Electro Hardware P577M07F16-832 Round Female Standoff

Product Description

The ELECTRO HARDWARE P577M07F16-832 is a round female standoff used to create fixed spacing between panels, PCBs, enclosures, or structural assemblies. It features an 8-32 internal thread with a 1 inch thread depth and measures 1.25 inches overall length with a 0.25 inch outside diameter. The body is fully threaded and machined from 18-8 and Grade 303 stainless steel with a bright finish, making it suitable for corrosion-resistant applications. Electricians, panel fabricators, and mechanical assemblers use standoffs like this when building control enclosures, mounting circuit boards, or stacking sheet metal components at a precise, consistent offset.

This standoff is appropriate for both light industrial and commercial assembly work where a female-threaded receiver is needed at each end of a spacer column. Typical applications include electrical panel construction, instrumentation enclosures, PCB mounting stacks, and equipment chassis assembly. The inch-system dimensions and standard 8-32 thread make it compatible with common machine screws used throughout North American trade and manufacturing environments. Fabricators working to tight dimensional tolerances will note the length tolerance of -0.005 to +0.005 inches.

Key Features

• 8-32 internal thread, fully threaded body with 1 inch thread depth
• 1.25 inch overall length and 0.25 inch outside diameter for precise panel spacing
• 18-8 and Grade 303 stainless steel construction for corrosion resistance
• Bright finish meets QQ-S-763 fastener standard
• Length tolerance of -0.005 to +0.005 inches for close-tolerance assemblies
• Round body shape - compatible with standard hex-driver or smooth-bore tooling

Compatibility

Designed for use with standard 8-32 machine screws in inch-system assemblies including electrical enclosures, PCB mounting configurations, and control panel fabrication.

Installation Notes

Installation is performed by hand or with a hex key, socket, or pin-spanner depending on the drive style of the mating screw. Ensure mating screws are 8-32 and of appropriate length to engage the full thread depth without bottoming out. Degrease mating surfaces before assembly in environments subject to vibration or moisture. Follow applicable NEC or equipment manufacturer guidelines when mounting standoffs inside energized enclosures - de-energize the panel before working inside.
