The .275" x 4-1/2" Conquest Structural Screw is engineered for heavy structural wood connections requiring deeper embedment and superior clamping strength.

The T-30 star drive ensures strong bit engagement under high torque, helping contractors maintain control during installation.
Note: ICC-ES code approved for structural wood applications.
With its extended 4-1/2" length and robust .275" diameter, this structural screw penetrates deeply into dimensional lumber and engineered wood, creating secure load-bearing connections. The aggressive self-tapping thread design reduces installation time while maintaining dependable holding power in dense materials.
