The 8 Best security Lag Screws (2023 reviews)

It is not much fun when you're high up on a ladder where all your neighbors can judge you. They HOLD those 2 x 6’s great, and look really nice. They are high quality screws. The threads engage the substrate solidly without slipping or tearing, and the socket engages the driver without failing under normal driving forces, so the head looks decent after the screw has been driven.

These are a much larger size than normal deck screws and you need to predrill to use properly. It is easy to install with an impact driver, and can be screwed in directly without pilot holes or splitting the wood. This lag screw is strong and secures easily and quickly.

Why We Like This:

Strong, great looking no strip head
Very nice screws with the bit supplied
Excellent lag screw for soft wood
Capable of smiting down any piece of lumber in their path
