Stainless steel spoke

Example 7a: Stainless steel spoke
Imitation
  • Metric thread (M3.5) with reduction from 3.42 mm to 3.13 mm
  • Unpolished surface – wire is rough
  • Dents evident around the hook
  • Rear head angle of the spoke head is wrong
  • Spoke head is not fully concentric
  • Upper flank diameter exceeded and therefore not to gauge
  • Upper dimensional limit of the external diameter exceeded at the thread
  • Thread not uniform in shape and too short
  • Spoke nipple wobbles on the spoke – a first sign of poor gauge accuracy
  • The nipple supplied can be turned on the spoke – poor gauge accuracy
  • Go/no-go gauge almost falls through the nipple
  • Reproduction of the cloverleaf logo tends to merely suggest the outline
