"Lubricated" means coated with a lubricant such as engine oil, or fasteners with phosphate and oil coatings.
b
"Dry" means plain or zinc plated without any lubrication.

Shear bolts are designed to fail under predetermined loads. Always
Tighten plastic insert or crimped steel-type lock nuts to approximately
replace shear bolts with identical property class.
50 percent of the dry torque shown in the chart, applied to the nut,
not to the bolt head. Tighten toothed or serrated-type lock nuts to the
full torque value.
Fasteners should be replaced with the same or higher property class.
If higher property class fasteners are used, these should only be
tightened to the strength of the original.
