What to know before buying

Listing details to confirm

The listing is inconsistent about material specificity: the product description says 316 stainless steel, while the details field only says stainless steel. Listed size is 4.8x50mm/0.19x1.97in, while item diameter separately gives 4.8 Millimeters, and item dimensions are 12 x 8 x 2 centimetres. Confirm the required pin fit and material before use. No load rating or application-specific compatibility is stated, so do not rely on the general heavy-duty wording as a rating.

Who is it for?

A good fit for

Buyers replacing a pin who can match the listed 4.8 mm diameter and 50 mm length to their fitting.
People seeking a single wire-loop retaining pin for compatible trailer, boat or equipment applications.

Less suited to

Buyers needing a confirmed load-rated hitch or coupling pin.
Anyone who needs multiple pins in one package.

The supplied rating information is entirely positive, but it represents only a single rating and no written feedback is available. It cannot establish durability, fit or performance. For a small retaining pin, buyers should rely on dimension matching and the listing's stated material rather than treating that rating as confirmation for a load-bearing application.
