What it is
The Sime 2016020 is an M4 locked nut supplied for Sime gas boilers. It is a threaded fastener used to secure components within the appliance assembly. It is listed under screws, nuts, bolts and clips in the Sime gas boiler spares range.
Signs this part needs replacing
- The nut is missing from its fixing point, leaving the component it secures loose.
- Threads are stripped or cross-threaded so the nut will not tighten to torque.
- Corrosion or scale has built up on the nut, preventing clean removal or refitting.
- The nut has worked loose through vibration and no longer holds the assembly secure.
- The locking feature has lost its grip and the nut backs off after tightening.
Before you order
- Confirm the thread size required is M4 before ordering.
- Check your appliance model against the fitment list above.
- Inspect the old nut and its fixing point for thread damage that may need attention.
- Confirm how many nuts are needed for the repair.
