english in my drawings

CIAO from Italy!

I have a technical question about the correct english to use in my drawings.
My sector is about steel structures for bridges, plants, conveyor belts.

In an erection drawing we show all the elements have to arrange to erect the
part.
The detail of each single element is shown in other workshop drwaings.
In the erection drawing, beside, i put a list of components.

I ask you to correct my english in these titles for my tables (refer to the
explanation)

1) Workshop materials list (or bill? or list of...)
this is the title of the table in which we give ID, lenght, weight of every
single piece coming from the shop, eg. columns, beams, braces, etc.

2) Bolts list for workshop materials (or bill?)
this is the title of the table in which we give ID, quantity, unification,
treatment of bolts, eg. screw, nut, washers, expansion bolts, etc.

3) Commercial components list
list of piece coming from commerce, eg. bearing blocks, pullies, etc.

4) Bolts list for Commercial components
list of bolts for the components given on 3)

Thank you in advance

I think it is basically up to your company as long as you are consistent in
your labeling. I have seen them dome many different ways.
