Manufactured from brass with a clear zinc chromate finish meeting ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, this standoff provides reliable electrical isolation and mechanical support. The M2.5 x 0.45 metric thread accepts a mating male fastener on the open end while the partially threaded interior offers a 4.8 mm thread depth. With a 23 mm overall length and 4.5 mm width across flats, it suits compact board-level spacing applications in control panels, HVAC control boards, and similar electronic enclosures.\u003c\/p\u003e\u003cp\u003eThis standoff is used in residential and commercial electronic assemblies where metric M2.5 hardware is specified. Typical install scenarios include mounting control boards inside HVAC equipment, variable-speed drive enclosures, and electrical panel sub-assemblies. The hex body allows wrench engagement for secure, torque-controlled installation. Electricians, controls technicians, and electronics assembly technicians commonly handle this hardware during board-level service or OEM-style replacement builds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFemale hex body accepts M2.5 x 0.45 male fastener for board-to-board or board-to-chassis spacing\u003c\/li\u003e\n\u003cli\u003e23 mm overall length with 4.8 mm partial thread depth for secure mating engagement\u003c\/li\u003e\n\u003cli\u003e4.5 mm width across flats enables standard hex wrench or socket installation\u003c\/li\u003e\n\u003cli\u003eBrass construction with clear zinc chromate finish resists corrosion in enclosure environments\u003c\/li\u003e\n\u003cli\u003eMeets ASTM B633 Type 1 and QQ-B-626 Comp 22 finish standards\u003c\/li\u003e\n\u003cli\u003eMetric measurement system  -  compatible with M2.5 fastener ecosystems used in control and electronics applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a metric M2.5 x 0.45 female hex standoff for use in circuit board mounting applications requiring a 23 mm standoff height and 4.5 mm hex body format.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by electronics assembly technicians or controls technicians using a hex wrench or open-end wrench sized for 4.5 mm across flats. De-energize all equipment fully before working on any control board or enclosure interior. Do not overtighten  -  brass hardware is subject to thread damage if excessive force is applied.
