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.
ZXL™ No Red Rust
- 5/16” Cupped HWH is manufactured from a strong ZAMAC zinc-aluminum alloy, The head is molded. It is not a cap. The molded head encapsulates the EPDM washer, which fits neatly and conforms to the inside of the mold.
- Head and washer face carry a 40 year warranty against red rust.
- ZXL is proudly molded in the USA.
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.

The combination of the Micro-Bit point & transition thread from fine to coarse generates superior drill speed in metal & holding strength in wood substrates.
The Zinc-Aluminum alloy HWH prevents red rust from ever starting. ST Fastening Systems spring retainer sockets are designed to allow for the added thickness of the powder coat and are recommended.
