💡 How do I read a micrometer or caliper correctly?

Good technique matters as much as the tool.

• Clean the part and measuring faces before every reading.
• Use light, steady pressure or the ratchet stop.
• Zero the tool and recheck it against a standard.

Pick up the Starrett Penetrator and keep your jobs moving.
