It features a brass body with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-B-626 Comp 22 standards. The standoff measures 1.375 inches in overall length with a 1 inch hex body, a 3\/8 inch male thread length, and a 7\/16 inch female thread depth. The 8-32 thread size and 0.25 inch width across flats make this a standard hardware item used by electricians, control panel builders, and electronics technicians in both commercial and industrial settings.\u003c\/p\u003e\u003cp\u003eThis standoff is used in circuit board mounting applications where a fixed, measured offset between a board and a chassis or between stacked boards is required. The hex body allows installation and removal with standard hex drivers or wrenches, making it well suited for control panels, HVAC circuit board assemblies, electrical enclosures, and similar applications where secure, repeatable board spacing is necessary. The zinc-plated brass construction provides corrosion resistance appropriate for indoor control environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMale-female thread configuration allows stacking or panel-to-board mounting in a single fastener\u003c\/li\u003e\n\u003cli\u003eBrass base material with zinc-plated finish per ASTM B633 Type 1 and QQ-B-626 Comp 22\u003c\/li\u003e\n\u003cli\u003e8-32 thread size with 0.25 inch width across flats for use with standard hex tooling\u003c\/li\u003e\n\u003cli\u003e1.375 inch overall length with 1 inch hex body and 3\/8 inch male thread extension\u003c\/li\u003e\n\u003cli\u003eLength tolerance of -0.005 to +0.005 inches for consistent board spacing\u003c\/li\u003e\n\u003cli\u003eHex body shape allows positive torque without slipping during installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 8-32 male-female hex circuit board standoff for use in control panels, PCB assemblies, and electrical enclosures requiring a 1.375 inch board offset with inch-system fasteners.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by electricians or control panel assemblers using a hex driver or open-end wrench sized to 0.25 inch across flats. De-energize all circuits and discharge any stored energy in the assembly before installing or removing circuit board standoffs. Avoid overtightening, as brass threads can be damaged by excessive torque. Confirm thread engagement depth is sufficient on both the male and female ends before applying load to the board.\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: 8-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length (Male)\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Depth (Female)\u003c\/strong\u003e: 7\/16 inch\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 Shape\u003c\/strong\u003e: Hex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\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\u003eStandards\u003c\/strong\u003e: ASTM B633 Type 1, QQ-B-626 Comp 22\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: 1451M03F21-832\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51730363908402,"sku":"1451M03F21-832","price":16.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/173ca1ac0d14a84db5bbebb78d30240f.jpg?v=1788716087","url":"https:\/\/voomisupply.com\/products\/electro-hardware-1451m03f21-832-hex-standoff-8-32","provider":"Voomi Supply","version":"1.0","type":"link"}
