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.

Selection guide (measure before purchase)
If your bolt diameter is 14 mm → choose SKU 1915
If your bolt diameter is 16 mm → choose SKU 1922 (4-pack) or SKU 1939 (6-pack, this item)
Note: Fiat/Citroën/Peugeot use different bolt sizes depending on wheel size and chassis duty.
Pre-2018: check wheel size (15" vs 16").
