Milenco Locking Wheel Bolts – 16 mm – Fiat Ducato/Peugeot Boxer 16" Maxi Chassis (2007–2015, 2016+) – Set of 6 with Key – Thatcham & Insurance Approved (SKU 1939)

Cost-efficient yet precision-made, Milenco Locking Wheel Bolts protect your wheels from theft. Often called “locking wheel nuts”, these are technically wheel bolts with a high-security coded pattern that cannot be removed by the usual “hammer-on a socket” method. Tested and Thatcham approved and insurance approved, they’re built for year-round touring and everyday peace of mind.
Pack size: 6 bolts + 1 key (ideal for vehicles with six wheels, twin-rear/tag-axle set-ups, or to secure four wheels plus spares). SKU: 1939.
