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.

Due to this item's size and weight we can only ship it in an economical way via Less Than Truckload (LTL) consolidated land shipping, and only to the contiguous 48 States.

For shipping inquiries to AK, HI, PR, US-VI, and international shipping, please contact us first at sales@weldingworldinc.com.

All of the destinations above we can only serve as a Free Carrier (or FCA) modality, that requires the customer to contract and pay for their carrier service of choice. We can still ship the item, but only to a warehouse/receiving office within the 48-contiguous States.

In plain terms what this means is that if you want to ship your product to any non-contiguous US territory or internationally, you, the customer, has to provide us with the warehouse address of the carrier that serves your locality with an address within the contiguous 48-US States, as we do not ship overseas on our own.
