Are the specs and hearder texts fixed values? If so you can try something like this:

with CTE as (
select PartNumber, cast(Spec as varchar) as tcolumn
from yourtable
union all
select PartNumber, HeaderText as tcolumn
from yourtable
)
 
select Partnumber,
	[100] as Spec1,
	[60] as Spec2,
	...
from
(select * from CTE) o
pivot (max(tcolumn) for tcolumn in ([100], [60], [0.017], ... [VDSS,max,(V)]...)p

What about something like this then?

with CTE as (
select PartNumber, cast(Spec as varchar) as tcolumn, 'spec' + cast(row_number() over (partition by PartNumber order by PartNumber) as varchar) as rn
from yourtable
union all
select PartNumber, cast(HeaderText) as tcolumn, 'header' + cast(row_number() over (partition by PartNumber order by PartNumber) as varchar) as rn
from yourtable
)
 
select 	PartNumber,
	[spec1],
	[spec2],
	...
	[header1],
	...
from
(select * from CTE) o
pivot (max(tcolumn) for rn in ([spec1], [spec2], .... , [header1], [header2], ....)p
