The lens flange screw M6 × 16 mm (NOR00696) is a standard part according to ISO 7380-2 made of A2-70 stainless steel. It is used on the door leaf of the HT Group gas-tight hinged door to secure the inspection cover of the safety locking mechanism.

The inspection cover closes the service opening in the door leaf and is sealed gas-tight using the PTFE gasket HBZ02343. The cover is fastened together with sealing washers HBZ04286, ensuring that the screw connections themselves are also gas-tight. The flat lens head with flange distributes the contact pressure over a larger surface area and has a low profile.

This version corresponds to screw NOR01541, but is made of A2-70 stainless steel and is intended for doors with normal corrosion exposure. Whenever the inspection cover is removed, the screws and sealing washers must be checked for damage and replaced if necessary.
