Hinge | stamped | A2 | M8046
If you are looking for a hinge that is both durable and affordable, a stamped A2 stainless steel hinge is a reliable choice. By being stamped from stainless steel sheet metal, the hinge features a lighter construction while maintaining strength and durability.
Manufactured from A2 / AISI 304 stainless steel, it withstands moisture, rain, and temperature fluctuations in normal indoor and outdoor environments. Thanks to the material's good corrosion resistance, these hinges are used where wear resistance is important, but a simpler design is sufficient. For saltwater and marine environments, acid-proof A4 is recommended.
APPLICATION AREA
Stamped A2 stainless steel hinges are used for mounting hatches, doors, cabinets, and inspection doors indoors and in normal outdoor environments, such as in sheds, on fences, outdoor furniture, boxes, and machine covers. They are installed with stainless steel screws in pre-drilled holes according to the hinge's hole pattern.

FREQUENTLY ASKED QUESTIONS (FAQ)
What is the difference between a stamped hinge and a cast hinge?
Both types offer good corrosion protection in stainless steel, but the manufacturing methods provide completely different profiles and areas of use:
-
Stamped hinge (bent sheet metal): Manufactured by stamping stainless sheet metal and bending it around the hinge pin. This results in a lighter construction, lower profile, and a more cost-effective product that is perfect for standard hatches, storage boxes, chests, and simpler doors.
-
Cast hinge (solid): Form-cast in one piece with thicker material and beveled edges. It is intended for significantly heavier mechanical loads, torsional rigidity, and when an exclusive mirror-polished finish is requested.
Why is stainless steel A2 (AISI 304) a good material for stamped hinges?
The hinge's function is based on a moving joint (the pin), and the choice of material determines whether the joint remains free from rust:
-
Weatherproof: A2 steel (1.4301 / AISI 304) withstands rain, snow, moisture, and condensation in normal indoor and outdoor environments (corrosivity class C3).
-
No rust in the joint: Electro-galvanized hinges risk rusting inside the bent sleeve around the pin, which causes the hinge to seize. Stainless A2 retains a smooth motion year after year.
-
When is A4 needed? For boats, docks, coastal environments, pools, and chemically aggressive environments, you should choose a hinge in acid-proof A4 steel (AISI 316).
What is the best way to mount a stamped A2 hinge?
-
Selection of fasteners: Always use screws in stainless steel A2 or A4 (e.g., countersunk wood screw or countersunk machine screw DIN 965/ISO 7046) to avoid galvanic corrosion between the screw and the hinge.
-
Attachment to thin surfaces: Since a stamped hinge is flat and light, it is excellent for mounting with through-bolts, washers, and lock nuts (DIN 985 in A2 or A4) on thinner plastic, fiberglass, or sheet metal hatches.
-
Placement of the pin: If possible, mount the hinge so that the hinge pin does not sit in a constant water trap, which reduces the buildup of water and dirt in the joint.
