Frequently Asked Questions
What does a countersunk pad do?
A countersunk pad features conical holes that allow flat-head fasteners to sit flush with the pad surface. This pad has four 21/64" countersunk holes sized for 5/16" hardware.
Why 1/4" thickness instead of 3/8"?
The 1/4" thickness reduces weight and cost for lighter-duty applications where the full 3/8" structural capacity is not required.
