At M16 x 20mm, a very large thread meets a short body, with reinforced nylon and white polypropylene as the two material routes.

What changes between the M16 x 20mm materials?

Reinforced nylon gives a stiffer large-diameter bolt, while polypropylene keeps the fixing lighter and more resistant to moisture and many chemicals.
