Milenco Locking Wheel Bolts – Motorhome 15" (Set of 4, M14) for Fiat Ducato / Peugeot Boxer Non-Maxi – Thatcham Approved (1915): Features, Benefits and Installation

Milenco Locking Wheel Bolts (Set of 4, M14) are precision-engineered, Thatcham and insurance approved bolts that resist the "hammer-on socket" method thieves sometimes use to remove standard bolts. This M14 set fits Peugeot Boxer and Fiat Ducato motorhomes with 15" wheels (2007–2015), and all non-Maxi chassis models with 15" or 16" wheels from 2016 onwards.

Choosing the right size

Measure your existing bolt diameter before ordering: this set is for M14. If your vehicle uses M16 bolts instead, Milenco offers a Set of 4 (product code 1922) or a Set of 6 (product code 1939). As a rough guide, Maxi (heavy-duty) chassis typically use M16, while Standard chassis typically use M14 — but always confirm your own vehicle's specification, especially on pre- and post-2018 models where sizing can vary.

What you get
