This is a spare hardware kit for all The Mix mixing heads.  It includes a 1/4-20 x 7/8" bolt, a 1/4" flat washer, and a 1/4" lock washer.  All hardware is 18-8 stainless steel. 

We reserve the right to substitute with a higher grade of stainless steel (e.g. 316), but will never utilize a grade lower than 18-8.
