Truck Wheel Bolts & Studs Manufacturer
Wheel bolts and studs for trucks, buses and trailers: serrated round-head studs, T-head and flange head bolts pressed into the hub, double-ended studs, and dual-wheel bolts with inner and outer nuts. Class 10.9 or 12.9, made with their matching nuts to your OE number or sample.
Truck Wheel Bolt & Stud Types
Sorted by head type: the head and the serrated neck decide how the bolt sits in the hub. Class 10.9 or 12.9, made to your OE number or drawing.
Press-In Wheel Bolts & Studs
The serrated neck is pressed into the hub; the head shape stops the bolt from turning.
Serrated Round-Head Wheel Studs
Pressed into the hub. The mainstream type on North American trucks, for example M22 × 1.5 with a 32 or 33 mm flange nut.
T-Head (Clipped Head) Wheel Bolts
For European trucks and trailers. The head is clipped on one side so it locks against the hub and cannot turn.
Flange Head Wheel Bolts
A hex head with a flange and a serrated neck. Used on buses, light trucks and European models.
Dual-Wheel & Double-Ended
Bolts made with their inner and outer nuts, and studs threaded at both ends.
Wheel Bolts with Inner & Outer Nuts
For dual wheels on Japanese and Korean trucks such as Mitsubishi Fuso, Isuzu and Hino. Made with the inner and outer nuts; left-hand thread on the left side, right-hand on the right.
Double-Ended Studs
A stud with a center collar and a thread at each end.

How to Choose the Right Truck Wheel Bolt
A truck wheel bolt is pressed into the hub and stays there, so it has to match the hub and the wheel system exactly. Start with the axle, not the wheel.
ISO or JIS
Most European and Chinese trucks use the ISO hub-piloted system: the wheel is centered on the hub, and each serrated bolt carries one flange or thrust plate nut. Japanese trucks often use the JIS system: on dual rear wheels an inner cap nut clamps the inner wheel and an outer nut clamps the outer wheel, both on the same bolt.
Match the Hub
The serration diameter must press tightly into the hub flange, the head shape (T-head, D-head or round) must sit in its recess so the bolt cannot turn, and the length must suit the wheel and nut. All three follow the OE part, so the OE number or a sample is the fastest way to match.
Left-Hand and Right-Hand Threads
On JIS trucks the bolts on the left side usually have a left-hand thread and those on the right side a right-hand thread, so the nuts do not loosen as the wheels turn. Order both hands for a full axle.
Strength and Finish
Truck wheel bolts are made in class 10.9 or 12.9 from 40Cr or 35CrMo alloy steel, hardened to HRC 33–38 or 39–42. Common finishes are zinc plating, Dacromet zinc flake and black oxide, or plain.
Replace Bolt and Nut Together
A stretched bolt or a worn nut thread does not hold its clamp load. Replace them as a pair, tighten to the vehicle maker's torque and re-check after the first 50–100 km.

Truck Wheel Bolt Questions
What is the difference between ISO and JIS wheel bolts?
ISO (hub-piloted) wheels are centered on the hub and use a serrated bolt with one flange or thrust plate nut. JIS wheels on Japanese trucks use an inner cap nut and an outer nut on each bolt for dual rear wheels.
Why do some truck wheel bolts have a left-hand thread?
On JIS trucks the left-side bolts usually have a left-hand thread so the nuts do not loosen as the wheels turn. The right-side bolts have a right-hand thread.
What strength class and material are your truck wheel bolts?
Class 10.9 or 12.9, in 40Cr or 35CrMo alloy steel, hardened to HRC 33–38 for 10.9 and HRC 39–42 for 12.9.
Do you supply the nuts with the bolts?
Yes. We make each bolt together with its matching nuts, including inner and outer cap nuts for JIS dual wheels.
Can you match a bolt from an OE number or sample?
Yes. Send the OE number, a drawing or a sample, and we match thread, serration diameter, head shape, length and nuts.
