Machined from steel with a clear zinc chromate finish meeting ASTM B633 Type 1 and QQ-S-633 standards, this standoff accepts a 4-40 thread and measures 1\/4 inch in overall length with a 3\/16 inch width across the hex flats. The fully threaded female interior runs the full 1\/4 inch thread depth. It is installed by HVAC controls technicians, electricians, and electronics assembly professionals during control board mounting and panel fabrication work.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for residential and light commercial control panel assemblies where compact board spacing is required. The 4-40 thread size is common in low-voltage control board applications, HVAC control panel enclosures, and general electronics chassis work. The hex body shape allows wrench or nut driver installation, making it practical for confined board layouts where finger tightening is not sufficient.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale fully threaded interior with 4-40 thread size and 1\/4 inch thread depth\u003c\/li\u003e\n  \u003cli\u003eHex body shape accepts standard nut driver or wrench for secure installation\u003c\/li\u003e\n  \u003cli\u003eSteel construction with clear zinc chromate finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM B633 Type 1 and QQ-S-633 finish standards\u003c\/li\u003e\n  \u003cli\u003eCompact 1\/4 inch overall length suits tight board-to-panel spacing requirements\u003c\/li\u003e\n  \u003cli\u003eLength tolerance of -0.005 to 0.005 inch for consistent stacking height\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 circuit board mounting applications requiring a 4-40 female threaded hex standoff with 1\/4 inch overall length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified HVAC technicians or electricians during control board replacement or panel assembly. De-energize all circuits and discharge any capacitors before working inside a control enclosure. Use a correctly sized nut driver or hex wrench on the flats to avoid rounding the hex body.
