Machined from 303 stainless steel with a bright uncoated finish, this standoff meets the QQ-S-763 fastener standard. It features an M4 x 0.7 thread on both the male and female ends, a 6 mm width across flats for standard hex tooling, and an overall length of 22.53 mm (approximately 0.888 inches). The hex body length is 13.00 mm (approximately 0.512 inches). Electronics assembly technicians and PCB assembly professionals are the primary installers of this hardware.\u003c\/p\u003e\u003cp\u003eThis standoff is used in electronics enclosure assembly, PCB stacking applications, and control board mounting in commercial and industrial settings. The male end threads into a mating female standoff or threaded insert, while the female end accepts a machine screw from the next board in the stack. Typical applications include control panel assemblies, HVAC control board mounting, and instrumentation enclosures where metric M4 hardware is specified. The stainless steel construction makes it suitable for environments with moderate corrosion exposure.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMale-female configuration allows modular PCB stacking with standard M4 x 0.7 metric threads\u003c\/li\u003e\n\u003cli\u003e303 stainless steel construction meets QQ-S-763 fastener standard\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish for a clean, low-contamination surface in sensitive electronics environments\u003c\/li\u003e\n\u003cli\u003eHex body profile accepts standard 6 mm hex drivers and wrenches for secure installation and removal\u003c\/li\u003e\n\u003cli\u003eTight length tolerance of -0.150 to 0.150 mm ensures consistent board spacing across assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in metric M4 x 0.7 PCB stacking and circuit board mounting applications where QQ-S-763 compliant stainless steel standoff hardware is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by electronics assembly technicians or field service engineers working on control boards and enclosures. Ensure the mating board, insert, or standoff is fully de-energized and discharged before installing or removing standoffs. Use a 6 mm hex driver or wrench for proper engagement; avoid pliers or tools that may damage the hex flats or contaminate the board surface. Apply only hand-tight torque appropriate for M4 stainless hardware and follow any applicable IPC assembly standards for the enclosure or board type being serviced.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Male and Female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M4 x 0.7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 22.53 mm (approximately 0.888 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 13.00 mm (approximately 0.512 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 9.53 mm (approximately 0.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Depth\u003c\/strong\u003e: 11.10 mm (approximately 0.437 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Across Flats\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Shape\u003c\/strong\u003e: Hex\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\u003eMaterial\u003c\/strong\u003e: 303 Stainless Steel\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: 0.00952 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161816\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: MMF1817M09F16M4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51739530363186,"sku":"MMF1817M09F16M4","price":78.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ba7ad5e9b9bf9dbcf946f2b415f5ea93_91e4b86a-4e88-48a8-acb7-8a4443715ded.jpg?v=1788815786","url":"https:\/\/voomisupply.com\/products\/electro-hardware-mmf1817m09f16m4-hex-standoff-m4x0-7","provider":"Voomi Supply","version":"1.0","type":"link"}
