Pin Gauge Kit M4

The Minus Pin Gauge Set is a high-precision tool specifically engineered for the meticulous examination of small internal diameters, bores, and holes across various manufacturing and quality assurance processes. What distinguishes this set is its intentional minus tolerance construction - each pin gauge is manufactured slightly undersized to ensure effortless insertion into target openings while still delivering exceptional measurement dependability.

Application:

Aperture size measurement

Purpose: Accurately measure the actual size of small holes and inner diameters to determine whether they meet design requirements.

Applicable scenarios: mechanical processing, mold manufacturing, precision parts inspection.

Verification of aperture tolerance

Purpose: To check whether the aperture is within the specified tolerance range (such as H7, H8, and other standard tolerances).

Applicable scenarios: Quality inspection of automotive components and aerospace precision parts.

steel pin gauge

Notes:

Instant testing and judgment, doubling efficiency

Support for "Go/No Go" fast detection logic - if the go gauge can be successfully inserted, it indicates that the aperture is ≥ the minimum limit size, and if the no go gauge cannot be inserted, it confirms that the aperture is ≤ the maximum limit size, without the need for complex readings or calculations. A single measurement only takes a few seconds, significantly improving batch detection efficiency.

Flexible adaptation

Provide a complete specification gradient from 0.011 to 1.000 inches (common increments of 0.001 inches), and some sets can also be customized with non-standard sizes to meet the needs of multiple industries and scenarios.
