Question by: Harold C on Dec 20, 2025, 12:00 PM
what material is this socket made out of, and will it hold up in a rough industrial setup?
Answer by: Customer Support on Dec 21, 2025, 6:08 PM
Carbon steel construction on this one, so it's built to handle demanding conditions without giving out on you. For heavy industrial use, that's generally what you want in a hydraulic fitting component. It's not a lightweight or decorative part by any means.
