Small Wrench Hex Nuts / Coarse + Fine Thread are general purpose nuts for tight clearance applications where a small wrench is required.

Class 8 metric hex nuts provide a medium strength, high tensile fastening solution. Commonly paired with Class 8.8 bolts and screws.

Coarse and Fine Thread Diameter sizes are specified / written differently. Coarse thread bolt sizes are commonly noted without the pitch.

Example: M10X1.5 is a coarse thread pitch, commonly identified as M10.   M10X1.25 is a fine thread pitch, identified as M10X1.25 Fine.
