WEST MARINE
Galvanized-Steel Screw Pin Anchor Shackles

Roughly the same strength as proof coil chain of the same size. To prevent accidental opening, always seize the shackle pin with safety wire. For increased strength, use one size larger than the chain, especially with High-Test chain (the pins will still fit).

Shopping for shackles I came across these suggestions from Practical Sailor:
Get grade B. The more common Grade A (3/8-inch) shackles have a WLL of approximately 1 ton, and Grade B shackles have a WLL of approximately 2 tons. Makers distinguish their shackle grades by coloring the pins: For example, the Crosby uses silver; Peerless (Peer-Lift line) uses blue pin; and Campbell uses orange.
Rated shackles have the WLL stamped on their body, along with the country of origin, a code indicating when the shackles were made and by whom, and their size (i.e. 3/8 inches).
Use largest possible size. Be sure to buy the maximum size possible, even if the shackle needs a bit of help to fit the anchor shank.
Buy American made. They will be made to specific standards. WM's Chicago brand shackles are expensive, but you may not want to horse around with cheapies from China that may not be standard quality.

These shackles are not of a high enough grade for use with G4 high test anchor chain. For example, it would take a 1/2" shackle of this grade to get an adequate SWL for 5/16" G4 chain. For safety, go with a G4 or higher rated shackle. Also, consider using a Safety Anchor Shackle design so you don't have to wire the pin. An example of a high quality safety shackle in 3/8" size would be something like CM's model M848AG (SWL 4,000). Difficult to find unless West Marine starts carrying them, but worth the effort for the peace of mind.
