Eye bolt | A2 | M8264
An eye strap, also called a lashing eye in A2 stainless steel with a diamond-shaped base plate, is a robust and reliable component for lashing and anchoring cargo, cables, and equipment. It is manufactured from high-quality stainless steel to ensure long durability and resistance to corrosion, even in demanding indoor and outdoor environments such as industry and transport. The fitting consists of a heavy-duty eye and a base plate.
AREA OF USE
The eye strap is used to create a secure anchor point when lashing cargo, cargo nets, and straps in transport, construction, and industrial environments. It is well-suited for outdoor use where moisture and rain could otherwise cause rust. For marine environments and saltwater, acid-proof A4 is recommended. The advantages of using a stainless steel eye strap include high load capacity, easy installation, and a long service life even in exposed environments.

FREQUENTLY ASKED QUESTIONS (FAQ)
What is the advantage of a diamond-shaped base plate on an eye strap?
The rhombic (diamond) base plate offers several design advantages compared to round or rectangular deck eyes:
-
Optimal force distribution: The screw holes are placed further apart along the tips of the diamond, providing a longer lever arm and distributing tension and shear forces more effectively into the surface.
-
Space-efficient installation: The narrower profile makes it easier to mount the fitting on narrow surfaces such as posts, beams, bulkheads, railings, and profile tubes where width is limited.
-
Reduced stress concentration: The angles of the rhombic plate distribute the load more smoothly, which reduces the risk of cracking in thinner sheet metal or fiberglass.
Why is A2 stainless steel (AISI 304) suitable for lashing and anchoring?
A2 steel (1.4301 / AISI 304) provides an ideal combination of mechanical strength and corrosion protection for most demanding environments:
-
Weather and moisture resistant: Withstands continuous outdoor exposure, moisture, and rain without forming brown surface rust or weakening the weld between the eye and the plate.
-
Mechanical toughness: Austenitic stainless steel has high fracture toughness, meaning it can absorb dynamic jerks and vibrations from lashing straps, tension straps, and ropes without suffering brittle fracture.
-
Versatile use: Very popular for cargo anchoring in trailers, transport vehicles, industrial assembly lines, scaffolding, and for general anchoring in outdoor settings.
How should the eye strap be installed for maximum strength and safety?
-
Correct screw selection: Use countersunk screws (e.g., countersunk wood screws or countersunk machine screws DIN 7991 in A2) so that the screw heads lie completely flush in the mounting plate's countersunk holes. This prevents ropes and tension straps from being chafed by protruding screw heads.
-
Through-bolts for heavy loads: For higher loads or thinner surfaces (such as plastic, fiberglass, or thin plywood), through-bolts with a large fender washer (DIN 9021 A2) and a locking nut on the back are recommended instead of standard wood screws.
-
Placement in the direction of pull: Orient the long side of the diamond in the main direction of pull to utilize the strength of the fitting optimally.
