+ Tool use: **web_search** • Searched web `6-32 Phillips flat head screw head diameter dimensions` • **1** results + +| Title | URL | Chunk | +|-------|-----|-------| +| Web Search Results | | The head size of a screw is primarily determined by its head type and diameter, not its length. Both screws you've mentioned are #6-32, indicating they have the same diameter and thread pitch. The difference in length (6 inches vs. 5 inches) doesn't affect the head size.

A #6-32 Phillips flat head screw typically has a head diameter ranging from 0.238 inches to 0.262 inches. ([lhdottie.com](https://lhdottie.com/6-32-flat-head-squarephillips/fmdd6321?utm_source=openai))

Hard drive screws are often #6-32 pan head screws, which generally have a head diameter of approximately 0.294 inches. ([digikey.com](https://www.digikey.com/en/products/detail/apm-hexseal/R6-32X5-16-2701/1159355?utm_source=openai))

Therefore, the head of a #6-32 Phillips flat head screw is smaller in diameter compared to a #6-32 pan head screw, with the flat head being about 0.032 to 0.056 inches smaller. | + +

+ Tool use: **web_search** • Searched web `6-32 hard drive screw head diameter dimensions` • **1** results + +| Title | URL | Chunk | +|-------|-----|-------| +| Web Search Results | | The head diameter of a #6-32 Phillips flat head machine screw typically ranges from 0.238 inches to 0.262 inches. ([lhdottie.com](https://lhdottie.com/6-32-flat-head-squarephillips/fmdd6321?utm_source=openai)) Flat head screws are designed to sit flush with the surface, so their head height is minimal, around 0.083 inches.

In contrast, hard drive screws often use a #6-32 thread size with a pan head design. For example, a #6-32x5/16" pan head Phillips machine screw has a head diameter of approximately 0.22 inches and a head height of about 0.09 inches. ([walmart.com](https://www.walmart.com/ip/3945824417?utm_source=openai))

Comparing the two:

- **Head Diameter**: The flat head screw's diameter (0.238" to 0.262") is slightly larger than the pan head screw's diameter (approximately 0.22").

- **Head Height**: The flat head screw's height (0.083") is slightly less than the pan head screw's height (0.09").

Therefore, the flat head screw has a marginally larger head diameter but a slightly shorter head height compared to the pan head screw. | + +
