Electro Hardware 1467M09F16-440 Hex Standoff 4-40

Product Description

The ELECTRO HARDWARE 1467M09F16-440 is a male-female hex circuit board standoff used to space and secure printed circuit boards within electronic enclosures and control assemblies. It features a 4-40 thread size, an overall length of 1.6875 inches, and a hex body width across flats of 0.25 inches. Constructed from 18-8 and Grade 303 stainless steel with an anodized finish, it meets the QQ-S-763 fastener standard. Electronics assemblers and field technicians install this standoff to maintain precise board-to-board or board-to-chassis spacing while providing a secure threaded connection point.

This standoff is suited for use in control boards, relay panels, motor drive assemblies, and similar electronics found in HVAC control systems, electrical enclosures, and industrial equipment. The male end threads into a chassis or lower board, while the female end accepts a machine screw to capture the upper board. The hex body shape allows wrench engagement for torque-controlled installation. It is appropriate for both original assembly and field replacement applications where a 4-40 threaded male-female standoff is required.

Compatibility

Designed as a standard 4-40 male-female hex standoff for use in circuit board mounting applications requiring an overall length of 1.6875 inches and a 0.25-inch hex body.

Installation Notes

Installation is typically performed by electronics assemblers or licensed electricians working on control panel assemblies. Power down and de-energize the enclosure fully before removing or installing any circuit board hardware. Use a hex wrench or nut driver sized to the 0.25-inch width across flats to seat the standoff without over-driving. Follow applicable NEC guidelines when working inside electrical enclosures.
