Customer Reviews (4.4 / 5 · 5 reviews)

Evelyn F. ★★★★★

Used these to mount deck railing brackets outside. The 18/8 stainless steel is holding up well after a few rainstorms, no rust spots at all. The 1-3/8 length was just right for sandwiching two pieces of wood.

Richard ★★★★★

The Phillips head seats perfectly in my driver without slipping, and the 18/8 stainless feels solid. These are holding up great on a mailbox I mounted outside a few months ago.

Edward ★★★★★

Ordered a pack of 300 for a project and they showed up exactly as specified—the 18/8 stainless is nice and non-magnetic, so they won't cause issues near sensors. The Phillips heads drive cleanly without stripping, which is more than I can say for cheaper hardware I've used.
