Electro Hardware MM1358M09-MSC Hex Standoff 6-32 1in Ss

Product Description

The ELECTRO HARDWARE MM1358M09-MSC is a male-male hex circuit board standoff machined from 18-8 grade 303 stainless steel with a passivated finish. It accepts a 6-32 threaded fastener on both ends and measures 1 inch overall length with a 3/16 inch width across flats. The hex body shape allows for wrench or nut driver installation, keeping boards securely spaced and aligned during assembly. It meets QQ-S-763 fastener standards. Electronics assemblers, PCB technicians, and control board service technicians install these standoffs in panel builds, enclosure assemblies, and circuit board mounting applications where corrosion resistance and dimensional accuracy matter.

This standoff is suited for use in residential and commercial electronic control panel assemblies, enclosure builds, and PCB mounting configurations. The passivated stainless steel construction is appropriate for environments where mild corrosion resistance is required. The 6-32 thread size is one of the most common in PCB and control board mounting, making this part a fit for a wide range of standard circuit board spacing applications across HVAC control boards, electrical enclosures, and similar assemblies.

Key Features

• Male-male thread configuration on both ends accepts 6-32 fasteners for through-board stacking
• 1 inch overall length with 1 inch body length provides consistent board-to-panel spacing
• Hex body shape, 3/16 inch width across flats, compatible with standard nut drivers and wrenches
• 18-8 grade 303 stainless steel with passivated finish resists oxidation and corrosion
• Meets QQ-S-763 fastener standard for dimensional and material compliance
• Length tolerance of -0.005 to 0.005 inch ensures consistent fitment in precision assemblies

Compatibility

Designed as a standard 6-32 male-male hex standoff for use in circuit board and electronic enclosure assemblies requiring a 1 inch OAL stainless steel spacer with hex drive geometry.

Installation Notes

Install using a nut driver or open-end wrench sized for a 3/16 inch hex flat. De-energize all control boards and panels before installing or removing standoffs. Avoid over-torquing, as stainless fasteners are subject to galling — apply consistent, moderate torque and consider anti-seize if repeated removal is expected. Follow applicable enclosure and panel assembly guidelines per NEC or equipment manufacturer specifications.
