Roofing Fasteners By Fasteners Plus

• [COATED SCREWS] 2.5 mil of computer controlled powder coating apllied over zinc plating and chromate sealer. Resists harmful UV rays and chemical breakdown. Completely free of volatile organic compounds (VOC), and is entirely recyclable
• [ZXL NO RUST] 5/16" Cupped HWH is manufactured from a strong ZAMAC zinc-aluminum alloy. Molded Head encapsulates the EPDM washer, which fits neatly and conforms to the inside of the mold
• [KS LO-ROOT THREAD DESIGN] Fastener thread transitions from fine to coase. The low root design provides excellent pullout strength versus traditional or HI-LO thread forms
• [MICRO-BIT POINT DESIGN] Drill point design consistently penetrades metal panels, eliminates the need to "punch" the metal panels with a sharp point to start the drilling process. MB point is excellent for penetrating multiple thicknesses of steel often found on ridge cap or trim applications
