Wohlenberg Knife Bolt WG5038127 SAE Threads PPEB61

Knife bolts for Wohlenberg Paper Cutters.  (Equivalent to RIBE 2102407 and Wohlenberg WG5038125)  These alloy steel socket head blade bolts use a Torx Plus driver and are used on most sizes of Wohlenberg paper cutters with English screw threads. They replace the original RIBE type of blade 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 220CM guillotine paper cutters that use English Screw Threads.  They are .70″ long below the washer and have a 1/2-13 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.
