STO - 148 - U-BOLTS
 
U-BOLTS GRADES
  • The choice of materials is determined by the required SAE Grade and the size of the material and its harden ability. We produce U-Bolts in SAE Grades 2, 3, 4 and 8.
  • Grade 2 U-Bolts are produced from cold drawn or hot rolled low carbon steels.
  • Grade 3-UBolts are produced from cold drawn medium carbon steels.
  • Grade 5 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.
