Wire grommet selection requires the mounting-hole size, panel thickness and cable dimensions. A nominal diameter or eyelet size number does not define all of these measurements.
Unit conversions
One inch equals exactly 25.4 mm. The examples below are conversions only, not a catalogue of available parts or a universal grommet numbering standard.
| Inches | Millimeters |
|---|---|
| 5/16 | 7.9375 |
| 3/8 | 9.525 |
| 1-7/16 | 36.5125 |
Use the part drawing
Identify whether a stated dimension is the bore, mounting hole or flange outside diameter. Preserve the specified tolerances when converting units; do not round a value and assume a nearby metric part is interchangeable.
Confirm the profile, compound and quality requirements before ordering. Use a drawing or existing sample to request a custom part when the catalogue does not provide a suitable match.
