About This Product
GoBoard Washers for Wood Stud Framing
GoBoard® Washers with Hi-Lo Fasteners provide increased holding strength when attaching GoBoard tile backer board to wood studs and subfloors. Each combo pack includes 100 hardened galvanized steel washers and 100 Hi-Lo fasteners for a complete wood-framing fastening solution.
Hi-Lo Tile Backer Board Screws
The included 1-5/8" fasteners feature Hi-Lo threads for increased holding power and reduced driving torque in wood. Each fastener uses a #2 Phillips drive and is designed for attaching 1/4", 1/2", and 5/8" GoBoard panels to compatible wood framing.
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 Wood Studs used for?
They are used to securely attach compatible GoBoard tile backer panels to wood studs and wood subfloors. The large washer diameter distributes 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 Hi-Lo 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 wood-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" Hi-Lo fasteners for use with 1" GoBoard panels.
What type of fasteners are included?
The kit includes 1-5/8" Hi-Lo fasteners with a #2 Phillips drive. The Hi-Lo thread design provides increased holding power while reducing the driving torque required when fastening compatible GoBoard panels to wood studs or subfloors.
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 or subfloor assembly.
What do the tabs on the washers do?
Pre-positioning tabs hold each washer against the GoBoard surface while the Hi-Lo 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 assemblies. Apply GoBoard Pro Sealant over every washer and fastener penetration, and seal all panel joints according to current GoBoard installation instructions before installing tile.
Can this kit be used with metal studs?
No. The included Hi-Lo fasteners are intended for compatible wood studs and subfloors. For steel stud framing, use the GoBoard washer combination supplied with 1-5/8" self-drilling fasteners or another manufacturer-approved metal-framing fastener system.
