ProTek RC 3x25mm "High Strength" Flat Head Screws (10)

Awesome 12.9 grade screws. The ProTek high strength hardware is my go-to for restocking my screw sets. The only other place I've found similar, reliable quality hardware any cheaper is from a couple dedicated online hardware sellers. But it's almost always much easier to just add a few of the ProTek screw sizes to my cart on Amain with an existing order.

Flat head screws are especially hard to find quality versions of because their hex drives strip out so easily. I am very impressed with the hex drive quality of these screws.
