YOUNTHYE M6 (1/4") 20‑Piece 304 Stainless Steel Screw‑Pin D/Bow Shackles — Corrosion‑Resistant, 2204 lb WLL

YOUNTHYE 20-piece M6 (1/4") 304 stainless steel screw-pin D/bow shackles are compact, corrosion-resistant clevis connectors built for tying down, rigging, and light-duty towing or anchoring tasks.

These screw-pin shackles come as a set of 20 identical 1/4" (M6) D/bow-style connectors made from 304 stainless steel. Each shackle features a threaded screw pin for quick installation and secure fastening. With a specified working load and a higher breaking strength, they are intended for repeated outdoor use where rust resistance and dependable hardware matter.

How strong are these 1/4" M6 screw pin shackles for everyday jobs?

Each shackle is rated with a clear working load limit and a significantly higher breaking load, giving a safety margin for common utility tasks. They suit applications like tie-downs, small anchors, or partner components in multi-point rigging where loads stay within the rated capacity.

• Working Load Limit: 1000 kg / 2204 lbs
• Breaking Load: 3800 kg / 8377 lbs
• Maximum opening width: 1/2" (15 mm)
• Screw-pin design for quick fastening and removal

Are these shackles built to resist rust and weather exposure?

Yes — the shackles are manufactured from 304 stainless steel, a widely used marine-grade alloy that resists corrosion in wet and outdoor environments. That makes them appropriate for boats, trailers, and outdoor hardware where periodic exposure to salt spray or rain occurs.

• 304 stainless steel construction for improved rust resistance
• Polished finish reduces surface corrosion points
• Designed for repeated outdoor use without quick degradation

Which tasks and gear pair well with these small clevis connectors?

The D/bow shape and screw-pin mechanism make these shackles versatile for connecting chain, rope, anchor lines, straps, and small wire rope assemblies. They work well for light towing, tie-down points, lifting attachments under rated loads, and general hardware repairs on vehicles and watercraft.

• Connecting chain or rope to anchors, rings, or straps
• Trailer tie-downs, tarp attachments, and recovery rigs
• Sailing hardware, small boat anchor links, and marine fittings

How do I install and secure the screw pin properly?

Installation is straightforward: hand-thread the screw pin through the shackle’s eye and into the opposite hole until snug. For a secure finish, tighten the pin with a suitable wrench or tool after hand-tightening; periodically recheck tightness during use.

• Hand-screw pin until fully seated
• Use a wrench for final tightening to prevent loosening under load
• Inspect threads and mating holes for wear before reusing

Who this is for: This 20-piece YOUNTHYE shackle set is aimed at DIYers, boat owners, trailer operators, off-road enthusiasts, and maintenance professionals who need compact, corrosion-resistant connectors for light to moderate load tasks. Choose this set when you require uniform 1/4" stainless shackles for repeated outdoor use, quick swaps, or to stock a workshop with reliable small clevis hardware.
