The OEM Row 3 profile is widely used for the Tab row (qwerty row). Please check the diagram in the product images to ensure it's the correct keycap for you.
Though notoriously difficult to work with, titanium has a unique look and feel that other metals just cannot match. These caps are machined, finished, and anodized in our Indiana workshop, giving us complete control over all aspects of the manufacturing process. Each keycap is machined from a single piece of solid titanium, with the stem dimensions accurate to a thousandth of an inch for an excellent fit on the keyswitch. As titanium is a very light metal, these have little effect on actuation pressure when mounted to the keyswitch.
