MIDWEST FASTENER CORP 77188 Flange Nut M10-1.50 Steel Class 10 Black Phosphate

MIDWEST FASTENER Flange Nut M10-1.50

This MIDWEST FASTENER CORP 77188 flange nut is a Class 10 steel fastener with a black phosphate finish. The integrated flange acts as a non-spinning washer to distribute clamping pressure across the secured part. It reduces the chance of surface damage and helps prevent loosening on uneven fastening surfaces. The thread specification is M10 with a 1.50 pitch.

Suits high-strength metric assemblies needing

Builders assembling structural joints or automotive components where a separate washer is impractical will benefit from the integrated flange design. The Class 10 rating supports high preload requirements in critical connections. Buyers who need a different thread diameter, pitch, or a lower property class for lighter loads should look at other fastener options. Those requiring stainless steel or a different drive style must choose another product.

The deciding spec is the M10-1.50 thread

Matching the exact M10 diameter and 1.50 pitch to the mating bolt or stud is the single factor that determines whether this nut fits the application. The Class 10 property class defines the proof load and hardness required for the joint design. The black phosphate coating provides a baseline level of corrosion resistance for the operating environment. Verify these three parameters against the assembly drawing before ordering.
