Professional Precision Made 6pc BA Chrome Vanadium Spanner Set in Pouch 0 - 11OBA SP146 - NEW
British Association or (BA) screw threads are a set of small screw threads, the largest in this set being 0BA and the smallest being at 11BA.
They are very hard to come by but are still widely used for miniature instruments and modelling.
These are probably the most "scientific" design of screw which need a precision made spanner set to undue and tighten.
Ideal for the hobbyist, model maker and small instrument worker.
Satin polished Chrome Vanadium heat treated steel for extra durability.
