High-Strength Glass-Filled Nylon Raised-Head Thumb Screws

These thumb screws have a raised head that makes them easy to grip. Stronger than standard nylon, they're chemical resistant, nonconductive, and lightweight. A knurled head allows for slip-resistant controlled adjustment. Length is measured from under the collar.
