Wohlenberg Knife Bolt WG5038126 Metric Threads PPEB63

Knife bolts for Wohlenberg Paper Cutters. (Equivalent to RIBE 2100544 and Wohlenberg WG5038126) These alloy steel socket head blade bolts use a Torx Plus driver and replace the original RIBE type of bolts that are no longer available. These are typically used on Wohlenberg 76, 90, 92, 107, 115, 132, 135U, 137, 155, 165, 180, 185, and 220 guillotine paper cutters that use Metric Screw Threads.  They are 25mm (.98″) 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.

While it is possible to tighten and remove these with a Torx driver, they are designed for a Torx Plus driver. Using the incorrect driver will eventually strip the bolt head.
