  • 4-40 X 1/2 Flat Head Cap Screw Alloy Steel Black Oxide USA: Has a minimum single shear strength of 950 lbs and a minimum tensile strength of 880 lbs
"The shear strength of a 1/8 inch stainless steel rivet with a steel body can range from 420–550 lbs."

I postulate that a 4-40 machine screw in an MK-10000-04 nutplate is structurally equivalent to a 1/8 SS pull rivet.

Context: Attaching a Sonex instrument panel to glare shield.

Discuss. I already know what Kerry would say....<grinning>.
