Hi Eric,
You can of course never tell for sure when confronted with Medieval relics but in my opinion, and in all probability, these arrow shaped heads with the twisted hafts were used together with an incendiary mass.
The latter would probably stick more safely on a twisted haft.
Illustrated at the right-hand side of the attached photos is a crossbow bolt with its incendiary mass now missing.
Best,
Michael
