Knurled Thumb Screws & Nuts


Knurled Thumb Screws & Nuts

PIC Design offers Knurled Thumb Screws and Knurled Thumb Nuts in both inch and metric sizes.  Knurled Thumb Screws have small ridges on the head allowing for a better grip and rapid assembly than would be provided by the originally smooth metal surface. Knurled Thumb Nuts have a round, knurled outside diameter which helps in tightening or loosening the nut without the use of a tool.  Threads are offered in standard sizes from #4-40 to 1/4-20.
