Maypole M16 nuts, bolts and shakeproof washers in a 75mm length pair pack — designed for fitting flange-mount towballs to drop plates or thick towbar flanges where the standard 45mm bolt is too short. The shakeproof washers stop the nuts loosening under road vibration.

Sold as a pair to suit a standard 50mm flange-mount towball with a drop plate or extended flange. Made to British towing standards from a brand trusted by trailer and caravan owners across the UK for over 60 years.
