How do you install a G80 butterfly connecting link?

Insert the two forged half-bodies through the chain link and master ring/hook, align the central holes, insert the steel load pin through the central spring retaining collar, and tap the pin until it locks securely in place.

Are Tie Shou butterfly connecting links compatible with G100 chain?

Standard butterfly links are rated for Grade 80 chains. If you are using Grade 100 chain slings, you must select G100 rated connecting links to ensure the working load limits match across all assembly components.

G80 Butterfly Connecting Links (Standard Chain Link)

Tie Shou Grade 80 butterfly connecting links (also known as standard hammerlock links or double-loop coupling links) are high-strength rigging fittings designed for connecting lifting chains to master links, eye hooks, and rigging components. Precision drop-forged from quenched and tempered alloy steel in compliance with EN 1677-1 standards, these butterfly clasps support Working Load Limits (WLL) from 1.12 Tons up to 31.5 Tons with a certified 4:1 safety design factor.

Key Engineering Advantages & Technical Features:

High-Tensile Drop-Forged Steel: Heat-treated alloy construction delivers exceptional fatigue resistance and impact strength under heavy dynamic loads.
Secure Pin & Collar Locking System: Heavy-duty load pin held firmly by a hardened central spring retaining sleeve, ensuring zero accidental disconnection.
Rapid Jobsite Assembly: Enables quick on-site fitting and disassembly of multi-leg G80 chain slings without special welding equipment.
Powder-Coated Safety Finish: High-visibility yellow or red powder coating offers long-lasting corrosion resistance and visual identification.
