Electro Hardware P505M07F16-440 Female Standoff 4-40

Product Description

The ELECTRO HARDWARE P505M07F16-440 is a round female standoff designed for use in electronic and mechanical assemblies requiring compact, threaded spacer hardware. This fully threaded standoff accepts a 4-40 thread and measures 0.125 inches in overall length with a 0.25 inches outside diameter. Constructed from 18-8 or Grade 303 stainless steel with a bright finish, it delivers corrosion resistance and dimensional consistency in tight-tolerance applications. Electricians, electronics technicians, and mechanical assemblers install these standoffs to create fixed spacing between circuit boards, panels, and enclosure components.

This standoff is suited for use in residential and commercial panel assemblies, electronic enclosures, and instrumentation mounting applications. Its compact 0.125 inches body length makes it appropriate for densely populated boards or shallow-clearance installations where standard-length standoffs would not fit. The 0.5 inches thread depth provides positive thread engagement relative to the body length, supporting secure fastener retention in lightweight assemblies.

Key Features

• 4-40 female thread with 0.5 inches thread depth for secure fastener engagement
• Fully threaded body for consistent clamping across the entire standoff length
• 18-8 and Grade 303 stainless steel construction for corrosion resistance
• Bright finish meets QQ-S-763 fastener standard
• Round body shape with 0.25 inches OD for compatibility with standard mounting holes
• Compact 0.125 inches OAL designed for tight-clearance panel and PCB assemblies

Compatibility

Designed as a standard inch-series female standoff for use in electronic enclosures, PCB assemblies, and panel mounting applications requiring a 4-40 threaded spacer.

Installation Notes

Installation typically requires a hex driver or socket matched to the standoff OD. Power down all equipment and discharge any capacitors before working inside electronic enclosures. Avoid over-torquing stainless steel fasteners, as galling can occur without anti-seize compound. Follow applicable NEC guidelines when installing hardware inside electrical panels or control enclosures.
