غسالات مسطحة مقاس #5 × 9/16" قطر خارجي | سماكة .058" | فولاذ مطلي بالزنك (200 / عبوة)

Just threw these on a few bolts to secure a shelf bracket, and the .058 inch thickness feels solid under the nut without any flex. The zinc coating is even and clean, no rough edges to snag on anything.

Zinc plating looks clean and even, no flaking or rough edges straight out of the package. These have held up fine under a few outdoor fasteners so far, and the 200-count box means I've got plenty of spares for future jobs.

The sizing is spot on for my 5/16" bolts, and the zinc coating seems thick enough to resist rust. I appreciate that they're a solid .058" thick—they don't bend under heavy torque like thinner washers sometimes do. For the price, getting 200 of these is a steal.
