The Ronstan Halyard Shackle - 4.8mm (3/16") Pin is a precision rigging component engineered for marine and automotive applications where secure load attachment is critical. Whether you're securing tie-down straps on a trailer, anchoring cargo to a vehicle frame, or managing halyard systems on a boat, this shackle delivers dependable fastening without failure. Mechanics and fabricators rely on properly rated shackles to ensure safety and compliance with load-carrying standards, making material quality and pin diameter fundamental to any secure fastening solution.

Designed by Ronstan—a manufacturer known for marine-grade hardware—this halyard shackle features a 4.8mm (3/16 inch) pin diameter that provides optimal strength-to-weight balance for moderate load applications. The compact 1 x 1 x 2 inch profile and lightweight 0.1 lbs construction make it ideal for weight-sensitive setups where bulk cannot be tolerated, such as custom suspension harnesses or emergency recovery kits. The shackle's design accommodates standard rope, webbing, and cable, with the pin diameter determining working load capacity and ensuring compatibility with matching hardware throughout your rigging system.

Fabricators, off-road enthusiasts, and automotive restorers benefit most from Ronstan's precision engineering when building custom winch systems, cargo securement rigs, or boat trailer assemblies. The 3/16 inch pin diameter aligns with industry-standard halyard and tie-down specifications, ensuring seamless integration with complementary shackles, carabiners, and cable attachments. Installation is straightforward—simply thread the pin through your webbing or rope eye and secure with the provided hardware, verifying proper seating to prevent slippage under dynamic loads.
