Stainless Steel Snap Hook (DIN 5299 C) – A4/A2 Carabiner Clip

The Stainless Steel Snap Hook (manufactured to DIN 5299 Form C standards) is the universal quick-release connector for everyday rigging. Often called a “Carabiner Clip” or “Spring Hook,” our Stainless Steel Snap Hook features a spring-loaded gate that allows for instant attachment to ropes, chains, and straps, making it the most convenient hardware for dog leashes, flagpoles, and shade sails.

Product Overview: Precision-formed from Stainless Steel A4 (316) or A2 (304), this hook offers superior rust resistance compared to zinc-plated alternatives. Its smooth, polished surface prevents snagging on fabrics and ensures the spring mechanism remains snappy even after years of outdoor exposure.

Engineering Insight: Safety First

While versatile, it is crucial to understand the limits of a standard Stainless Steel Snap Hook:

• Not for Climbing: This DIN 5299 hook is for “utility” use. It is NOT rated for human support or rock climbing (PPE). For climbing, you need a certified EN 12275 carabiner.
• Marine Ready: The internal spring is also made of stainless steel. This prevents the common failure mode where the hook looks fine outside, but the rusted spring inside snaps, leaving the gate flopping open.

For more details on snap hook types, please refer to the Carabiner entry on Wikipedia.

Material Guide: A2 vs A4

• A2 (304): Perfect for camping gear, gym equipment, and keychains.
• A4 (316): Essential for diving gear, boat rigging, and seaside awnings where saltwater corrosion is a constant threat.
