ST-XL™ MB™ WoodBinder®
Designed as an alternative to the zinc-aluminum alloy head. It is also used to attach steel roofing used in post-frame & residential construction. The smaller cupped HWH provides an attractive low-profile appearance versus larger HWH fasteners.
304 Stainless Steel cap provides lifetime warranty against red rust on the head & washer. You may obtain a free copy of the written warranty upon request.
ST-XL™ is an excellent choice for GALVALUME or other long-life metal roofs.
The combination of a Micro-Bit™ drills 29 & 26 gauge consistently & eliminates the metal shavings that can embed themselves in the EPDM rubber washer.

Metal to wood fastener designed as a low profile alternative to attach attach steel roofing & siding, including GALVALUME and other long-life roof panels used in post-frame and residential metal roofing applications.
NOTES:
- 1-1 /2” LENGTH FULLY PENETRATES OSB AND PLYWOOD SHEETING
- 26 AND 29 GA. VALUES SHOWN WERE OBTAINED USING 80 KSI STEEL SHEETING. 24, 22, AND 20 GA. VALUES WERE OBTAINED USING 50 KSI MINIMUM STEEL SHEETING.
- BMT DENOTES BASE METAL THICKNESS AFTER REMOVAL OF PAINT FINISH AND METALLIC PROTECTIVE COATING.
- ALL STRENGTH VALUES SHOWN ARE ULTIMATE VALUES, EXPRESSED IN LBS. APPLY AN APPROPRIATE SAFETY FACTOR TO OBTAIN DESIGN LIMITS.
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 USE OF 304 SS SCREWS MAY CAUSE BLISTERING ON ALUMINUM PANELS DUE TO THE MANY DIFFERENT ALLOYS FOUND. CHECK WITH THE ALUMINUM PANEL SUPPLIER FOR PROPER FASTENER RECOMMENDATION.
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.
