Cascade Capscrew M8 x 20 Grade 8.8 – CA787375

Cascade Corporation specifies this M8 hex capscrew, 1.25mm thread pitch and 20mm length, at property class 8.8, for the Base Unit, Frame Cylinder, and Arm Group of its 55E Single-Double Pallet Handler. Quantities run ten in the Base Unit, one at the Frame Cylinder, and eight in the Arm Group.

At M8 by 1.25mm pitch, this is smaller than the M16 hardware Cascade uses elsewhere in its attachment mounting systems, consistent with a secondary mounting point rather than a primary structural connection. Property class 8.8 is the metric strength designation, distinct from the imperial Grade 8 marking, and the two are not interchangeable specifications despite the similar number.

Thread pitch is the specification most easily missed when substituting hardware. A bolt close in diameter and length but off on pitch will not thread correctly even though it appears to fit. At 20mm, the length is sized to a specific mounting thickness within the Cascade interface, so confirming it alongside the M8 by 1.25 thread specification keeps the fastener seating and torquing to the standard Cascade engineered it to.
