SAE GRADES
The choice of materials is determined by the required SAE Grade and the size of the material and its hardenability. We produce u-bolts in SAE Grades 2, 3, 5 and 8.
Grade 2 U-Bolts are produced from cold drawn or hot rolled low carbon steels.
Grade 3 U-Bolts are produced from cold drawn medium carbon steels.
Grade 5 U-Bolts are produced from either medium carbon steel or a carbon manganese alloy steel.
Grade 8 U-Bolts are produced from a carbon manganese alloy steel.
All Grade 5 and 8 u-bolts are heat treated.
To produce our SAE Grade 5 and 8 U-Bolts we heat treat them to produce the mechanical properties specified under the SAE grading.
