Tubular commonly used button is divided into three types are EU, NU and New Vam. These three types of buckle can be found in the tool shop, EU and NU alone from the buckle appearance is very difficult to distinguish, are triangular buckle, but from the entire string can be easily distinguished, that is EU said the outer thick NU means no outer thickening. New Vam is actually a trapezoidal buckle (buckle rectangular cross section), but also without thickened, so it is also very easy to distinguish.
1) EU (External upset) thickened outside
EU deduction is a thick tube type deduction. In the workshop on the understanding of the variable buckle adapter will find three EU-related biano logo. The External Upset End (EUE) indicates the outer thickened end, the External Upset Pin (EUP) indicates the outer thickened buckle, and the External Upset Box (EUB) indicates the outer thickened buckle.
2) NU (Non-upset) No outer thickening
NU means that there is no thick hose connector. In addition there is no outer thickening and EU generally there is a difference between the NU generally 10 buckles per inch, EU generally 8 buckles per inch. Where NUE means non-thickened end or end non-thickened.
3) New VAM
This buckle is characterized by buckling cross-section is basically rectangular, pitch equal intervals, taper is not large, no outer thick. See at the end of the shop's production sleeve.
