HEX BOLTS

Description:

Hex bolts from ITA Fasteners are mostly used in repair and construction work. As the name implies, they have a hexagonal head and come with machine threads for a firm and rough handling. They come in a wide range of different hex bolt sizes for custom applications depending on its dimensional requirements. These Hex Bolts come in the anti-corrosion stainless steel, alloy steel and carbon steel materials which ensures that the structure doesn’t weaken because of rust. Depending on the length of the bolt, it can come with standard threading or full threading.

Since it is made out of such strong materials, these high quality grade 8.8 bolts are often used in high-temperature environments like automotive parts assembly. These Hex Bolts can also be used in marine and coastal operations due to its anti-corrosion property. We ensure that all our products are durable and high strength components which can only enhance your work's credibility. If you require stainless steel hex bolts, hex head bolts or hex bolts in large orders, get in touch with us to get a quote.
