Machined from grade 303 stainless steel with a bright, uncoated finish, this standoff meets QQ-S-763 specification. The M2.5 x 0.45 thread runs male on one end and female on the other, with an overall length of 27.97 mm (approximately 1.10 inches) and a body length of 24.00 mm. The hexagonal body measures 4.5 mm across flats, allowing standard hex tooling for installation. Electronics assembly technicians and PCB integration specialists use this fastener in both production and field-service applications.\u003c\/p\u003e\n\u003cp\u003eThis standoff is suited for metric-threaded PCB mounting applications in commercial electronics, industrial control panels, HVAC control boards, and similar assemblies where stainless steel corrosion resistance is required. It is appropriate for use in environments where carbon steel hardware would be unsuitable. The M2.5 x 0.45 thread size is common in lightweight electronic assemblies and compact control modules.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMale-female hex configuration allows stackable PCB mounting with a single fastener type\u003c\/li\u003e\n  \u003cli\u003eGrade 303 stainless steel construction meets QQ-S-763 fastener standard\u003c\/li\u003e\n  \u003cli\u003eOverall length of 27.97 mm with a length tolerance of -0.150 to +0.150 mm\u003c\/li\u003e\n  \u003cli\u003e4.5 mm hex body width accepts standard metric hex drivers and wrenches\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish maintains dimensional accuracy and avoids coating buildup on threads\u003c\/li\u003e\n  \u003cli\u003eThread length of 3.97 mm on the male end; thread depth of 4.80 mm on the female end\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for metric M2.5 x 0.45 threaded PCB and panel mounting applications.

Power down and de-energize any control board or panel completely before installing or removing standoffs. Do not overtighten  -  stainless steel fasteners at this size are susceptible to galling; apply appropriate anti-seize compound if repeated removal is expected. Minimum order quantity is 10 units.\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 \/ Female\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 27.97 mm (approximately 1.10 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 24.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length (Male)\u003c\/strong\u003e: 3.97 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Depth (Female)\u003c\/strong\u003e: 4.80 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 4.5 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, 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\u003eLength Tolerance\u003c\/strong\u003e: -0.150 to +0.150 mm\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: 0.0084 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: MMF1339M0916M25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51740238348594,"sku":"MMF1339M0916M25","price":78.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ba7ad5e9b9bf9dbcf946f2b415f5ea93_79f6cf30-6275-4c76-816a-81e6aa29accd.jpg?v=1788823690","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mmf1339m0916m25-hex-standoff-m2-5","provider":"Voomi Supply","version":"1.0","type":"link"}
