Super Duplex Stainless Steel Dss 2507 2205 Torx Slot S Shaped One Way Pan Head Security Bolt Anti Theft Metal Screw

Super Duplex Stainless Steel Dss 2507 2205 Torx Slot S Shaped One Way Pan Head Security Bolt Anti Theft Metal Screw

This high‑end security bolt is manufactured from Super Duplex Stainless Steel grades SA182 F60 (2205), F61, F65, as well as 2507. These alloys provide outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, even in warm chloride‑rich environments. The drive is a Torx slot combined with an S‑shaped recess – a non‑standard geometry that effectively prevents unauthorised removal. The pan head offers a low profile and good load distribution. This bolt is designed for the most demanding anti‑theft applications in aggressive environments, such as offshore, chemical, and marine industries. The “S‑shaped” drive adds a unique layer of security not found in common tamper‑proof fasteners.

• Offshore oil and gas platform equipment – extreme chloride exposure.

• Chemical reactor manway covers – high strength and corrosion resistance.

• Desalination plant high‑pressure piping access flanges.

• Bridge expansion joint covers in coastal areas.

• Subsea equipment junction boxes (non‑pressure retaining).

• Super Duplex material – PREN >40, yield strength >550 MPa, exceptional corrosion resistance.

• S‑shaped + Torx drive – unique security profile, no standard bit available.

• Pan head – low profile, wide bearing area.

• Ideal for extreme environments – seawater, acids, high chloride.

• Anti‑theft by design – cannot be turned with any common tool.
