Electro Hardware 1311M19F16256 Hex Nylon Standoff 2-56

Product Description

The ELECTRO HARDWARE 1311M19F16256 is a male-female hex circuit board standoff designed to create precise spacing between PCBs and mounting surfaces in electronic assemblies. Made from nylon with a bright uncoated finish, this fastener meets MIL-P-17091B standards, making it a reliable choice for defense-grade and industrial electronics work. The standoff features a 2-56 thread size, a body length of 7/16 inch (0.4375 inch decimal), and a width across flats of 3/16 inch. With a tensile strength of 16,500 psi, this nylon standoff delivers the structural integrity needed for secure board mounting without conductive interference.

This standoff is used in PCB assembly, enclosure builds, and electronics manufacturing and repair environments where non-conductive spacing hardware is required. The male-female configuration allows stacking of multiple boards or securing a single board at a fixed height above a chassis or panel. It is a standard fit for circuit board assemblies calling for 2-56 hardware in both commercial electronics and MIL-spec applications. Electronics technicians and PCB assembly professionals typically install this type of hardware during initial board mounting or repair rework.

Key Features

• MIL-P-17091B compliant nylon construction for non-conductive, corrosion-resistant performance
• Male-female hex body configuration allows board stacking and precise standoff height control
• 2-56 thread size with a thread depth of 3/16 inch and thread length of 5/32 inch
• Body length of 7/16 inch with a tight length tolerance of -0.005 to 0.005 inch
• Hexagonal body profile (3/16 inch across flats) for wrench engagement during installation
• Tensile strength of 16,500 psi for reliable mechanical holding in PCB assemblies

Compatibility

Designed as an OEM-style replacement or new-installation standoff for circuit board assemblies using 2-56 inch-series threaded hardware in hex standoff configurations.

Installation Notes

Installation is typically performed by electronics technicians or PCB assembly professionals using a nut driver or hex wrench sized for 3/16 inch across flats. Always de-energize and discharge the circuit board assembly before installing or removing standoffs. Hand-tighten first, then apply tool torque carefully to avoid cracking the nylon body. Do not over-torque, as nylon fasteners are more susceptible to thread stripping than metal hardware.
