1/2" x 8" (25 Pack) Galvanized Carriage Bolt Kit Grade 307A, Includes 1/2" USS Flat Washers (25 pcs) and 1/2"-13 Hex Nuts (25 pcs), Hot Dip Galvanized for Exterior Use by Fastener Depot, LLC

These worked just fine for me bolting together 2x6.

This product was ideal for my deck project. I needed a large quantity and the 25 pack with nuts and washers cost less and saved me time when considering that I would have had to individually pick bolts, nuts and washers at my local home store.

Came as expected and didn't have to go in the store.

Great for decks

Great product, well coated
