With the UK leaving the European Union on 31st December 2020 and no firm
deal yet ratified, we would like to reassure all of our customers in the EU that
it will be business as usual in 2021. From 1st January we will no longer charge
Tax (VAT) on orders shipped into the EU and instead our couriers will make the
customs entry on our behalf and advise of local Tax and duty prior to delivery.
If you are an EU registered business, we would request you advise us of your EORI number in advance to avoid import problems/delays
British Association screw threads, or BA screw threads, are a largely obsolete set of small screw threads, the largest being 0BA at 6 mm diameter. They were used by Lucas in many of the instruments and also found in the MG early models in handles, windscreens and many of the chrome items.
UNC and UNF are symbols of Unified Screw Thread Series
The Unified Thread Series was agreed on by the United States, Great Britain and Canada in 1949 to obtain interchangeability. Recently, modifications have been made to the original 1949 specifications for ease of use.
The Unified Thread Series is classified into coarse threads, fine threads and extra fine threads much like Metric screw threads are.
UNC: Is the symbol for Unified coarse pitch threads.
UNF: Is the symbol for Unified fine pitch threads.
