Stainless Sump Bolt Kit for Vauxhall Z20 Engine
Replacement set of bolts for the Z20 engine's sump.
Whilst mainly being a better looks thing, these bolts are also a bit less liable to rounding, especially the little ones in the lower steel part of the pan. They are also nice and clean, and won't shed any zinc coatings, due to not having any, into your oil.
This is for a full set of bolts to do the entire sump, upper and lower.
These are a graded stainless bolt with intergarted flange head , this provides a nicer spread of the load into the sump mounting faces when fastening them together.
