|Tiger Claw TC-G Grooved Board Fasteners
300 Series Heavy Gauge Stainless Steel Hidden Deck Fastener with black oxide coating.
When using Tiger Claw fasteners please review and comply with these requirements to obtain
proper installation. Failure to follow these requirements may result in deck failure and/or void of warranty.
Inspect decking material prior to installation. Omit any planks that contain hooks, twists, splits, cracks, or
other defects. Always install decking with the crown upward.
Recommended for use in 5/4" or thicker decking. If using pre-grooved decking be sure that the groove is the
correct dimension and location on the board so that it is compatible with the TC-G fastener.
(see groove specs)
A router or biscuit joiner can be used to create grooves in solid edge decking.
Use with decking no less than 7/8” in thickness.
(not recommended with decking prone to high shrinkage like Pressure Treated Pine.)
Semi gloss black finish, rectangular body with a screw hole in the bend of the bottom flange.
Two large off set opposing tabs on top, one tab with small points and the other with a rolled edge, one spacer tab
on side of fastener body.
.512” h x 1.075” w x 085” d
All work can be done quickly and easily from above using basic tools (screw gun).
TC-G will automatically create a 3/16” space between each board.
Fasteners are designed to allow decking to expand and contract naturally by sliding on the fastener
tab and still maintain hold down strength. TC-G is designed to maintain consistent spacing as deck boards expand and contract.
From the point of installation, the TC-G can handle board expansion up to 1/8” and contraction up to 3/16”.

A fastener is needed at every intersection of a joist and decking board. When using 5.5” decking with 16” on center joists:
Square footage x 1.75 = # Fasteners
For other configurations:
# Decking boards x # Supports = # Fasteners
# Fasteners / 90 = # Boxes (round up to next box)
