Electro Hardware 1305M19F16256 Hex Nylon Standoff 2-56

Product Description

The ELECTRO HARDWARE 1305M19F16256 is a male-female hex circuit board standoff machined from nylon, designed to mount and space printed circuit boards within electronic enclosures and control assemblies. The standoff features a 2-56 thread size with a male thread on one end and a female threaded bore on the other, allowing boards to stack or mount at a fixed distance from a panel. The hex body measures 3/16 inches across flats and provides a wrench-engagement surface for installation with standard hex tools. Overall body length is 0.25 inches with a thread depth of 3/16 inches and a thread length of 5/32 inches. Tensile strength is rated at 16,500 psi. This fastener meets MIL-P-17091B standards and carries a bright, uncoated finish.

This standoff is used in residential and commercial HVAC control boards, electrical enclosures, motor drives, and any application requiring non-conductive PCB mounting hardware. The nylon construction provides electrical isolation between the board and the mounting surface, making it appropriate for low-voltage control circuits and sensitive electronic assemblies. Electricians, control panel builders, and HVAC technicians working with field-replaceable control boards are the typical installers of this hardware.

Key Features

• Male-female hex configuration allows stacking or panel-mount installation in a single fastener
• Nylon construction provides electrical isolation and corrosion resistance
• 2-56 thread size suits standard PCB mounting hole patterns
• Meets MIL-P-17091B fastener standard for dimensional and material compliance
• Hex body profile accepts standard nut drivers and hex wrenches for secure torquing
• Bright uncoated finish with tight length tolerance of plus or minus 0.005 inches

Compatibility

Designed as an OEM-style replacement or new-install standoff for circuit board mounting applications requiring a 2-56 thread, nylon hex standoff with a 0.25-inch body length.

Installation Notes

Installation is performed by electricians or electronics technicians during control board assembly or replacement. De-energize the control circuit and discharge any capacitors before handling PCB hardware. Use a properly sized nut driver or hex wrench matched to the 3/16-inch hex flats to avoid stripping the nylon body. Do not overtighten, as nylon standoffs are subject to thread damage under excessive torque.
