These ARP stainless steel hex bolts are sized 5/16-18 x 2.250 in and are sold as standard fasteners for fabrication and mechanical assembly. The stainless construction provides corrosion resistance compared with plain steel bolts, and the 5/16-18 thread and 2.250 in length match common torque and fastening needs where that size is specified.
