Washer, #10 Flat

Zinc plating is holding up nicely so far, no rust after a week of sitting on my bench in the garage. The #10 sizing fits my bolts exactly, and they’re flat enough to sit flush in the counterbore I drilled. Just what I needed for a quick assembly job.

Finally got around to using these #10 flat washers on a bench jig, and the zinc plating is holding up nicely without any rust after a few days of handling. The steel feels solid, and the 1/4-inch inner diameter fits the bolts exactly as expected.

The zinc plating on these #10 flat washers is smooth and even, no burrs or rough edges that would snag during assembly. They seat flush on the bench top and hold torque without deforming, exactly what I need for standard machining work.
