Body and Sleeve Dash Number Selection
Sleeve Dash Number
Round down to the nearest hundredth of an inch of the panel core thickness (See Figs. 1).
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 Factor =- Maximum Body Length |
Core Thickness plus Top Skin
Thickness minus .010 Springback Factor. Example: .690 – Core Thickness +.040 /.730 – Top Skin Thickness – .010/.720 – Springback Factor = – Maximum Body Length |
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 |
| -70 | .650 |
| -80 | .750 |
| -90 | .850 |
| -100 | .950 |
| -110 | 1.050 |
| -120 | 1.150 |
| -130 | 1.250 |
| -140 | 1.350 |
| -150 | 1.450 |
