Maypole M16 nuts, bolts and shakeproof washers in a 90mm length pair pack — designed for fitting flange-mount towballs to deep drop plates or stacked spacer setups where extra bolt length is needed. Shakeproof washers prevent the nuts loosening under towing vibration.

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