MIKKUPPA 9/16-18 Lug Nuts for Dodge & Ford Trucks — Chrome Silver, 60° Conical Seat, Closed-End

MIKKUPPA 9/16-18 lug nuts are durable, closed-end bulge-style replacement fasteners engineered for select Dodge, Ford and Hummer wheels.

These lug nuts offer a direct-fit option when factory hardware needs replacement or when upgrading to aftermarket wheels that require a 9/16-18 thread and 60° conical seat. Built from cold-forged, heat-treated steel and finished in chrome-like silver, the nuts combine corrosion resistance with a one-piece construction for consistent torque and long-term reliability.

Which vehicles are compatible with MIKKUPPA 9/16-18 lug nuts?

These lug nuts are designed to match the thread, seat angle and length used on many older Dodge and Ford trucks plus some Hummer models. Confirm your vehicle’s thread size and seat type before purchasing to ensure a correct fit.

• Compatible Dodge models: Ram 1500 (2002–2010), Ram 2500/3500 series and related van years listed.
• Compatible Ford models: F-250 (1984–1997) and F-350 (1985–1997).
• Other fitment: Hummer H1 2002–2006 (excluding 2005).
• Specification check: 9/16-18 thread, 60° conical seat required on wheel.

How are these lug nuts built to resist corrosion and wear?

MIKKUPPA applies a thick, integrated coating that is bonded to the metal using infrared drying methods, which reduces the chance of flaking. The nuts also undergo an extended salt spray evaluation to verify resistance to oxidation and surface degradation.

• Cold-forged, heat-treated steel core for strength under torque.
• Integrated paint finish to minimize peeling and rust formation.
• Salt spray tested to improve long-term exterior durability.
• Closed-end design keeps threads protected from contaminants.

What are the key dimensions and installation details?

These lug nuts are longer than many standard nuts, providing secure engagement on deeper studs used by some trucks and aftermarket wheels. They require a 3/4" (19mm) hex socket for tightening and feature a 60° tapered seat to match compatible wheels.

• Thread: 9/16-18; Seat: 60° conical (bulge style closed end).
• Overall length: 48 mm (approximately 1.92").
• Hex size: 3/4" (19 mm); nut body width ~23 mm (0.9").
• Chrome-like silver finish for visual consistency with many wheel styles.

Do these lug nuts require any special maintenance or care?

No specialized maintenance is needed beyond routine wheel checks. Periodic inspection for torque, surface damage or corrosion will keep wheels secure; replace any nut that shows thread damage or significant coating loss.

• Check torque after first 50–100 miles following installation.
• Inspect threads and finish during tire rotations or seasonal checks.
• If contaminants accumulate, clean gently and re-torque to spec.
• Replace any nuts with stripped threads or significant coating failure.

Who is this for: MIKKUPPA 9/16-18 lug nuts are aimed at owners of older Dodge and Ford trucks, Hummer H1 owners with compatible wheel seats, and anyone fitting aftermarket wheels that call for 9/16-18 closed-end bulge nuts. They suit DIY mechanics, shops replacing worn or corroded lug hardware, and drivers who want a one-piece, corrosion-resistant nut that matches OEM-style seating and delivers consistent torque performance.
