M5-0.8 x 20 18-8 Stainless Steel Metric Button Head Socket Cap Screw gives metric equipment a broad button-head bearing surface with a clean exposed profile. The domed head reduces projection while the internal hex drive keeps installation access centered from the top.

Food-equipment panels, washdown-adjacent covers, and stainless access plates often use this shape for a clean visible surface. Cold Headers can quote metric button head requirements without steering the request toward a different head style. Because the socket is shallow compared with a full-height cap screw, use the correct metric hex key to protect the drive. For metric prints prioritizing maximum mechanical strength, Alloy Steel Metric Socket Head Cap Screws are the comparison family.
