MAXX™ SteelBinder®

Fastener designed to attach metal roof and sidewall panels used in pre-engineered metal building applications.

#12 Diameter 5/16” Cupped HWH self-drilling fastener easily penetrates steel up to .210” in thickness with no “point walking.” 1/4” Stitch will securely fasten panel sidelaps up to 18 ga. panel thickness with no strip-out when installed correctly.

Cupped head & washer encapsulate EPDM rubber washer & provide a secure seal even when driven at an angle.

Applications

Metal to metal fastener designed to attach steel roofing & siding used in pre-engineered metal building applications.

NOTES:

HRS (Hot Rolled Steel)
Pull over values calculated with EPDM rubber washer assembled to cupped head screw with .555” washer face.
All strength values shown are ultimate values, expressed in LBS. Apply an appropriate safety factor to obtain design limits.

ALL UNPAINTED MAXX STEELBINDER® FASTENERS COME STANDARD WITH DURASEAL® PLUS ENHANCED CORROSION RESISTANCE COATING.

FOR PROPER INSTALLATION, THE USE OF IMPACT DRIVERS ARE NOT RECOMMENDED FOR POWDER COATED OR ANY WET PAINTED FASTENER.

PULLOUT & PULLOVER VALUES ARE DETERMINED IN THE ST FASTENING SYSTEMS ENGINEERING LABORATORY USING STEEL PANELS/FRAMING & WOOD DENSITIES WHOSE STRUCTURAL PROPERTIES ARE FOUND IN PRESENT DAY PRODUCTS.

2.5 mil of computer controlled powder coat is applied over zinc plating and chromate sealer.

Unique polyester powder formulation resists harmful UV rays and chemical breakdown.

Automated process ensures a consistent color match from batch to batch.

POWDERFUL is completely free of volatile organic compounds (VOC), and is entirely recyclable.

There are 35 standard colors that match high volume metal panel paint colors.

No Point Walking–Effortless quick penetration-Easy Multi-Layer Penetration-Drilling capacity to .210”

Advanced forging process technology – Sharp drill edges consistently cut the metal, eliminating slow or dropped screws and pigtails that can embed themselves in the rubber washer.

1/4ʺ Stitch will securely fasten panel sidelaps up to 18 ga. panel thickness with no strip-out when installed correctly
