Profiled/Lipped Bolt to Fit Original Amal Clip Fitting Inlet Rings (i.e. 276/289 and TT/RN Clip)

This listing is for the distiinctive shouldered and profiled hex head bolt that fitted to the Inlet ring on Amal Type 76/276 and Type 86/286 Stub Fitting Carburettors - it having the important function of ensuring the carb was securly located to the inlet stub.  These are CNC manufactured by us to the original design in stainless steel and the heads lightly polished.

They were also used on Competition TT/RN clip fitting carburettors.

Price is each.

We have replicated the original design of this small bolt - which as you can see in the photos - has a distinctive grooved shoulder - so that the actual hex of the bolt is held out from the inlet clip - to allow for the best possible tightening with a ring spanner.  This small detail may seem incongrous - but when you realise that it is this bolt that correctly tightens the whole carburettor to the inlet stub - and that on many motorcycles, the head of this bolt was not easy to get good spanner access to - it makes you realise how important a job it has to do!

Because of this difficutl access, and because of the engine vibration and weight of the carb - it is not uncommon to find that the ''Stub' fitting type carburettors often have this orignal bolt badly 'chewed' and the hex faces badly rounded.  This of course means the carb is far more likely to not get fully tightened - often leading to wear of the carb bore, and meaning air can enter from the stub and affect the running of the engine.

As well as the distinctive sthape and profile of the bolt - we CNC mill the hex head to the correct imperial spanner size of  1/8" Whit (we mill this head, as it is becoming increasingly difficult to obtain it in stainless steel), which gives a very crisp finish - important, as it is often this hex head that suffers on original carbs - as they are often overtightened with use.   We emphasize this - because having personally experienced the annoyance at having to try and continually tighten an original bolt, where years of abuse has 'Rounded' the original head of a Type 276 carb, it is a pleasure to fit a bolt that allows a close fit of the correct spanner!

As a final design point - we have also replicated the opposite threaded end on these small bolts - which was rounded, as it protruded from the threaded end of the ring - presumably to avoid it catching on cloth's when the owner cleaned the bike.
