Trev's Vintage Machine Shop

This is a set of replacement extra long stainless steel carburetor studs with stainless steel nuts and washers to fit many British-made classic motorcycles including BSA A10 & A7 with alloy cylinder head. I also have studs for iron cylinder heads, see my other listings for details.

These are 60mm long overall to accommodate a 30-32mm spacer with monobloc carb. Threaded 5/16 BSW and 5/16 BSCy, machine cut threads. Supplied with standard 5/16 hex nuts (1/4 Whitworth spanner size).

These studs are manufactured in our own workshop here in the UK using high quality stainless steel, so they are an upgrade over the original parts that were only made from plain steel. They are far superior to cheaper, lower quality studs that tend to be made from threaded rod or long grub screws.

It contains 2 new studs, 2 stainless steel nuts and 2 stainless steel washers as shown in the picture. Please remember to apply a smear of copper grease or similar to the threads during assembly. All items are dispatched quickly via Royal Mail 2nd Class, with 1st Class available at extra cost.

Not what you want? Return the studs unused for a refund.

Please check my feedback, I try very hard to get things right. Any problems at all just let me know.

Free postage to UK mainland only. If you have any questions then please ask.
