SPAX 1/2" x 5" Exterior Hex Head Structural Wood Lag Screws Powerlags Hex (100 EA) Bulk Pail Bit Included Heavy Duty Rust Resistant

These lag screws scream quality, as in ISO 9001:2015 Certified. Everything about them is just perfect. From the self-tapping serrated thread to the shape of the screw head. I used them to attach 2x12 ledgers for a deck, and can not be more happy about them.

Sharp serrated threads cut well without splitting the wood.

great for wood, no pre-drilling needed
