Standard Compliance: Strictly complies with JIS B 1168 specifications to ensure size and load consistency.
High-strength material: SUS304 (general purpose) or SUS316 (high corrosion resistant) stainless steel, tensile strength ≥500MPa.
Safety Design:
The ring head is smooth and burr-free to avoid rope wear.
The threaded part is fully threaded to provide uniform force.
Corrosion Resistance: Passed the salt spray test (more than 500 hours), suitable for humid, chemical or marine environments.
Industrial lifting: mechanical equipment installation, heavy cargo handling.
Shipbuilding and marine engineering: deck fixing, marine equipment suspension.
Building structure: steel structure connection, temporary support point.
Agriculture and transportation: trailer, storage equipment fixing.
Stage and exhibition: lighting, sound equipment suspension.
Q1: What is the difference between JIS 1168 and DIN 580 eyebolts?
A:JIS 1168: Japanese standard, thicker ring head, tighter thread tolerance.
DIN 580: German standard, slightly thinner head, suitable for European market.
Selection suggestion: Determine according to project requirements or equipment compatibility.
Q5: How to choose between SUS304 and SUS316?
A:SUS304: Economical, suitable for general industrial environment.
SUS316: Contains molybdenum, resistant to salt spray and chemicals, suitable for marine or chemical environment.
Q4: How to calculate safe load?
A: Working load (WLL) = breaking strength / safety factor (usually 5:1)
For example: M12 SUS304 (breaking strength 6 tons) → WLL=1.2 tons
