m07f16-440-female-standoff-4-40","provider":"Voomi Supply","version":"1.0","type":"link"}
