Our 316 Stainless Steel Lag Screws, or Lag Bolts as many call them have coarse threads meant to fasten timbers similar to a smaller wood screw. As always, our our curated to be top quality, and are far superior than their 304 Stainless counterparts when it comes to corrosion resistance.
In shorter lengths these lag bolts are fully threaded, but only partially threaded as their lengths get longer. If thread length is important for you and your project you can check the exact thread length of every lag bolt we sell in the handy chart below.
