NAS1097B3-5 | براشيم صلبة عسكرية | 3/32 × 5/16 بوصة | رأس مخفض | ألومنيوم 5056 (5000 / عبوة)

Used about 300 of these on a sheet metal repair job and they set cleanly with no mushrooming. The 5056 aluminum feels a bit softer than standard steel rivets, which actually made bucking them easier.

The reduced head design made setting these flush on thin sheet metal much easier than with standard domed rivets. I went through about 400 of them on a small panel project and only had one that didn't set perfectly. The 5056 aluminum feels sturdy enough for structural work but still easy to buck.

Needed a solid batch of rivets for some panel repairs, and the reduced head design sits nicely flush without interfering with adjacent pieces. The 5056 aluminum feels sturdy enough for permanent fastening, though I wish the package included a few extras for inevitable drops.
