Example: .489 Core Thickness, drop last digit to read -48.
| Flush Head Styles | Non-Flush Head Styles |
| Note: For inspection, the actual sleeve length will be .010 to .015 shorter than the dash number called out. Example: -48 = .480, Actual Length = .465 to .470. |
Note: For inspection, the actual sleeve length will be .020 longer than the dash number called out. Example: -48 = .480, Actual Length = .500. |
Body Dash Number
1. Determine the Maximum Body Length (See Figs. 2) using the appropriate formula, below, based on Head Style.
| Flush Head Styles |
Non-Flush Head Styles |
| Overall Panel Thickness minus
Bottom Skin Thickness minus .010 Springback Factor. Example: .750 – Overall Panel Thickness– .020/.730 – Bottom Skin Thickness– .010/.720 – Springback |
Core Thickness plus Top Skin
Thickness minus .010 Springback Factor. Example: .690 – Core Thickness+.040/.730 – Top Skin Thickness– .010/.720 – |
2. Select Body Dash Number from the table below based on Maximum Body Length determined in Step 1; round down to next
lowest value.
Example: .720 Maximum Body Length = -70 Body Dash Number.
| Body Dash Number | M aximum Body Length |
| -30 | .335 |
| -40 | .350 |
| -50 | .450 |
| -60 | .550 |
