Tiger Claw TC-120 Hidden Fasteners are designed specifically for creating nail-free deck surfaces with ¾” thick grooved boards manufactured from mahogany and ironwood decking.

If the decking is pre-grooved, be sure to verify the groove dimension and location for compatibility with the TC-G fastener. To create groove in solid edge decking, use a router, biscuit joiner or the Tiger Claw Slot Cutter.

Features and Compatibility

Workability: All work can be done quickly and easily from above using basic tools (screw gun)

Recommended Screw: Quality Stainless steel #6 x 1 5/8 finished head decking screw. Screws included in each bag.

Gapping: TC-120 will automatically create a 1/8 space between each board

Expansion / Contraction: Fasteners are designed to allow decking to expand and contract naturally by sliding on the fastener tab and still maintain hold down strength. TC-120 is designed to maintain consistent spacing as deck boards expand and contract. From the point of installation, the TC-120 can handle board expansion up to 1/8 and contraction up to 3/16

Packaging: 90 pieces per bag

Bag: 90 Tiger Claw fasteners, (92) #6 x 1 5/8 stainless steel screws, (1) #1 Square Drive Bit, (1) Installation Instruction, (1) Support Addendum

Coverage Estimator
90 pieces covers 50 sq. ft. when using 5.5 decking and 35 sq. ft. when using 3.5 decking.

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 = Approx. # of fasteners
When using 3.5" Decking with 16" on center joists:
Square footage x 2.75 = Approx. # of fasteners

For other configurations:
# Decking boards x # Supports = # of Fasteners
# Fasteners / 90 = # Bags (round up to next bag)
