SELF-DRILLING MICRO-BIT POINT - Galvanized pole barn screws easily penetrate high-strength metal roofing and siding sheets while minimizing metal "pigtails". Provides a superior drilling speed that reduces slow drilling for consistent performance. ZXL NO RED RUST HEX HEAD - 5/16" Cupped HWH with a molded ZAMAC Zinc-Aluminum alloy provides manufacturer lifetime protection against red rust on the head and washer. INSTALLATION TYPE - #10 Carbon steel fasteners designed to attached to steel roofing and siding in post-frame and residential applications. Resists harmful UV rays and chemical breakdown. XTREME HOLD THREAD DESIGN - KS Lo-Root thread transitions from fine to coarse to generate superior holding strength in various wood substrates. The low root design provides excellent pullout strength versus traditional or HI-LO thread forms. POWDERFUL CORROSION DEFENSE - Fade-Resistant Powderful coating outperforms wet paint and continues to match panels for decades, helping to retain a structure's value. The Sealtite ST Fastening ZXL Woodbinder screws are self-drilling screws designed to attach metal roofing and siding to wood purlins on post-frame and residential metal roof applications. Coated screws feature a tough 2.5 mils of powder coating that will not chalk or fade due to the UV inhibitor in all colored coatings. 5/16" cupped HWH with a molded ZAMAC 5 Zinc-Aluminum alloy provides lifetime protection against red rust on the head an washer. The ZAMAC 5 alloy offers more strength than the common ZAMAC 3 alloy. The washer face design helps capture the rubber EPDM washer even when driven at an angle. Threads transition from fine to coarse, generating superior holding strength in various wood substrates. The sharp point with pronounced lead thread consistently drills high-tensile 29 & 26-gauge steel with no "point walking."
