Zoro Select MPB655 Hex Nuts
These Zoro Select MPB655 hex nuts are standard fasteners for general-purpose mechanical assembly. The chrome-plated steel construction provides corrosion resistance for indoor and outdoor applications. Each pack contains 50 pieces to support volume requirements.
Sustained load behaviour
Grade 2 steel meets SAE J995 material quality standards for consistent tensile performance under continuous clamping force. The right-hand fine thread with 2B fit maintains joint integrity through vibration and thermal cycling. Chrome plating resists surface degradation during extended service.
Thread specification decides fit
The 5/16-24 fine thread pitch determines compatibility with matching bolts and tapped holes. A 1/2 in hex width and 17/64 in height define the tool engagement and stack height. ASME B 18.2.2 dimensional standards ensure interchangeability across suppliers.

Questions about this item
How much heat does the 5/16-24 Grade 2 chrome steel hex nut generate when installed all day?
The nut is a passive fastener with no moving parts or electrical load, so it produces no measurable heat during continuous use.
What tools or components must I already own for the 1/2 in hex width nuts to work?
You need a 1/2 in wrench or socket and a matching 5/16-24 fine-thread bolt or stud to engage the 2B thread fit.
Will the 17/64 in height hex nuts thread correctly onto older SAE J995 Grade 2 bolts?
Yes, they share the same Grade 2 material standard and 5/16-24 thread specification, so they engage fully with existing hardware.
