Sposuit M12x1.25 Black Spline Lug Nuts 24pc — 19mm Drive, 60° Conical, Closed-End

Sposuit 24-piece M12x1.25 black spline lug nuts are a one-piece, closed-end replacement set designed for many Nissan trucks and SUVs that need durable, corrosion-resistant wheel fasteners.

These lug nuts are engineered as a direct-fit aftermarket option for numerous Nissan models from the late 1980s through the 2020s, providing a finished black appearance, a conical 60° seat, and a spline-style external shape paired with a 19mm (17mm hex inner) drive. Manufactured by Sposuit using cold forging, heat treatment and triple chrome plating, the set aims to resist wear and corrosion while delivering consistent torque and a clean closed-end look for alloy or steel wheels. Before ordering, check your vehicle's year, wheel seat type and thread pitch to confirm compatibility.

Will these lug nuts fit my Nissan model?

Compatibility depends on hub thread pitch, seat angle and the wheel's lug nut engagement depth. This Sposuit set is M12x1.25 thread pitch with a 60° conical seat and is intended for certain Nissan Frontier, Titan (non-XD), Pathfinder and Xterra years; detailed fit lists are provided in product images. Always measure or verify your vehicle's factory lug specifications before purchase to ensure a proper fit.

• M12x1.25 thread pitch suitable for specified Nissan models.
• 60° conical seat matches many OEM wheel designs.
• Closed-end design limits dirt and moisture intrusion.
• Confirm wheel lug hole diameter and engagement depth on your wheels.

How strong and corrosion-resistant are these lug nuts?

Sposuit manufactures these nuts with cold forging and heat treatment to increase tensile strength and toughness. A triple chrome plating finish is applied to improve resistance to rust and surface wear, while precision machining and factory testing help maintain secure fitment under typical driving conditions.

• Cold-forged, heat-treated steel for added strength.
• Triple chrome plating for enhanced corrosion protection.
• One-piece construction reduces potential failure points.
• Factory-tested for consistent thread and seat accuracy.

What are the dimensions and design features of this set?

The kit includes 24 black closed-end spline lug nuts plus one heavy-duty socket for installation. Each nut measures approximately 35mm (1.38") tall with an internal 17mm hex drive opening and a 20mm outer width; the closed end helps prevent contamination of the stud threads and gives a finished look.

• 24-piece set with one installation socket included.
• Overall height: ~35mm (1.38").
• Internal hex: 17mm; outer width: ~20mm (0.78").
• Closed-end, one-piece spline nut with 60° conical seat.

How should I install and maintain these lug nuts?

Use the supplied heavy-duty socket or an appropriate spline tool to thread each nut by hand first, then torque to the vehicle manufacturer's specification with a calibrated torque wrench. Periodic inspection for tightness and surface condition is recommended; avoid impact wrenches for final seating unless the torque is verified after installation.

• Hand-start each nut before torqueing to avoid cross-threading.
• Tighten to the vehicle OEM torque spec with a torque wrench.
• Inspect for corrosion or damage during routine service.
• Re-check torque after initial road use and at regular intervals.

Who is this for: This Sposuit lug nut set is aimed at Nissan owners and mechanics seeking a full 24-piece replacement with a sleek closed-end black finish, especially those restoring, upgrading or replacing worn aftermarket or OEM wheel fasteners on compatible Frontier, Titan (non-XD), Pathfinder and Xterra models. It's also suitable for fleet and DIY users who want a robust, plated one-piece nut with a matching spline socket included. If you need an exact fit, confirm thread pitch, seat angle and wheel compatibility before ordering to ensure correct fitment and safe installation.
