Hex Nut Grade 8 Zinc Yellow

Zoro Select hex nuts supply a Grade 8 steel fastener with a yellow zinc finish for high-strength inch-thread assemblies. The UNC 7/16"-14 thread and 11/16 in hex width suit standard wrenching. Each small pack contains 50 pieces for production or maintenance use.

Build integration with standard inch hardware

Right-hand UNC threads mate with matching bolts or studs without special tools. The 3/8 in hex height keeps the profile low inside fixtures. Rockwell hardness between C33 and C39 resists stripping under torque. ASME B 18.2.2 dimensional control ensures interchangeability across suppliers.

Upgrade from lower-grade or plain-finish nuts

Grade 8 strength replaces Grade 5 or ungraded hardware where higher clamp load is required. Yellow zinc coating improves corrosion resistance over bare steel in automotive and industrial environments. Not suited for metric-thread applications or locations needing stainless or plated alloy alternatives.

Questions about this item

What is the maximum Rockwell hardness of the Grade 8 steel?

The nuts are heat-treated to a Rockwell C33–C39 range, giving high tensile strength for demanding fastening jobs.

How much heat does the zinc-yellow finish add during continuous tightening?

The coating is a thin conversion layer; it does not generate measurable heat when the nut is torqued all day.

Which wrench size fits the 11/16 in hex width?

A standard 11/16 in open-end or socket wrench engages the hex flats directly.
