Zeron 100 SA socket head cap screws are super duplex stainless steel fasteners (UNS S32760 / Werkstoff 1.4501) with internal hex drive in a cylindrical head per ASME B18.3 / ISO 4762 / DIN 912. Internal hex lets the bolt seat into a counterbore for flush-with-surface installs, equipment housings, instrument panels, machined-block flanges. SA is the cost-effective baseline; FG SHCS for high-load NORSOK / API; FLT SHCS for subsea / arctic.
