Sea-Dog Release Pin 1/4 Inch x 1 Inch, 304 Stainless Steel Detent Quick Release Pin

The Sea-Dog 193410-1 is a standard duty detent release pin built from formed 304 stainless steel for corrosion resistance in marine environments. It is designed for basic holding and removal applications that do not require a positive locking ball feature, activated by a simple push or pull motion. The internal detent ball depresses on insertion and springs back up once through the mounting hole, giving a fast, tool-free release when the pin needs to come out.

This robust, durable design holds up to repetitive-use applications, making it a common choice for anchor clevis fittings, hinge pins, and as a replacement for cotter pins in spots where the pin has to be pulled and reinserted frequently, such as bimini top and deck hinge hardware. A split ring is included on the pin so an optional lanyard can be attached to keep the pin from being lost overboard. Note that the deck hinge itself is not included; this listing is for the release pin only.

The 193410-1 measures 1/4 inch in pin diameter (A), 1 inch overall length (B), 3/4 inch useable/working length (C), 7/16 inch handle length (D), and 1 inch across the ring (E). It is part of Sea-Dog's standard duty release pin lineup and is sized for smaller-diameter hinge and clevis applications compared to the larger pins in the same series.
