U-Bolt-It manufacturers and distributes a variety of carbon steel fasteners including u-bolts, studs, carriage bolts, and more. Carbon steel is a popular material for fasteners due to its good tensile strength and ability to bear loads. It responds well to heat-treatments with minimal work hardening and brittleness. It is easy to machine and can meet the tight tolerances required for threading and fastener configurations. Carbon steel is also an economic metal.

Carbon steel is categorized by the amount of carbon in the alloy, which impacts the properties of the steel. Low carbon steel, with 0.05-0.3% carbon, is ductile and malleable. It has low tensile strength and can be hardened through carbonizing. It is the least expense of the carbon steel alloys.

Medium carbon steel has 0.3-0.59% carbon, which provides the alloy with increased strength and good ware resistance. It is easy to machine and is used for forged and automotive parts.

High carbon steel and ultra-high carbon steel is very strong and is used for springs and high-strength products. These alloys can be tempered to very high hardness without brittleness, and are used for very high wear applications. These alloys have carbon from 0.6-0.99% for high carbon steel and 1.0-2.0% for ultra-high carbon steel.

Good Afternoon Sir, I received your letter in the mail today. I was ecstatic to receive and read it. It was wonderful doing business with you and your company. The first initial response was great, they got my order in pronto. Even after my mistake of ordering the wrong size of bolts, they were very accommodating and understanding and worked with me to get the right ones ordered. I will definitely keep you and your company in mind when someone is needing your line of product. I appreciate and thank you for all your help. P.s. Thank you for the glasses clothe, with having a 5 almost 6 year old my phone is in need of constant cleaning. It will be well used.

– W.
