These alloy steel socket head blade bolts use a Torx Plus driver and are used on most sizes of Wohlenberg paper cutters with metric screw threads. They replace the original RIBE type of blade bolts that are no longer available.
They are 19mm (.75″) long below the washer and have an M12 thread. The 4140 hardened steel washer is captive on the head; it rotates in place but it will not fall off.
