Good value

Quality is decent for the price. One screw had a slightly stripped head but the rest were fine.

Perfect for deep mounts

These extra-long screws were exactly what I needed for my switch plate installation. The zinc plating looks durable.

Solid hardware

Use these for machinery assembly. They hold tight but be careful not to over-torque.
