STAINLESS STEEL DIN5299C SNAP HOOK is a high-strength spring hook that complies with the German industrial standard DIN5299C and is precision-casted from 316 stainless steel. Designed for harsh industrial environments, its two-way locking mechanism (main spring door + secondary safety lock) provides double anti-slip protection and is suitable for key safety areas such as aerial work, stage machinery, and ship loading and unloading. Certified by EN362:2004 and DIN EN 12275, it maintains stable performance in the temperature range of -40°C to +200°C, and its special surface passivation treatment makes it still have excellent corrosion resistance in a chemical environment of PH1-14.

Triple safety system:
Automatic reset spring door
Manual rotation safety lock
Secondary anti-mis-opening card slot
Ergonomic design:
Anti-slip grooves on the thumb pressing surface (spacing 1.2mm)
Opening force 15-20N in accordance with ISO 10535 standard
Non-destructive testing:
100% eddy current flaw detection
Magnetic particle detection of key parts
Wind power maintenance: core connectors for wind turbine tower anti-fall systems
Theater engineering: fast and safe suspension of truss lighting fixtures
Port machinery: emergency release device for container spreaders
Industrial climbing: vertical lifeline terminals for petrochemical equipment maintenance
Special rescue: serial nodes for narrow space demolition equipment
Q1: How to detect spring door fatigue?
A: Perform monthly:
Free reset test (drop distance ≤ 3mm)
Tension test (4-6N opening force required)
Stethoscope detection of spring sound (abnormal metal sound indicates fatigue)
Q6: Maximum allowable lateral load?
A: 30% of the axial load (such as 50kN axial load, the lateral load does not exceed 15kN). If it exceeds, a universal joint must be installed.
Q3: Compared with EN362:2004, what are the special requirements of DIN5299C?
A: Additional requirements:
Salt spray test for 1000 hours without substrate corrosion
5000 low temperature (-40℃) opening and closing tests
Door shaft wear ≤0.1mm/10,000 operations
