Where articles require free movement of parts, e.g. drop handles, hinges, shackles, shafts or spindles:
- A radial clearance should be applied to the part to allow for the galvanized coating thickness. Recommended minimum radial clearances are shown in Table 5.
- Parts need to be disassembled and galvanized separately.
Recommended minimum radial clearance before galvanizing
|Shaft or spindle size (mm)||Minimum radial clearance (mm)|
|≥ Ø10 to ≤ Ø30||2.0|
Note: Some fettling may be required after galvanizing to enable parts to be free moving.
