Hillman 5/16 in. X 3-1/2 in. L Hex Stainless Steel Lag Screw 25 pk

Stainless steel hex lag screws offer a higher level of corrosion resistance, and is great for any outdoor project.

Its stainless steel finish provides anti-corrosive properties and makes it slightly stronger than regular (un-hardened) steel bolts.
