Stainless Steel Hex Bolts And Nuts

Hexagonal bolts or Stainless Steel Hex Bolts are a six sided industry standard for fasteners with forged heads. Per usual SS hex head bolts can be used for many various applications which include fastening steel, wood, or other construction materials.

SS Hex Bolts And Nuts

These SS Hex Bolts And Nuts are used in projects for structural or architectural construction such as bridges, docks, highway structures, and buildings. Generally, those Hex bolts which are produced with forged heads are also used commonly as a headed anchor bolt. Usually, construction and architectural applications require alloy grades which are resistant to oxidative corrosion which is why various grades of SS heavy hex bolts are chosen for this application. For instance, dual certified grade 304H/ 304 SS hex bolts are able to resist oxidation due to a higher content of chromium. This is because of a phenomenon referred to as passivation which occurs on the surface of SS 304 hex bolt, which in turn protects the alloy from getting corroded by the atmosphere. Very often structural applications require their components to be welded together. That’s where 316l hex bolts step in! Alloys with low carbon content are specially designed to assist with welding needs. Hence, this modification in their chemistry. While regular grades like 316 ss hex bolts can be welded, it’s derivative ie. grade 316L creates a potency to welding minus the decay caused by corrosion.
