MS20470AD6-4 | براشيم صلبة عسكرية | 3/16 X 1/4" | رأس عالمي | ألمنيوم 2117 (1000 / عبوة)

I was a little worried the universal head might not sit flush enough, but they countersink beautifully into the sheet metal. The 2117 aluminum is plenty strong for aircraft panels and they drive true every time.

Had to replace several rivets on an old trailer panel, and these 3/16 x 1/4" ones set cleanly with my hand squeezer. The universal head sits flush enough for most sheet metal work, and a thousand in the box means I’ve got spares for the next project.

Installed these 3/16 x 1/4" solid rivets on an aluminum panel project and they set beautifully with a clean universal head. The 2117 aluminum material is exactly what I needed for permanent sheet metal fastening—no complaints at all.
