AUTOPTIM M10x1.25 ATV Lug Nuts - 16 Pc Chrome Open-End, 17mm Hex & 60° Seat

AUTOPTIM M10x1.25 open-end chrome lug nuts are a 16-piece, cold-forged set engineered to fit many ATV wheels with a 60° seat for reliable fastening and corrosion resistance.

These lug nuts are made for riders who need a durable, corrosion-resistant fastener solution for ATVs like Can-Am, Polaris, Honda and Kawasaki models. Cold-forged and heat-treated steel with a triple chrome finish gives a balance of strength and appearance, while the open-end design allows use with extended studs. The pack includes 16 M10x1.25 nuts sized for a 17 mm hex, offering straightforward replacement or upgrade in one purchase.

Will these lug nuts fit my ATV wheel?

Compatibility depends on stud thread and seat angle: these are M10x1.25 threads with a 60° conical seat, common on many ATVs. Confirm your wheel studs match the M10x1.25 pitch and use a 60° seat; this ensures correct contact and clamping. If your vehicle uses larger threads or a different seat style, choose a matching nut instead.

• Thread size: M10 x 1.25 (metric fine)
• Seat: 60° conical
• Hex: 17 mm (0.62") wrench size
• Typical fit: Can-Am, Polaris Sportsman, Honda TRX, Kawasaki KAF/KVF models

How durable and rust-resistant are these lug nuts?

These nuts are cold-forged and heat-treated for improved tensile strength and fatigue resistance. A triple chrome plating enhances corrosion protection and surface hardness; AUTOPTIM also performs a 72-hour salt-spray test during production to validate anti-corrosion performance. For routine off-road usage and exposure to moisture, the finish helps extend service life compared with uncoated steel.

• Manufacturing: cold-forged, heat-treated steel
• Finish: triple chrome plating for corrosion resistance
• Quality check: 72-hour salt-spray trial simulated
• Benefit: longer service life and reduced rusting

What does the open-end style mean and why choose it?

Open-end lug nuts are hollow at the back to clear longer wheel studs or aftermarket spacers, allowing full stud engagement and proper clamping. The one-piece design reduces the number of components to manage and simplifies installation. This style is particularly useful when you have extended studs or want a tight fit without trimming studs.

• Design: one-piece open-end construction
• Use case: compatible with extended studs and spacers
• Installation: allows full stud thread engagement
• Advantage: saves time and reduces parts complexity

What size and hardware details should I expect in the pack?

The set contains sixteen M10x1.25 lug nuts sized for a 17 mm hex key, with overall dimensions suited for most ATV wheel wells. Overall height and width are compact to fit tight wheel pockets while providing sufficient thread length for secure torque. AUTOPTIM includes customer support for questions before or after purchase.

• Quantity: 16 lug nuts per pack
• Overall height: approximately 15.7 mm (0.62")
• Width: about 20 mm (0.8")
• Hex drive: 17 mm wrench compatibility

Who is this for: Riders and DIY mechanics who own ATVs or side-by-sides that require M10x1.25 threads and a 60° seat, and who want a corrosion-resistant, open-end lug nut option in a full 16-piece set. Ideal for owners replacing worn hardware, fitting aftermarket wheels with extended studs, or upgrading from lower-grade nuts for improved durability and appearance.
