With a 75mm frame, the 3-Inch Heavy Duty Stainless Steel Spring Snap Hook secures loads up to 140kg. Marine-grade 304 or 316L steel construction prevents oxidation in high-humidity environments. This 3 inch spring snap hook utilizes an interlock tooth for structural stability under heavy tension.
Key Features
- 304/316L Steel Grade: Industrial alloy construction resists oxidation from heavy rain. It won't rust during long-term outdoor exposure.
- Interlock Tooth Design: Mechanical teeth lock the gate tip against the frame. This stops the hook from sliding open.
- Quick-Release Gate: Tension-based spring mechanism provides instant access to the hook eye. It snaps shut immediately upon manual release.
Frequently Asked Questions
What is the weight capacity of a 3 inch snap hook?
The working load limit for this 75mm hook is 140kg. Exceeding this mass risks mechanical failure of the spring gate.
Is 304 stainless steel rust proof in salt water?
While 304 steel resists fresh water, salt water causes pitting over time. Use 316L for marine grade snap hook performance in saline conditions.
