10 x M2.5 Stainless Steel nuts for Lampwork Ring Toppers – these nuts are compatible with M25 Interchangeable jewellery .
These nuts have a sealed top so the glass cannot enter the screw thread, also the hexagonal head is wider than the nut shaft ensuring the nut will not fall out of the glass when in use.
These nuts fit our 21 mm cabochons and 14mm cabochon mandrels, they sit over the nubble in the middle and should be applied when the bead release is wet. The bead release ensures the nut stays in place whilst the glass is applied.
These are the nuts I use with our cab mandrels for all my ring toppers and interchangeable cabochons.
