Electro Hardware MM1309M09MSC-1 Hex Standoff 6-32 1/4 in

Product Description

The ELECTRO HARDWARE MM1309M09MSC-1 is a male-male hex circuit board standoff designed for securing printed circuit boards at a fixed distance from a mating surface or stacking boards within an enclosure. It features a 6-32 threaded connection on both ends, an overall length of 0.25 inches, and a hex body shape measuring 3/16 inches across the flats. Constructed from Grade 18-8 303 stainless steel with a passivated finish per QQ-S-763, this standoff resists corrosion and maintains dimensional stability in demanding environments. It is installed by electronics assembly technicians, electricians, and field service professionals working on control boards and panel assemblies.

This standoff is used in residential and commercial control panel assemblies, electrical enclosures, and electronic equipment where a compact, low-profile board-mounting solution is required. Its male-male thread configuration allows it to thread directly into a tapped hole on one side while accepting a nut or female standoff on the opposite end. The 0.25-inch overall length suits tight-clearance PCB mounting situations where minimal board-to-surface separation is needed.

Key Features

• Male-male 6-32 thread on both ends for direct board-to-surface or board-to-board mounting
• 0.25 inch overall length with a body length of 0.25 inches for compact, low-profile installations
• Hex body shape, 3/16 inches width across flats, allows standard wrench or nut-driver engagement
• Grade 18-8 303 stainless steel construction for corrosion resistance and mechanical durability
• Passivated finish meets QQ-S-763 fastener standard
• Length tolerance of -0.005 to 0.005 inches for consistent, repeatable board spacing

Compatibility

Designed as an OEM-style replacement or new-installation fastener for circuit board assemblies requiring a 6-32 male-male hex standoff with a 0.25 inch overall length in inch-measurement systems.

Installation Notes

Installation is performed by qualified electronics assembly technicians or licensed electricians. Always de-energize and lock out the equipment before servicing any circuit board or control panel. Use a correctly sized wrench or nut driver on the hex body to avoid rounding the flats. Follow applicable NEC guidelines and equipment manufacturer torque recommendations when fastening control boards inside electrical enclosures.
