Characteristics of A193 B7 Bolts

Structural hex bolts feature larger heads than standard hex bolts. They are 1/8" wider than standard hex heads of the same diameter. This allows heavy hex bolts to bear against flanges and support work in high-pressure applications. The heavy hex heads are also thicker than standard hex bolts, which increases their strength and hold. They have high tensile strength and superior threading for secure connections. They are available in different materials designed for varying finishes and levels of corrosion resistance.

A193 B7 Bolt Advantages at a Glance

  • Larger, thicker heads than standard hex bolts
  • High tensile strength & yield strength
  • Good fatigue resistance
  • Good resistance to galling & seizing
  • Available in a variety of sizes and finishes
