Electro Hardware 1369M09F16256 Hex Standoff 2-56 2.25in

Product Description

The ELECTRO HARDWARE 1369M09F16256 is a male-female hex circuit board standoff designed to create precise vertical spacing between stacked PCBs or between a circuit board and a mounting surface. Machined from 303 stainless steel with a bright uncoated finish, this standoff meets the QQ-S-763 fastener standard. It features a 2-56 thread size, an overall body length of 2.25 inches, and a hex body shape measuring 0.1875 inches across the flats. The male thread length is 0.15625 inches and the female thread depth is 0.1875 inches. Electronics assemblers, field service technicians, and industrial maintenance professionals install this hardware in both commercial and industrial circuit board assemblies.

This standoff is suited for use in electronic enclosures, control panels, and instrumentation assemblies where corrosion resistance and dimensional stability are required. The 2-56 thread size is common in compact PCB mounting applications. Its stainless steel construction makes it appropriate for environments where mild exposure to moisture or chemicals is a concern. The bright uncoated finish provides a clean appearance without adding coating thickness that could affect fit in tight tolerances.

Key Features

• 303 stainless steel construction meets QQ-S-763 fastener standard for material compliance
• Male-female configuration allows modular board stacking with a single fastener at each standoff location
• Hex body shape at 0.1875 inches across the flats enables wrench or socket installation and removal
• 2-56 thread size with 2.25 inches overall body length provides precise board-to-board or board-to-panel spacing
• Bright uncoated finish maintains dimensional accuracy where coating buildup would affect fit

Compatibility

Designed as an OEM-style replacement or new-installation standoff for circuit board assemblies using 2-56 threaded hardware with hex body geometry.

Installation Notes

Installation is typically performed by electronics assemblers or instrumentation technicians using a hex driver or open-end wrench sized for the 0.1875-inch flats. De-energize all circuits and discharge any stored energy in the board assembly before installing or removing standoffs. Avoid overtightening, as the 2-56 thread is small-diameter and susceptible to stripping or galling, even in stainless steel. Follow applicable assembly drawings and IPC standards for torque guidance and board handling procedures.
