ST FASTENING SYSTEMS is a leading supplier of threaded fasteners to the pre-engineered metal building and post frame building industries. Product is shipped from two convenient service centers in Tyler, Texas, and Cincinnati, Ohio.

The heart of the ST FASTENING product line is the MAXX STEELBINDER self-drilling screw. Its drill point design consistently penetrates high tensile steel with no “point walking.”

The KWIKSEAL WOODBINDER MB with micro-bit engineering has a unique drill point that replaces the Type 17 sharp point. The micro-bit is more consistent in its drilling. It will drill multiple thicknesses of steel commonly found in metal roof ridge cap applications more consistently than a sharp point. Metal “pigtails” caused by sharp points are eliminated.

Zinc plating and clear chromate are standard on all metal building and post frame building screws. State-of-the-art POWDERFUL powder coating paint is an environment-friendly process that uses no chemical solvents and provides a tough barrier coat shell. For metal roofs offering a 40-year or longer written warranty, the ZXL STEELBINDER and ZXL WOODBINDER MB micro-bit drill point complete the system. Both have a ZAMAC zinc aluminum alloy molded head. A written warranty is available upon request. Pipe flashings, solid and vented foam closures and rolls, wafer and pancake screws for standing seam roofs and other accessories round out the product line. 

In 2019, ST introduced its #12 WOODBINDER OSB fastener for attaching metal roof panels to OSB and other light density wood substrates. A ZXL version is also available.

ST FASTENING would like to thank the readers of Rural Builder magazine for awarding it a Gold Key of Excellence award for 2022. RB
