Specified hole depth tolerance and effective depth tolerance
Hole depth tolerance and effective depth tolerance
You can specify a hole depth tolerance for a blind straight hole and an effective depth tolerance for a precision hole.
Minimum range of specifiable tolerances
| Tolerance range | |
|---|---|
| Automatic Quotation | 0.1 or more |
| Manual Quotation | 0.04≤Range＜0.1 |
Minimum range of specifiable tolerances for surface treatments, nitriding and heat treatment selections
| Automatic Quotation | Manual Quotation | Unable to quote | |
|---|---|---|---|
| Trivalent Chromate (clear) | 0.2 or more | 0.08≤Range＜0.2 | less than 0.08 |
| Trivalent Chromate (Black) | |||
| Hard Anodize (clear) | |||
| Hard Anodizing (White Matte Finish) | Unable to quote | ||
| Nitriding | |||
| Hardening | 0.2 or more | 0.08≤Range＜0.2 | less than 0.08 |
Hole types that can have hole depth and effective depth tolerance specified
| Hole types that can specify hole depth tolerance | Straight hole (blind only) | Slotted hole (blind only) | ||
|---|---|---|---|---|
| Hole types that can specify effective depth tolerance | Precision hole | |||
| Hole types that cannot specify either | Tapped | Insert | Pilot holes | countersunk hole |
Precautions
- If a hole depth tolerance is specified for a straight hole, the hole bottom shape is automatically specified as flat.
