Electro Hardware MP1049M09F16M4 Female Hex Standoff M4

Product Description

The ELECTRO HARDWARE MP1049M09F16M4 is a female hex circuit board standoff designed to create fixed spacing between PCBs, mounting panels, or chassis components in electronic assemblies. Machined from 303 stainless steel with a plain, bright uncoated finish, it meets the QQ-S-763 federal specification for corrosion-resistant steel fasteners. The standoff features an M4 x 0.7 female thread, a 25 mm overall length with a full 25 mm thread depth, and a 6 mm hex body width across flats. Hex geometry allows standard wrench or nut driver engagement for secure, consistent torque during installation. Electrical and electronics technicians, PCB assembly professionals, and panel builders commonly use this hardware in control enclosures, instrumentation, and industrial electronics.

This standoff is suited for metric-threaded PCB mounting applications in both commercial and industrial environments. The M4 x 0.7 thread pitch is a common standard in electronics chassis work, instrumentation panels, and embedded control systems. Stainless steel construction makes it appropriate for environments where mild corrosion resistance is required, such as outdoor enclosures, HVAC control boards, or light industrial panels. The QQ-S-763 certification supports use in applications where material traceability and specification compliance are required by the project or customer.

Key Features

• M4 x 0.7 female thread for secure metric fastener engagement
• 25 mm overall length with full 25 mm thread depth for maximum thread engagement
• 6 mm hex body width across flats for wrench or nut driver installation
• 303 stainless steel construction meeting QQ-S-763 specification
• Plain, bright uncoated finish with length tolerance of -0.13 to 0.13 mm
• Hex body shape provides positive anti-rotation engagement in panel cutouts

Compatibility

Designed as an OEM-style metric hex standoff for use with M4 x 0.7 threaded fasteners in PCB mounting, chassis assembly, and panel fabrication applications requiring QQ-S-763 compliant stainless steel hardware.

Installation Notes

Installation is typically performed by electronics assembly technicians or electricians working on control panel builds. Power down all assemblies before installing or removing standoffs near live circuits. Use a wrench or nut driver sized for 6 mm across flats to seat the standoff without over-driving. NEC and applicable enclosure standards should be followed when mounting standoffs inside electrical panels or enclosures.
