Make precise adjustments where tight tolerances are critical. With ultra-fine threads, these thumb screws are often found on measuring devices and photonic equipment. The rolling ball tip maintains contact and swivels 360° so you can make adjustments without loosening the screw. The narrow width of the head allows these thumb screws to fit in spaces with limited clearance. The knurled texture creates extra grip as you twist. These thumb screws combine the strength of stainless steel with a lightweight plastic head that won’t rust.

Length is measured from under the head.
