No, only Type 316 stainless steel clevis forgings are available off the shelf. Suppliers choose not to double inventory them since 316 stainless is virtually identical in strength to 304 stainless and provides more corrosion resistance. Type 304 stainless threaded rods are frequently supplied with Type 316 stainless clevises. If a 304 stainless clevis is absolutely required, they can be machined but at a premium price and longer lead time.
