## Description

These bolts are coarse threaded and made of quality "Marine Grade" type 316 stainless steel and are suited for resisting rust & corrosion in most environments. (For chemical, salt water or coastal environments type 316 stainless is a must! Standard 304/18-8 will not hold up!) These are standard six sided external hex heads and depending on length can be fully or partially threaded. Length is measured from underneath the head.

Review: True 316 Stainless Steel - 316 stainless is my go to finish for anything that you need to use outdoors. Don’t be fooled, 307 stainless will rust. I live on a lake and these are a must. I always purchase from Marine Supply.
Review: Strong bolts for what i needed - Needless to say these bolts helped hold down a Ducati to two pieces of attic board and an 80 dollar motorcycle chock from desertcart and I only used hand tools to crank down the bolts
