Electro Hardware 1439M09F16-632 Hex Standoff 6-32 7/8 in

Product Description

The ELECTRO HARDWARE 1439M09F16-632 is a male-female hex circuit board standoff designed to create precise spacing between stacked PCBs or between a circuit board and a mounting surface. Machined from 18-8 and Grade 303 stainless steel with an anodized finish, this standoff offers corrosion resistance and dimensional consistency in both commercial and industrial electronic assemblies. It carries a 6-32 thread size with a 7/8-inch overall length, a 5/8-inch hex body, and conforms to fastener standard QQ-S-763. Electricians, electronics technicians, and panel builders use these standoffs when assembling control boards, relay panels, and enclosure-mounted circuit boards.

This standoff is suited for use in residential and commercial electrical control panels, HVAC control board assemblies, industrial enclosures, and any application requiring a rigid, threaded PCB mounting solution. The male-female configuration allows boards to be stacked in series using a single continuous fastener path. The 1/4-inch width across flats allows standard hex tooling. Applications include mounting logic boards, relay boards, and terminal block carriers in electrical and HVAC equipment enclosures where vibration resistance and dimensional accuracy are required.

Key Features

• 6-32 male-female thread configuration for stackable PCB mounting
• 7/8-inch overall length with 5/8-inch hex body and 1/4-inch male thread length
• 3/8-inch female thread depth for secure fastener engagement
• 18-8 and Grade 303 stainless steel construction with anodized finish for corrosion resistance
• Hex body profile at 1/4-inch width across flats for wrench or nut driver installation
• Meets QQ-S-763 fastener standard with tight length tolerance of plus or minus 0.005 inches

Compatibility

Designed as a standard 6-32 threaded male-female hex standoff for use in circuit board mounting applications requiring a 7/8-inch overall standoff height and 1/4-inch hex drive across flats.

Installation Notes

Installation is typically performed by an electrician or electronics technician during panel assembly or control board replacement. Power down and de-energize all circuits in the enclosure before installing or removing standoffs from live panels. Use a 1/4-inch hex nut driver or appropriately sized wrench to drive and torque the standoff without stripping the hex flats. Verify thread engagement on both the male and female ends before fully seating the mating fastener to avoid cross-threading.
