Concrete dowel screws feature a dual-thread design with machine threading on one end and concrete or masonry screw threading on the other. This allows a single fastener to anchor securely into concrete while providing a threaded stud for attaching components with nuts or other hardware.
They are commonly used in structural framing, solar installations, and applications where strong, vibration-resistant anchoring is required.
A4 / 316 Stainless Steel fasteners are “marine grade” corrosion resistant; suitable for outdoor and salt water environments. A4 fasteners also offer increased resistance to chemicals when compared with A2 stainless fasteners.
