Description
Calculate counterbore recess margin relative to a supplied fastener-head height.
Product geometry depends on reference surfaces, mating dimensions, signed offsets, compression assumptions and material behavior. A clearance comparison or nominal engagement depth describes a limited scalar relation. Physical fit, ergonomics, sealing, strength and electrical compatibility need the complete product and its verified conditions.
Calculate counterbore recess margin relative to a supplied fastener-head height.
When to use this tool
Use Fastener Counterbore Depth Head Margin when you already have counterboreDepth, headHeight and need to calculate counterbore recess margin relative to a supplied fastener-head height.
How to use the tool and how it works
- Enter counterboreDepth, headHeight. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read recessMargin. Use the output convention below.
Require nonnegative depths/heights; return counterboreDepth-headHeight.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| counterboreDepth | Counterbore Depth | Required. Finite number; minimum 0. |
| headHeight | Head Height | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| recessMargin | Recess Margin | Required. Finite number. |

}Limitations and assumptions
- Negative margins are retained; no fastener geometry, strength, tool access or safe installation is checked.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Inspect actual component specifications and a complete dimensioned assembly for design decisions. Add material, loading, tolerance and operating-condition analysis when a local gap, radius ratio or supplied compression fraction cannot establish performance.
