Make a stronger connection and complete the layout of your deck design with the FastenMaster Tiger Claw TC-G Butt Seam Clip. A mirror-image version of the original Tiger Claw TC-G Hidden Fastener, the TC-G Butt Seam Clip from FastenMaster allows you to install two clips per joist at the butt seam, eliminating the need for extra joists and blocking. Make your deck building process easier and keep your deck surface smooth with the Tiger Claw TC-G Butt Seam Clip, crafted from Grade 304 stainless steel for lasting corrosion resistance and a strong hold. ACQ compliant and approved for use in saltwater locations, the TC-G Butt Seam fastener creates a consistent 3/16 inch deck board spacing for your entire project no matter your region.

Working with non-grooved or square edge deck boards? Use the TigerClaw Router Bit to create the perfect side-groove in one easy motion.

FastenMaster Tiger Claw Butt Seam Clips are available in packs of 55 to cover approximately 20 square feet (for 16 inch OC joist spacing) or 30 square feet (for 12 inch OC joist spacing).

TC-G Butt Seam Clip packs include the fasteners, stainless steel installation screws, and installation instructions.

Do not use TC-G Butt Seam Clips with TC-120 fasteners.
