Choose the Correct Fit
Confirm that the hardware is a 13/16-inch penta bolt. A standard hex opening is a different profile.
Use a compatible 1/2-inch square-drive impact tool or adapter. Engage the pin-detent retaining arrangement before use.
Installation & Care
Check the space around the recessed bolt and any protrusion. The socket must seat fully without binding in the access opening.
Clear grit from the penta opening and drive end. Inspect the corners and wall for wear or cracks before reuse.
