Seybold Knife Bolt

Used on the Seybold CF model and most older Seybolds.

This square headed knife bolt is fitted with an integral washer. The washer rotates on the bolt but is not removable. A screwdriver slot is provided in the threaded end to aid in removal if the head gets rounded over from a worn wrench or socket.  (This is the same bolt as our B42 bolt, EXCEPT that it has a different thread pitch. The B41 has 1/2-12 threads, the B42 has 1/2-13 threads.)
