Screw Pin Chain Shackles Product Overview
Designed for high-tension environments, these U shackles consistently form robust pendulous or tensioning string groups across overhead lines. They stand out as some of the best d shackles available for utility reinforcement.
- Constructed primarily from high-grade Hot-Dip Galvanized (H.D.G) steel to ensure lasting structural stability.
- Equipped with a parallel clevis cotter pin manufactured entirely from stainless steel.
- Engineered to function seamlessly as standard D shackles in varying heavy-duty applications.
- Backed by professional technology support to guarantee secure and easy-to-use mechanical connections.
Screw Pin Chain Shackles Key Features
Procuring the U-series hardware guarantees a resilient network installation supported by highly efficient direct-factory B2B terms:
- Environmental Endurance: Highly corrosion-resistant H.D.G materials ensure excellent performance and a long operational lifespan.
- Certified Manufacturing: Produced under a strict quality control plan within ISO 9001, ISO 14001, and ISO 18001 standard facilities.
- Order Flexibility: Zero Minimum Order Quantity (MOQ) on initial purchases, and a 100-piece threshold for subsequent orders. Free samples are available (buyer covers freight).
- Project Readiness: Low factory pricing, fast quotations, dependable after-sale service, OEM availability, and complete tender documents ready for submission.
Screw Pin Chain Shackles Applications
Built specifically for overhead string assemblies, this connecting hardware provides crucial utility reinforcement. It is used strictly for:
- Connecting insulators and protective fittings securely to the main pole structure.
- Forming stable pendulous or tensioning string groups.
- Supplying large-scale low and medium-voltage (LV and MV) EPC material lots consistently.
