GoBoard Fasteners

GoBoard® Fasteners are tile backer board fasteners designed for securing GoBoard to wood or metal studs, as well as subfloors. These corrosion-resistant fasteners have larger diameter heads for more holding power and the smooth underside of the head helps mitigate over-driving the screw. GoBoard Fasteners are available in contractor packs of 700 pieces and come with the required T-25 Torx head bit. Using GoBoard Washers is optional with these tile backer board fasteners, depending on your application.
- Wood and metals studs
- Corrosion-resistant
- T-25 Torx bit included
- Easy installation
GoBoard tile backer board fasteners are for use on:
- 1/4″ GoBoard for floors and countertops
- 1/2″ and 5/8″ GoBoard for walls, showers, ceilings, and floors

Reference the ICC ES Evaluation Report (Tables 1 through 4) for fastening schedules.

GoBoard Seam Fabric


GoBoard® Seam Fabric is a lightweight, point bonded non-woven that is specifically designed to enhance the performance of all GoBoard products. When used with GoBoard Tile Backer Board and GoBoard Wedge, installers can expect increased tensile strength at the joints and in the change of planes. Get to tile faster using GoBoard Seam fabric due to superior adhesion between GoBoard Pro Sealant and thin-set mortars. And best of all, there’s no need to wait for the sealant to skin over.
- Alkali resistant
- Improved shear bond strength (30%+)
- Increased Joint strength (50%+)
- Shortens the time to tile
GoBoard Seam fabric is available in the following dimensions and size:
- 3″ x 100 yards

GoBoard Washers


GoBoard® Washers are hardened steel washers that provide maximum holding strength when fastening tile backer board to stud framing. Each washer has tabs for pre-positioning prior to driving the fasteners. These reverse tabs also prevent the washers from stacking while packaged – making them easy to separate. When using GoBoard Washers in your installation, the fastener spacing increases to 12 inches.
- Wood and metal studs
- 12-inch spacing
- Corrosion-resistant
- East installation
GoBoard Fastener/Washer combo packs come with 100 pieces each and are for use on:
- 1/4″ for floors and countertops
- 1/2″ and 5/8″ for walls, showers, ceilings, and floors




Approved Materials
Fastening on Wood studs
- GoBoard Hi-Lo Fasteners (1 5/8″ long)
- GoBoard Washers
Fastening on Metal studs
- GoBoard Self-drilling Fasteners (1 5/8″ long)
- GoBoard Washers
Required Tools
- #2 Phillips head bit
- drill
Safety
Please wear gloves, safety glasses, long sleeve shirts, and long pants and follow good safety practices when installing GoBoard.
