Delivery and Shipping 🕐 1 hour from Order to Fulfillment

At Frank’s Fasteners, we aim to bolt your order out the door within 1–2 business days. Orders placed over the weekend or on public holidays will be screwed into the queue the next working day.

If we hit a snag—like stock running low or a part going missing—we won’t leave you hanging. One of our team members will reach out by phone or email to keep you in the loop with an updated delivery ETA.

We ship all orders via Royal Mail 24 as standard, with upgrade options including Royal Mail Special Delivery Guaranteed or courier services. For extra bulky or heavy orders, a courier may be used automatically—we know when it’s time to bring in the heavy-duty tools.

A surface cup finishing washer, often referred to as a "cup washer" or "finishing washer," is a type of washer used in fastening applications to provide both functional and aesthetic benefits. 

These washers have a distinct cup-like or conical shape, with the central hole designed to accommodate the head of a screw or bolt. The concave design helps to encase the screw head, providing a more finished and professional appearance.
