Kwikseal MB Illustration Logo-08

  • Designed to fasten steel roofing to wood purlins used in post-frame construction, & plywood or OSB used in residential construction.
  • 5/16 cupped HWH with a molded ZAMAC Zinc-Aluminum alloy provides lifetime protection against red rust on the head & washer. You may obtain a free copy of the written warranty upon request.
  • ZXL™ is an excellent choice for GALVALUME & other long-life metal roof panels.
  • Threads transition from fine to coarse to generate superior holding strength in various wood substrates.
  • Micro-Bit point reduces metal shavings that can embed themselves in the rubber washer.

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 & BASED UPON WOOD DENSITIES FOUND IN PRESENT DAY WOOD 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.
