Custom Knurled Slotted Thumb Screws - Steel Zinc Material

 

These custom knurled slotted thumb screws were manufactured at 5,000 pieces using low carbon steel material with zinc clear finish.  6-32 thread was incorporated at .375" length underneath the head.  Knurled head diameter was set to .313" and head height to .188".  The slotted drive was .035" +/-.005" deep and .045" +/-.005" wide.  Our customer used these custom screws in their electronics assembly process.  Full certs were made available to our customer upon request.

Custom Cross Drilled Thumb Screws - M10-1.25 X 25MM-30MM

These sweet custom cross drilled thumb screws were produced domestically using low carbon steel material with plain finish.  Two different sizes were produced: M10-1.25 X 25MM and M10-1.25 X 30MM.  The head on both sizes measured 15MM in diameter and in height.  The cross drilled holes have a diameter of 6MM with a slight chamfer at each opening.  Typically a thumb screw like this would have knurling around the head but our customer decided to forgo that feature.
