This option upgrades any of our Ipe Clip 175pc Kits (Standard, Extreme, Extreme4, ExtremeKD) to longer #8 x 2.5" screws for greater pull down and holding strength. Since the screws insert on a 45 degree angle and a portion of them is taken up in the deck board above the joist, these longer screws can provide 38% deeper penetration into the joist (ex. with 5/4 deck boards these longer screws will penetrate the joist to a depth of 1.3", versus just 0.9" for the standard 2" screws). That deeper penetration translates directly into 40% greater pull down and holding strength!
The upgraded screws feature T15 drives and black colour-matched heads to blend in with the black-annodized stainless steel reinforcement plate that they seat into, yielding a great overall appearance that is truly fastener-free.
