Electro Hardware 1321M19F16256 Hex Nylon Standoff 2-56

Product Description

The ELECTRO HARDWARE 1321M19F16256 is a male-female hex circuit board standoff machined from nylon and designed to create precise spacing between PCBs or between a board and a chassis. The standoff features a 2-56 unified thread on both the male and female ends, a hexagonal body with a width across flats of 0.1875 inches (3/16 inches), and an overall body length of 0.75 inches (3/4 inches). It carries a tensile strength rating of 16,500 psi and meets MIL-P-17091B fastener standards. Electricians, electronics technicians, and OEM assembly technicians install these standoffs during control board mounting in HVAC equipment, industrial panels, and other enclosures where non-conductive hardware is required.

This standoff is suited for residential and commercial applications where electrical isolation between stacked circuit boards or between a board and a metal mounting surface is necessary. The nylon material prevents galvanic corrosion and eliminates the risk of short circuits caused by conductive fasteners. Typical use cases include mounting control boards inside HVAC equipment, securing relay boards in electrical panels, and stacking PCBs in OEM assembly environments. The bright, uncoated finish keeps the standoff at its molded dimensions without affecting thread fit. The package quantity is 1 piece, with a minimum order quantity of 5 pieces.

Key Features

• Male-female hex body allows stacking or panel-mounting of circuit boards with a single fastener per point
• Nylon construction provides electrical isolation and corrosion resistance
• 2-56 thread size on both ends suits standard small-pitch PCB mounting hardware
• Overall body length of 0.75 inches creates consistent board-to-board or board-to-chassis spacing
• Meets MIL-P-17091B fastener standard with a tensile strength of 16,500 psi
• Bright, uncoated finish maintains dimensional accuracy out of the package

Compatibility

Designed as a standard OEM-style nylon hex standoff for circuit board mounting applications requiring a 2-56 thread and a 3/4-inch standoff height in equipment assemblies where non-conductive fasteners are specified.

Installation Notes

Installation is performed by electronics technicians or qualified electrical workers. De-energize and discharge the board or assembly before handling any PCB-mounted hardware. Use a hex driver or nut driver sized for 3/16-inch flats to seat the standoff without over-torquing, which can crack nylon threads. Verify thread engagement depth against the mating board thickness before final assembly.
