Bolts for Seybold CF 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. This bolt has 1/2"-12 threads and measures 25/32" long below the washer.  (Overall length is 1 1/4" long)  The square head measures 5/8" across the flats. The steel washer is 1/8" thick and measures 1-1/8" in diameter. 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.)  Made in USA.

See our part number W78 for a knife bolt wrench that fits these bolts.
