Heavy-duty 20-inch industrial fastener screws designed for structural and mechanical assembly applications in construction, infrastructure, and heavy equipment manufacturing.

These large-format screws are precision-machined from high-grade carbon steel or stainless steel and feature a hex head or square drive for high-torque installation using pneumatic or hydraulic torque tools.

The full-thread or partial-thread configuration options accommodate varying grip length requirements, while the coarse pitch ensures rapid engagement in structural steel and timber connections.
