These heavy duty thumbscrews are CNC machined from solid stainless steel and knurled across the top diameter to achieve the strongest grip while fastening your equipment!  These are 1/4-20 threaded and are available in sizes of 1/2", 5/8" and 3/4" length. 

The thumbscrews also come with a synthetic polymer washer which sits at the top of the threaded shaft.  This washer acts as a buffer between your stainless steel and aluminum plates to avoid scratching or dulling the anodized aluminum! 

These thumbscrews are now provided standard with all new equipment purchased throughout our Cisco product line; they can also replace any thumbscrews previously used for your Cisco, Big Jon and Bert's equipment that utilize a standard 1/4-20 thread!
