Machined from grade 303 stainless steel with a bright uncoated finish, it meets the QQ-S-763 fastener standard. The M2.5 x 0.45 metric thread runs on both the male pin end and the female threaded bore, allowing boards to be stacked or mounted with consistent spacing. Overall length is 16.97 mm (0.668 inches) with a hex body measuring 13.00 mm (0.512 inches) and a width across flats of 4.50 mm (0.177 inches). Electronics assemblers, PCB technicians, and industrial maintenance electricians use this standoff wherever corrosion resistance and dimensional precision are required.\u003c\/p\u003e\u003cp\u003eThis standoff is suited for use in electronic control panels, HVAC control boards, industrial enclosures, and similar low-voltage circuit board assemblies that require reliable board-to-board or board-to-chassis spacing. The metric M2.5 x 0.45 thread size is common in compact PCB layouts. Its stainless steel construction makes it appropriate for environments where mild corrosion resistance is a factor. Thread depth on the female end is 4.80 mm (0.189 inches) and thread length on the male end is 3.97 mm (0.156 inches), providing defined engagement depth for consistent torque and pull-out resistance during assembly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 303 stainless steel construction meets QQ-S-763 fastener standard\u003c\/li\u003e\n\u003cli\u003eM2.5 x 0.45 metric thread on both male pin and female bore ends\u003c\/li\u003e\n\u003cli\u003eHex body shape allows standard hex driver or wrench installation\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish for bare metal corrosion resistance without added coating thickness\u003c\/li\u003e\n\u003cli\u003eLength tolerance of -0.150 mm to +0.150 mm ensures consistent board spacing\u003c\/li\u003e\n\u003cli\u003eOverall weight of approximately 0.012 pounds per piece  -  negligible panel load\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a metric M2.5 x 0.45 male-female hex standoff for use in circuit board assemblies and electronic enclosures requiring QQ-S-763 compliant stainless steel hardware.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by electronics assemblers or electricians working on control board assemblies. Power down and de-energize all circuits before installing or removing standoffs from live control boards. Use an appropriately sized hex driver or nut driver matched to the 4.50 mm width across flats to avoid rounding the hex body. Verify female thread engagement depth against the mating fastener to ensure full thread capture without bottoming out.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 16.97 mm (0.668 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 13.00 mm (0.512 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Depth (Female)\u003c\/strong\u003e: 4.80 mm (0.189 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length (Male)\u003c\/strong\u003e: 3.97 mm (0.156 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 4.50 mm (0.177 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: Stainless Steel, Grade 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: 0.012 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: MMF1317M0916M25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51741148840242,"sku":"MMF1317M0916M25","price":37.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ba7ad5e9b9bf9dbcf946f2b415f5ea93_fe23f911-601c-47f7-b3ce-3743e1b19879.jpg?v=1788829623","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mmf1317m0916m25-hex-standoff-m2-5","provider":"Voomi Supply","version":"1.0","type":"link"}
