Electro Hardware 1308M06F16440 Hex Standoff 4-40 3/16 in

Product Description

The ELECTRO HARDWARE 1308M06F16440 is an aluminum male-female hex circuit board standoff designed to space and fasten printed circuit boards within electronic enclosures and control assemblies. Machined to a 4-40 thread size with a 3/16-inch width across flats, this standoff features a male thread on one end and a female threaded bore on the other, allowing boards to be stacked or mounted at a fixed distance from a chassis or adjacent board. Overall body length is 0.3438 inches (11/32 inch), with a thread depth of 1/4 inch and a thread length of 3/16 inch. Material grade is T3 aluminum with a bright uncoated finish, meeting QQ-A-225A Comp 2 specification.

This standoff is used in residential and commercial electronic control assemblies, HVAC control boards, relay panels, and general industrial circuit board mounting applications. It is commonly installed by electronics technicians, control panel builders, and HVAC service professionals during circuit board replacement or panel fabrication. The hex body shape allows for easy installation with standard hex drivers or nut drivers in confined board-level spaces where consistent standoff height is required.

• Length tolerance held to -0.005 to 0.005 inches for consistent fitment

Compatibility

Designed as an OEM-style replacement or new-installation standoff for circuit board assemblies requiring a 4-40 thread, 3/16-inch hex, aluminum male-female standoff per QQ-A-225A Comp 2.

Installation Notes

Installation is typically performed by electronics or controls technicians using a standard hex or nut driver sized for a 3/16-inch hex body. De-energize all circuits and discharge any stored energy in the board assembly before handling or mounting circuit boards. Avoid over-torquing the aluminum threads, as the 4-40 thread form is fine-pitched and susceptible to thread stripping if excess force is applied. Follow applicable facility or equipment lockout-tagout procedures before beginning board-level service work.
