The Greatest Thumb Nut in History
M5 x .8 Thumb Nut at Cool Screws.
One Nut. The Greatest Thumb Nut in History. This Beast is 1-3/8 inch in Diameter and Weighs over 3 ounces. We developed this 5 mm Nut to beef up the Positioning Arm and its unbreakable. We take every opportunity to make improvements. This nut is chunky, with a beautiful finish, and perfect knurl, and looks really cool. This nut is going to work its way into other products but it works so nicely on the Positioning Arm I thought to share it here.
