16" Lag Screw

Got some hard to find 16" lag screws and it was very quickly received when I needed them fast. The price was decent too.

Received on time!

Ordered these late, and under pressure, but received on time! Note that you need a 3/4 socket and it's not typical in most sets.

This item worked well for its intended purpose of mounting and securing a wood mantle.
