Specifications
1-1/4" x 4" ASTM F3125 A325 Type 1 Heavy Hex Structural Bolt - Plain
When pairing a nut with a hex bolt, the material and finish must match. If these do not match, the nut will not fit the bolt.
These 1-1/4" diameter Conquest A325 Type 1 Structural Bolts are engineered for steel-to-steel connections in bridge building, structural framing, and infrastructure projects. Their heavy hex design maximizes torque and load retention, helping maintain strong, stable assemblies under dynamic loads.
ASTM F3125 Compliant 1-1/4" Hex Bolts for Structural Applications
Manufactured to meet ASTM F3125 (A325) standards, these structural bolts provide the strength and consistency demanded by contractors and engineers. The plain finish allows for installation in non-corrosive, controlled environments where additional coatings are not required.
