TC4 fasteners are designed specifically for creating a nail-free deck surface with extreme hardwood decking like Ipe, Brazilian Redwood and other materials essentially known as Ironwoods. The heavy gauge stainless steel with black oxide coating better hides the fasteners between the boards.

These Tiger Claw Hidden Fasteners are recommended for use in ¾” or 5/4” hardwood decking up to a nominal 4” (3.5” width). These woods experience very little expansion and contraction with normal conditions and care, but any material that may shrink or expand more than 1/8 after installation should not be used with TC4s.

Gapping: TC-4S 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 prongs and still maintain hold down strength. TC-4S can handle total board movement up to 1/8th of an inch. Check with your decking supplier to find out how much expansion and contraction you can expect from your type of Hardwood decking.

Coverage Estimator
A fastener is needed at every intersection of a joist and a support. When using 3.5 decking* with 16 on center joists:
90 pcs. box covers aprox. 38 sq. feet.
1400 pcs. bucket covers aprox. 545 sq. feet.
Or: Square footage x 2.75 = # Fasteners

For other configurations:
# Decking boards x # Supports = # Fasteners
# Fasteners / 90 = # Boxes (round up to next box)
