SEALTITE KWIKSEAL WOODBINDER SCREW - #10 x 1-1/2", 250-PACK#10 x 1-1/2" self-drilling Woodbinder screw for fastening steel roofing and siding panels to wood sheathing or framing. 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 1-1/2" 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: standard residential metal roofs over OSB or plywood sheathing -- the 1-1/2" length is rated by ST Fastening to fully penetrate sheeting and grip the rafter or truss below.
Tip: On overlapping panel ribs, pre-position the screw at the rib peak with the panel firmly seated; driving the screw cold against a lifted panel is the most common cause of stripped washers on this fastener line.
