In automotive checking fixtures, the checking pin is a direct contact component that determines whether dimensional inspection results are accurate, repeatable, and trustworthy.
From a user’s perspective, a checking pin must provide precise positioning, smooth operation, and long-term stability, even under high-frequency inspection conditions.

Gooding manufactures precision checking pins specifically for automotive checking and inspection fixtures, ensuring reliable measurement results throughout the entire fixture life cycle.

Why Checking Pins Are Critical in Real Inspection Use

In daily inspection operations, checking pins are used to:

• Verify hole position and size

• Check part alignment and assembly accuracy

• Serve as functional references in dimensional inspection

• Work together with testing bushes and guide bushings

For users, the requirement is very clear:

A checking pin must always indicate the true condition of the part — no deviation, no drift.

Gooding checking pins are engineered to meet this exact expectation.
