Exactly As Described

Extended length was necessary for my thick wall panels. Works great and the zinc plating looks durable.

Perfect Length

These screws fit my 86-type boxes perfectly. No more struggling with short screws that barely catch the threads.

Good Value

Solid screws for the price. One head stripped slightly during installation but overall good quality for the batch.

Heads Could Be Better

They work but the Phillips head is a bit shallow. Use a good driver to avoid stripping the screw head.
