ZORUNNA 3/8" D-Ring Shackles 10-Pack — Galvanized Screw-Pin Clevis, 1-Ton WLL

ZORUNNA 10-piece 3/8" galvanized screw pin D-ring shackles are heavy-duty carbon steel connectors designed for secure rigging, towing, and outdoor gear attachments with a 1-ton working load limit per shackle.

These 3/8" (10 mm) clevis shackles come as a matched set of ten, each featuring a screw pin (bolt) closure and a galvanized finish to resist rust and abrasion. Built from carbon steel with a deep-thread pin and a bur-free body, the shackles balance strength and safety for tasks ranging from light towing and cargo handling to camping rigging and marine use. The compact 16 mm maximum opening and thickened pin help concentrate load distribution while making installation straightforward with common tools.

How do these shackles improve connection security?

Secure connections depend on design and fit. The deep-thread screw pin and slightly thickened cross-pin reduce slippage and increase shear strength, while the D-shape concentrates load along the bow and pin for predictable performance under tension. The burr-free finish lowers wear on ropes and straps.

• Deep-thread screw pin prevents accidental loosening under vibration
• Thicker pin increases shear area and load capacity
• D-shaped body directs force through the strongest parts of the shackle
• Smooth, burr-free surface reduces chafing on ropes and straps

What working limits and dimensions should I expect?

Each shackle is rated to a working load limit (WLL) of 1 ton (2,204 lb), sized for general-purpose rigging and light towing. The internal maximum opening is approximately 16 mm, suitable for most medium-diameter chain links, rope thimbles, and soft shackles when used as a hardware anchor.

• Diameter: 3/8" (10 mm) steel body
• Maximum opening: ~16 mm for pins and fittings
• Working load limit: 1 ton / 2,204 pounds per shackle
• Set includes 10 identical screw-pin D-ring shackles

How do they stand up to outdoor and marine conditions?

The galvanization adds a protective zinc layer that slows corrosion and wear, making the shackles more suitable for damp, salty, or dirty environments than bare steel. While galvanized coating offers solid protection, regular inspection and maintenance will extend lifetime under harsh conditions.

• Galvanized finish improves resistance to rust and salt spray
• Carbon steel core provides high tensile strength for repeated use
• Recommended: rinse after saltwater exposure and lubricate threads
• Inspect threads and body before each critical lift or tow

How should I use and care for these shackles safely?

Use the screw pin fully engaged and hand-tightened; for higher-vibration applications, secure the pin with a retaining method accepted in your use case. Never exceed the marked working load limit and avoid side-loading the shackle body, which can dramatically lower safe capacity.

• Always close screw pin completely and hand-tighten
• Do not side-load; align load along the shackle’s crown and pin
• Regularly check for corrosion, deformation, or thread damage
• Replace the shackle if bent, cracked, or if threads are worn

Who is this for? ZORUNNA's 10-piece 3/8" screw pin D-ring shackle set suits outdoor enthusiasts, DIYers, small-boat owners, and light industrial users who need dependable, affordable hardware for towing, anchoring, or fastening tasks. Choose this set if you want a practical assortment for camp rigging, cargo tie-ins, or general workshop use, but always observe the 1-ton working load limit and routine inspections for safety.
