Pin Detent Anvil Vs. Hog Ring Anvil

In this section, I have mentioned both the detent pin anvil and hog ring anvil. But what are these in the first place? All these questions of yours will be taken away now.

Detent Pin

A detent pin actually has a hook that can very easily fit into the impact wrench’s socket with a tiny hole, especially the place it will be connected to the impact. This also uses some ball bearings with an attached spring on its side. It keeps the socket intact in place.

Hog Ring

A hog ring is similar to the detent ring, but it has a kind of circular ring just around the very end of the square, which keeps the socket secured and intact in place.

But according to many people, the hog ring can hold the wrench tighter. It actually depends on how frequently you replace your sockets.
