Electro Hardware MP1037M09F16M3 Female Hex Standoff M3x0.5

Product Description

The ELECTRO HARDWARE MP1037M09F16M3 is a female hex circuit board standoff designed to create precise spacing between PCBs and mounting surfaces in electronic assemblies. Manufactured from 303 stainless steel with a plain bright finish, this standoff meets QQ-S-763 material standards. The M3 x 0.5 internal thread accepts a standard M3 fastener, with a thread depth of 6.4 mm (approximately 0.252 inches). Overall length measures 19 mm (approximately 0.748 inches) with a hexagonal body shape and 6 mm (approximately 0.236 inches) width across flats. The partial thread design and length tolerance of -0.13 to 0.13 mm make this standoff suited for applications requiring dimensional consistency and corrosion resistance.

This standoff is used in electronic control panel assembly, industrial PCB mounting, and circuit board stacking applications across HVAC control systems, electrical enclosures, and commercial electronics. It is installed by electricians, controls technicians, and electronics assemblers wherever secure, repeatable PCB standoff spacing is required. The stainless steel construction makes it appropriate for environments where mild corrosion resistance is a factor. Minimum order quantity is 10 units per order.

Key Features

• Female M3 x 0.5 internal thread with 6.4 mm thread depth for positive fastener engagement
• 303 stainless steel construction meets QQ-S-763 material standard
• Hexagonal body profile, 6 mm width across flats, allows wrench tightening during installation
• Plain bright finish with no coating — compatible with grounding or continuity requirements where bare metal contact is needed
• Tight length tolerance of -0.13 to 0.13 mm supports consistent board-to-board or board-to-chassis spacing
• Metric measurement system — integrates directly with M3 hardware in metric-specified assemblies

Compatibility

Designed as an OEM-style metric hex standoff for use with M3 x 0.5 fasteners in circuit board mounting and PCB stacking applications. Compatible with assemblies requiring a 19 mm overall length standoff with a 6 mm hex body.

Installation Notes

De-energize and discharge any circuit boards or assemblies before installing or removing standoffs. A wrench sized for 6 mm width across flats should be used to seat the standoff without overtightening, which can stress PCB mounting holes. Follow applicable assembly drawings and torque guidelines provided by the board or enclosure manufacturer. Installation is typically performed by electronics assemblers or licensed electricians working within control panel or PCB assembly workflows.
