The holes themselves

Three factory sockets. Nothing carved in the back room.

A port, on this bench, is a hex socket the factory already cut. You can put a driver in it. You can take a plug out of it. If a head needs a cavity we would have to mill, it does not belong on the 1st Ave tray.

Some rooms treat mass as a secret poured into a cavity and capped. That work has its place. It is not our place. Tungsten Bay started because Wren got tired of golfers buying a new stamp when the old stamp still had empty sockets. The sockets are the product. The grams are the adjustment.

We keep a tray of 2, 4, 6, 8, 10, and 12 gram hex plugs in tungsten. Aluminum blanks fill a hole when we want the socket occupied but almost weightless. Nylon washers that came from a big-box bag go in the trash — they crush, they steal torque, they lie about the gram you think you installed.

A head with a sliding rear track is still a visible system. We treat the track slider as a back screw with extra travel. A head with no socket at all is a conversation about a different shop.

Heel socket

Closest to the hosel. Walking mass here shortens the lever that wants to hold the face open. Read the dedicated heel page if that is the miss you keep drawing in the dust.

Heel screw notes

Toe socket

Farthest from the hands. Walking mass here lengthens that same lever. Billings crosswind off the rims makes this socket busier than a coastal shop would guess.

Toe screw notes

Back socket

Away from the face. Walking mass here changes how high the ball wants to leave and how much the head wants to twist on a mishit. Not a magic launch button.
