A quartz banger or nail is designed to be used for smoking waxes, oils or resins instead of a cone piece which is designed to be used with flower.  

Quartz bangers and nails come in different shapes and sizes but all serve the same function, to turn plant extracts into vapor. They are best used with a purpose designed dab rig or banger hanger, but can also be used in any small glass bong.  

We have all manner of quartz bangers and nails here, full weld, regular weld, terp slurpers, control towers, gavel style, blenders in 45 degree for beaker bongs or 90 degree for most dab rigs.

OzBongs were the first to import and sell dab rigs, nails and other dabbing accessories in Australia in the early 2010's. The products have evolved over that time to be more practical and simpler. 

If you are looking for dabbing accessories like marbles, carb caps and dabbers etc, you can find them here.
