#10 x 2" self-drilling Woodbinder screw for fastening steel roofing and siding panels to wood framing through underlayment, strapping, or thin foam. The Micro-Bit drill point cuts through panel metal without punching, and the fine-to-coarse thread transition pulls the head down for a flush, weathertight seat against a vulcanized EPDM-on-steel washer that seals reliably even when driven at an angle.

• Hex washer head, #10 gauge x 2" length, 1/4" drive socket
• Self-drilling Micro-Bit point eliminates need to pre-punch metal
• Fine-to-coarse thread transition for superior holding in pine, fir, and SPF framing
• UV-resistant EPDM rubber vulcanized to G-90 steel-backed sealing washer
• V-neck head design resists twist-off under driver torque
• 2.5 mil powder coat over zinc-plated and chromate-sealed carbon steel
• 250 screws per pack

Best for: metal roofing installed over a layer of 1x furring strapping or thin closed-cell foam underlayment on top of sheathing, where the extra length is needed to reach solid wood after passing through the spacer layer.

Tip: Keep a 7/16" magnetic nut driver dedicated to this fastener line -- a worn or undersized socket cams off the V-neck head and is the leading cause of stripped heads on long Woodbinder runs.
