About This Product
GoBoard Washers for Metal Stud Framing
GoBoard® Washers with Self-Drilling Fasteners provide increased holding strength when attaching GoBoard tile backer board to steel stud framing. Each combo pack includes 100 hardened galvanized steel washers and 100 self-drilling fasteners for a complete metal-stud fastening solution.
Self-Drilling Tile Backer Board Screws
The included 1-5/8" fasteners feature a self-drilling tip that meets SAE J78 hardness and timed test requirements. Each fastener uses a #2 Phillips drive and is designed for attaching 1/4", 1/2", and 5/8" GoBoard panels to compatible steel studs.
Fast Washer Positioning and Separation
Each 1-1/4" washer includes tabs that hold it against the GoBoard surface while the fastener is installed. Reverse tabs prevent the washers from nesting together inside the package, making them easier to separate and position throughout the installation.
Strong Holding with Wider Fastener Spacing
The large washer diameter distributes holding force across the tile backer board to help prevent fastener pull-through. When installed according to current GoBoard instructions, the washers allow spacing up to 12 inches for efficient panel attachment.
Common Questions
Frequently Asked Questions
What are GoBoard Washers for Metal Studs used for?
They are used to securely attach compatible GoBoard tile backer board panels to steel stud framing. The large washer diameter distributes the holding force across the panel surface, helping provide stronger attachment and reducing the possibility of fastener pull-through.
What is included in each package?
Each package contains 100 hardened galvanized steel washers and 100 self-drilling fasteners. The washers measure 1-1/4" in diameter, while the included fasteners measure 1-5/8" long and use a #2 Phillips drive.
Which GoBoard panel thicknesses are compatible?
This metal-stud washer and fastener kit is designed for 1/4", 1/2", and 5/8" GoBoard tile backer panels. Johns Manville does not list the included 1-5/8" self-drilling fasteners for use with 1" GoBoard panels.
What type of fasteners are included?
The kit includes 1-5/8" self-drilling fasteners for compatible steel stud framing. They use a #2 Phillips drive and feature a self-drilling tip that meets SAE J78 hardness and timed test requirements.
What are the GoBoard Washers made from?
The 1-1/4" washers are manufactured from hardened galvanized steel for holding strength, durability, and corrosion resistance. Their large diameter helps spread fastening pressure across the GoBoard surface instead of concentrating it beneath the fastener head.
How far apart should GoBoard Washers be installed?
Johns Manville specifies washer placement up to 12 inches apart. Exact positioning around panel interiors, supported edges, joints, and changes of plane should follow the current GoBoard installation instructions for the specific wall assembly.
What do the tabs on the washers do?
Pre-positioning tabs hold each washer against the GoBoard surface while the fastener is driven. Reverse tabs prevent the washers from stacking or nesting together inside the package, making individual washers easier to separate during installation.
Can these GoBoard Washers be used in wet areas?
Yes. They can be incorporated into properly constructed GoBoard waterproof wall assemblies. Apply GoBoard Pro Sealant over each washer and fastener penetration, and seal all panel joints according to current GoBoard installation instructions before installing tile.
Can this kit be used with wood studs?
No. The included self-drilling fasteners are intended for compatible steel stud framing. For wood studs and subfloors, use the GoBoard washer combination supplied with 1-5/8" Hi-Lo fasteners or another manufacturer-approved wood-framing fastener system.
