17179 Screw #4-40 x .781 Captive Type 1, Brass Nickel Plate


The 17179 may be purchased to replace a lost or damaged thumb screw. One thumb screw is used with our A100 and A105; two thumb screws are used with the CS110, CFM100, NL115, NL116, and NL121. The thumb screws secure the CR1000M Module to the CS110 case. For a CFM100, NL115, NL116 or NL121, one thumb screw secures the device to the CR1000WP or CR3000, and the other thumb screw secures the lid of the device to the card slot cover.
