Hillman 3/8 in. X 6 in. L Hex Stainless Steel Lag Screw 25 pk

Bolts are made of stainless steel 18-8 which is an alloy of steel with high corrosion resistance and is great for any outdoor project. Common applications include retaining walls, deck frames and outdoor play equipment. This screw has coarse threads with a hexagonal drive. Its stainless steel finish provides anti-corrosive properties and makes it slightly stronger than regular (un-hardened) steel bolts.
