Electro Hardware MP1021M19F16M3 Female Hex Standoff M3

Product Description

The ELECTRO HARDWARE MP1021M19F16M3 is a female hex circuit board standoff designed to create precise, secure spacing between PCBs and mounting surfaces in electronic assemblies. Manufactured from nylon with a plain (bright/uncoated) finish, this standoff accepts M3 x 0.5 metric threading and provides an overall length of 11 mm (approximately 0.43 inches) with a fully threaded depth of 11 mm throughout the entire body. The hexagonal body measures 6 mm (approximately 0.24 inches) across the flats, allowing standard hex tooling for installation. It meets MIL-P-17091B fastener standards and carries a tensile strength rating of 16,500 psi, making it suitable for demanding electronic assemblies where dimensional precision and material consistency matter.

This standoff is used in electronics manufacturing, control board assembly, and field service applications where PCBs must be mounted with controlled standoff height. The nylon construction makes it well suited for environments where electrical isolation between the board and chassis is required. Typical installations include HVAC control boards, industrial electronics enclosures, and any electronic panel requiring a non-conductive, metric-threaded spacer. Installation is performed by electronics assemblers and field technicians working on low-voltage control systems.

Key Features

• Female M3 x 0.5 metric threading, fully threaded through the 11 mm body length
• Nylon construction provides electrical isolation and corrosion resistance
• Hex body (6 mm across flats) allows wrench or hex driver installation for consistent torque
• Length tolerance of -0.13 mm to +0.13 mm ensures precise PCB standoff height
• Meets MIL-P-17091B fastener standard with a tensile strength of 16,500 psi
• Plain (bright/uncoated) finish - no plating to introduce conductivity or dimensional variation

Compatibility

Designed as a metric M3 x 0.5 female hex standoff for use in circuit board mounting applications requiring a non-conductive nylon spacer conforming to MIL-P-17091B standards.

Installation Notes

Power down and de-energize all circuits before installing or removing circuit board standoffs. A hex driver or wrench sized to 6 mm across flats should be used to seat the standoff without over-stressing the nylon body. Avoid applying excessive force - nylon fasteners are subject to deformation under overtorque. Verify thread engagement on both the standoff and the mating fastener before applying board assemblies.
