Maximum Security for Critical Rigging with RiaYer
Engineered for permanent or long-term installations, our RiaYer Bolt-Type Safety Bow Shackles provide the highest level of security in the marine hardware class. Unlike standard screw-pin shackles, this model features a robust 3-part locking system: a bolt, a hex nut, and a stainless steel cotter pin.
Available in both Polished Silver and Matte Black finishes, these shackles are crafted from premium T316 Stainless Steel. The "Omega" bow shape allows for multi-directional loading, making them perfect for anchoring, towing, and heavy-duty industrial lifting where vibration might cause a standard pin to back out.
Key Features
- Triple-Lock Safety System: The combination of a threaded bolt, hex nut, and cotter pin ensures the shackle will never accidentally open, even under constant rotation or vibration.
- Marine Grade T316 Steel: Superior molybdenum content offers maximum corrosion resistance in saltwater environments (available in natural silver or premium black coated finish).
- Oversized Bolt Design: The bolt diameter (B) is significantly larger than the body (A) for enhanced shear strength.
- Wide Bow Opening: The generous interior width allows for the attachment of multiple lines, thimbles, or recovery straps without binding.
How to Install (Step-by-Step Guide)
Proper installation is critical for the safety mechanism to work effectively:
- Disassemble: Straighten the legs of the cotter pin, pull it out, unscrew the hex nut, and slide the bolt out of the shackle body.
- Attach: Align the shackle bow with your anchor chain, recovery strap, or rigging point.
- Insert Bolt: Slide the bolt through the shackle eyes and your attachment point. Ensure it seats fully.
- Secure Nut: Thread the hex nut onto the bolt and tighten it with a wrench to ensure a snug fit.
- Lock with Pin: Insert the cotter pin through the hole at the end of the bolt. Crucial Step: Bend the split legs of the cotter pin outward to lock the nut in place.

Frequently Asked Questions
Q: Why choose this "Bolt Type" over a standard screw pin?
A: Bolt-type shackles are the industry standard for permanent installations. The cotter pin prevents the nut from backing off, making it safer for applications involving vibration (like engines or towing).
Q: Is the black version also 316 Stainless Steel?
A: Yes, both Silver and Black variants are made from the same high-quality T316 Stainless Steel core.
Q: How do I measure the correct size?
A: Check the "B (Pin/Bolt)" column. This is the part that must pass through your chain link. For example, a 3/8" shackle requires a 1/2" clearance hole.
