Edelrid SCREWLINK

This screw link is designed for semi-permanent connections where you need high strength and durability, such as setting up anchors, connecting chains, or rigging systems. Unlike a standard carabiner, the screw-gate closure is intended to be tightened with a wrench for a secure, long-term connection.

Yes, this link is certified and built for high-load applications. With a major axis strength of 55 kN, it is significantly stronger than most standard climbing carabiners, making it a reliable choice for heavy-duty rigging and safety-critical setups.

Steel is much harder and more abrasion-resistant than aluminum, which makes this link ideal for environments where it will be in contact with ropes or metal hardware for extended periods. The trade-off is the weight; at 137 grams, it is heavier than an aluminum equivalent, but it offers superior longevity in high-wear scenarios.

Keep the threads clean and free of grit to ensure the nut spins smoothly. If you are using it in a coastal or humid environment, a light application of lubricant on the threads can help prevent corrosion and keep the gate operating reliably.

While the link is strong enough to handle climbing ropes, the oval shape is designed primarily for connecting hardware or webbing. If you plan to run a rope directly through it, be aware that the tight radius of an 8mm link can cause increased friction and wear on the rope compared to a larger diameter ring or carabiner.
