FeatureS

Powderful™ Coating System

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.

KS V-NECK™ Head Design

HWH with V-neck design adds strength to prevent head twist off under extreme torque.
UV resistant EPDM rubber is vulcanized to a G-90 steel backed washer to provide maximum sealing ability, which prevents leaks, even when drilled at an angle.
High tensile steel washer provides excellent pullover strength.
ST MAGNETIC SOCKETS are designed with an advanced forging process to fit the painted fastener securely, which helps to prevent fastener wobble upon installation.

KS LO-ROOT™ Thread Design

Fastener thread transitions from fine to coarse. The low root design provides excellent pullout strength versus traditional or HI-LO thread forms.

MICRO-BIT® Point Design

Drill point design consistently penetrates metal panels, which 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.

ALL UNPAINTED WOODBINDER MB 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.

THE MB MICRO-BIT POINT MAY GENERATE SMALL METAL SHAVINGS UPON INSTALLATION. IT IS RECOMMENDED TO CLEAN/SWEEP THE METAL PANELS AFTER INSTALLATION TO PREVENT PREMATURE RUST SPECKS.

Available for powder coated fasteners.

Hex Washer Head with EPDM rubber washer provides a watertight seal on roof applications. ST Fastening Systems sockets are designed to allow for the added thickness of the powder coat.

The combination of the Micro-Bit point & transition thread from fine to coarse generates superior drill speed in metal & holding strength in wood substrates.
