ASME B18.6.3 Zinc Plated Steel Machine Screw Hex Nut, #4-40

ASME B18.6.3 Zinc Plated Steel Machine Screw Hex Nut, #4-40 Thread Size, 3/32" Width Across Flats, 1/4" Thick (Pack of 100)
- Hex Nuts are appropriate for use in low-strength assemblies
- Zinc Plated Steel fasteners are suitable where strength and corrosion resistance are primary considerations
- Drive system is a hexagon-shaped head
- Coarse threads are better for brittle materials, and will assemble and disassemble more quickly than fine threads
- Ensure a lasting hold for any project
Most often used on machine screws and threaded rod, these general purpose nuts are for low-strength assemblies. Hex Nuts have flat tops with chamfered corners; bottoms may be flat or chamfered. Hex drive systems are driven with a wrench.

Steels are designated by a 4 number SAE Steel grade.Â The first two digits indicate the primary materials used to form the steel.Â The last 2 digits identify the percentage of carbon for the alloy (in hundredths).Â The steel used in these fasteners has a tensile strength ranging from 100,000 to 150,000 psi (pounds per square inch).Â Zinc Plating helps to prevent corrosion.

A threaded fastener's size name includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine. Coarse threads are better when working with brittle materials; they are sturdier and are easier to thread and unthread compared to fine. Coarse threading also allows for thicker coatings and platings.
