Electro Hardware 1308M09F16256 Hex Standoff 2-56

Product Description

The ELECTRO HARDWARE 1308M09F16256 is a male-female hex circuit board standoff designed to create fixed spacing between stacked PCBs or between a circuit board and a mounting surface. The standoff features a 2-56 thread size with a hex body shape measuring 3/16 inches across flats. The overall body length is 0.3438 inches (11/32 inch), and the part is machined from 303 stainless steel with a passivated finish that meets the QQ-S-763 federal specification. This type of hardware is installed by electronics technicians, control board assemblers, and field service technicians working on HVAC control assemblies, panel boards, and similar equipment.

This standoff is used in applications where a threaded male post on one end and a threaded female receptacle on the other end are needed to fasten and space circuit boards in control enclosures, HVAC equipment, and light industrial assemblies. The passivated stainless steel construction makes it suitable for environments where corrosion resistance is a priority. The 2-56 thread is a fine-pitch fastener standard common in printed circuit board and precision instrument assemblies. Package quantity is 1 piece; minimum order quantity is 5 pieces.

Compatibility

Designed as a standard 2-56 male-female hex circuit board standoff for use in any PCB assembly or control enclosure application requiring 2-56 threaded hardware and a hex body measuring 3/16 inch across flats.

Installation Notes

Install using a hex driver or open-end wrench sized for 3/16 inch across flats. Always de-energize and discharge the circuit board assembly before installing or removing standoffs to prevent damage to sensitive components. Confirm thread engagement on both the male and female ends before applying torque to avoid cross-threading. Follow applicable IPC assembly standards and the equipment manufacturer's documentation for required spacing and fastener placement.
