Machined from grade 303 stainless steel with a bright, uncoated finish, this standoff meets the QQ-S-763 fastener standard. The M2.5 x 0.45 thread size covers both the male and female ends, with an overall length of 19.97 mm and a body length of 16.00 mm. The hexagonal body measures 4.50 mm across flats, making it compatible with standard hex drivers. Electronics assemblers, OEM technicians, and PCB-level service professionals install this hardware during board stacking and chassis mounting operations.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for metric-threaded circuit board assemblies in industrial controls, HVAC control boards, power supplies, and general electronic enclosures where corrosion resistance and dimensional consistency are required. The stainless steel construction makes it appropriate for environments where mild chemical exposure or humidity is a concern. The male end threads into a mounting surface or lower board while the female end accepts the fastener securing the upper board, maintaining a fixed, repeatable gap throughout the assembly. Length tolerance is held to -0.150 to 0.150 mm for consistent stack height across multi-board builds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMale-female configuration supports multi-board stacking with a single fastener interface per standoff\u003c\/li\u003e\n  \u003cli\u003eGrade 303 stainless steel construction provides corrosion resistance without plating or coating\u003c\/li\u003e\n  \u003cli\u003eMeets QQ-S-763 fastener standard for material and dimensional compliance\u003c\/li\u003e\n  \u003cli\u003eM2.5 x 0.45 metric thread on both ends for compatibility with standard metric hardware\u003c\/li\u003e\n  \u003cli\u003e4.50 mm hex body width allows installation and removal with common hex wrenches or nut drivers\u003c\/li\u003e\n  \u003cli\u003eTight length tolerance of -0.150 to 0.150 mm ensures repeatable PCB stack height\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in metric M2.5 threaded circuit board assemblies requiring hex standoff hardware.

Always de-energize and discharge any boards or assemblies before installing or removing standoffs. Use a properly sized hex driver or nut driver matching the 4.50 mm across-flats dimension to avoid rounding the body. Do not over-torque metric standoffs into threaded inserts or PCB-mounted hardware, as thread stripping can damage the board.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M2.5 x 0.45\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Male and Female\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 19.97 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 16.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 3.97 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 4.80 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: -0.150 to 0.150 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 4.50 mm\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: 303\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: QQ-S-763\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.00624 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161816\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: MMF1323M0916M25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51743826084146,"sku":"MMF1323M0916M25","price":38.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ba7ad5e9b9bf9dbcf946f2b415f5ea93_6e8db467-8c3f-4ddf-88cb-fa7fcd02a3b8.jpg?v=1788850095","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mmf1323m0916m25-hex-standoff-m2-5","provider":"Voomi Supply","version":"1.0","type":"link"}
