Milenco Locking Wheel Bolts – Motorhome 16" (Set of 4, M16) for Fiat Ducato / Peugeot Boxer Maxi, Thatcham Approved – 1922: Complete Review and Guide

Milenco Locking Wheel Bolts (Set of 4, M16) are precision-made, Thatcham and insurance approved bolts that resist the "hammer-on socket" method thieves sometimes use to remove standard bolts. This is the M16 (16mm) version, sized for Fiat Ducato and Peugeot Boxer motorhomes with 16" wheels on a Maxi (heavy-duty) chassis.

Choosing the right size

Check your bolt diameter before ordering: this set is M16. If your vehicle uses M14 bolts instead, Milenco's Set of 4 (product code 1915) is the correct fit, and if you need six bolts rather than four, product code 1939 is the M16 six-pack. Maxi chassis typically use 16mm bolts and Standard chassis typically use 14mm, though it's worth confirming your own vehicle's spec, particularly around the 2018 changeover.
