Electro Hardware 1310M19F16440 Hex Nylon Standoff 4-40

Product Description

The ELECTRO HARDWARE 1310M19F16440 is a male-female hex circuit board standoff machined from nylon for use in electronic assemblies and PCB mounting applications. The standoff accepts a 4-40 thread on both the male pin end and the female threaded bore, allowing boards to be stacked or elevated from a chassis surface. The body is hex-shaped at 3/16 inches across flats, with an overall length of 0.4063 inches (13/32 inch) and a thread depth of 1/4 inch. Tensile strength is rated at 16,500 psi. The uncoated bright nylon finish meets MIL-P-17091B fastener standard. Electronics technicians and PCB assembly personnel install this standoff during board-level build and rework operations.

This standoff is suited for residential and commercial electronic control board assemblies, HVAC control boards, and general PCB mounting wherever a non-conductive nylon spacer is required. The male-female configuration allows multiple boards to be stacked in series or a single board to be secured off a mounting surface with thread engagement on both ends. It is appropriate for any application calling for a 4-40 nylon hex standoff conforming to MIL-P-17091B tolerances.

Key Features

• 4-40 male-female thread configuration for board stacking or chassis mounting
• Nylon construction provides electrical isolation between board and mounting surface
• Hex body at 3/16 inches across flats allows wrench or driver installation
• Overall length of 0.4063 inches with length tolerance of -0.005 to 0.005 inches
• Tensile strength of 16,500 psi for reliable mechanical retention
• Meets MIL-P-17091B fastener standard, uncoated bright finish

Compatibility

Designed as a standard 4-40 male-female hex nylon circuit board standoff for use in PCB assemblies, electronic enclosures, and control board mounting applications requiring MIL-P-17091B conformance.

Installation Notes

Installation is typically performed by electronics assembly technicians or field service personnel during board replacement or new assembly work. Power down and de-energize the equipment fully before handling any circuit board or standoff hardware. A hex driver or small wrench sized to 3/16 inches across flats is used to engage the hex body without damaging the nylon. Do not overtighten, as nylon threads can strip or crack under excessive torque.
