This option upgrades any of our Ipe Clip 175pc Kits (Standard, Extreme, Extreme4, ExtremeKD) to longer #8 x 3.125" 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 100% deeper penetration into the joist (ex. with 5/4 deck boards 2" screws only provide 0.8" of penetration into the joist, whereas the upgraded 3.125" screws double that to 1.6"). Doubling the penetration translates directly into 100% greater pull down and holding strength initially, and even more than that as the deck ages and the top surface of the joists start to degrade.
The upgraded screws feature T15 drives and colour-matched powder-coated heads so they don't glint in the sun.
