Product Introduction
Corrosion-Proof & Mission-Ready
Precision-forged from marine-grade 316 stainless steel, molybdenum-stabilised for lifetime immunity to salt-spray, acid rain and offshore humidity.
Forged, Never Bent
One-piece drop-forged blank, 100 % mag-particle inspected—zero porosity, zero weld lines, zero fatigue points under dynamic hoist loads.
Instant-Secure Latch
Self-closing 304 stainless latch with dual-torsion spring; stays locked at –40 °C to +200 °C, releases with one-hand thumb lever even with gloves.
⚙️ Technical Parameters
Product Advantage
| Advantage | Description |
| Salt & Chemical Immunity | 316 Mo-content resists pitting/crevice attack in permanent marine immersion and fertiliser-acid environments. |
| One-Piece Forging | Zero weld seams = zero heat-affected zones; keeps rated strength after 10 000+ lift cycles. |
| Mirror Electropolish | Non-stick surface, rinses free of mud, fish blood or cement dust; maintains yacht-club shine. |
| CNC Critical Faces | Eye bore ±0.05 mm for slip-fit with Grade 80 chain—no shims, no rattling, no galling. |
| Fail-Safe Latch | Spring-loaded gate over-travels 20° past nose for visual locked confirmation; redundant lock pin optional. |
❓ FAQ
Q1: Can I use these hooks for overhead lifting of personnel?
A: No—rated for cargo only. Use certified man-riding hooks when human load is involved.
Q2: Do I need to grease the swivel bushing?
A: Bronze bushing is self-lubricating. Rinse with fresh water and spray a light PTFE lube every 6 months.
Q3: Is the WLL per hook or per pair?
A: Per single hook. Always divide total load by number of attachment points.
Q4: Will the 1/4" hook accept 5/16" chain with a shim?
A: We recommend ordering the correct size; latch geometry is optimised for rated engagement depth.
Q5: How do I pass inspection after a drop?
A: Visually check for nose spread > 1 mm or latch misalignment; mag-particle test mandatory after any shock load.
