Parts for your 2019 Suzuki Splash-Wheel studs nuts

Are wheel studs and nuts used on a 2019 Suzuki Splash?

Short answer: no, wheel studs and nuts aren’t used on the 2019 Suzuki Splash. Technical references including the factory workshop information for the Suzuki Splash/Opel-Vauxhall Agila B platform, along with independent fitment datasets (e.g., Autodata/HaynesPro-style wheel fixing specs and well-known wheel fitment databases), specify a 4×100 PCD with M12×1.5 lug bolts that screw directly into the hub. Those sources consistently list the fastener type as “bolt”, not “stud and nut”.

Why’s that the case? The Splash sold in this era is built on a European co-developed platform with Opel/Vauxhall, and like many European small cars, it uses hub-threaded wheel bolts rather than pressed-in studs with separate nuts. That design choice is purely an engineering preference, not a downgrade—just a different way to clamp the wheel securely to the hub.

• Platform DNA: The Splash shares hardware conventions with the Opel/Vauxhall Agila B, which uses lug bolts from the factory.
• Manufacturing norm: European mass production commonly favours lug bolts, Japanese domestic models more often use studs and nuts.
• Service implications: With bolts, the hub carries the threads, the wheel is located hub-centrically on the spigot (centre bore), then clamped by the bolts.

For servicing and tyre rotations on a 2019 Suzuki Splash, that means handling wheel bolts rather than nuts. A few friendly pointers still apply: clean the mating faces (hub and wheel) so the wheel sits flat, start each bolt by hand to avoid cross-threading, snug them up in a star pattern, then final-torque with a calibrated torque wrench to the specification on the vehicle’s placard or owner’s manual. Avoid lubricants on the threads unless the service documentation explicitly allows it, because lube changes clamping force for a given torque.

If someone really wants studs and nuts, aftermarket conversion kits exist that thread into the hub in place of bolts. That said, OE-spec lug bolts are the correct, proven setup for this model, and changing the fixing method may introduce clearance, legality, or insurance considerations—best checked with a licensed mechanic.

Question: Does the 2019 Suzuki Splash use wheel studs and nuts?

No. It uses M12×1.5 lug bolts that screw into the hub, as specified in Splash/Agila B workshop data and widely used fitment references for the 4×100 platform.

Question: Can the Splash be converted to studs and nuts?

It can, using stud conversion kits that thread into the hub, but it’s not generally recommended. Fitment (thread depth, brake clearance), certification, and insurance implications should be checked with a licensed mechanic before committing.

Question: What size and torque should be used on the Splash’s wheel bolts?

The hex head is typically 17 mm on OE-style bolts, but always verify what’s fitted to the car. For tightening, use the torque value on the vehicle’s placard or in the owner’s manual, small cars in this class are commonly around the 100 Nm mark, but the manufacturer’s spec takes priority.
