White Knight M12x1.50 Six-Spline Lug Nuts 20-Pack — Black Chrome, 0.80" Small-Diameter Seat, Keyed

White Knight 3807BK-20AM is a 20-pack of black chrome, M12x1.50 six-spline spline acorn lug nuts with a 0.80" small-diameter seating, designed for select aftermarket wheels and supplied with a matching key adapter option.

These lug nuts are built for aftermarket wheels that require a smaller 0.80" diameter seat and a six-spline drive. Constructed from cold-forged carbon steel with a black chrome finish, they combine strength, corrosion resistance and a clean appearance that resists color stripping more effectively than painted finishes. They fasten with a 60° conical seating profile and work with the specified spline key adapter (replacement adapter B07PWYQXVR/3800) for secure installation.

Are these lug nuts compatible with my aftermarket wheels?

Compatibility depends on several wheel and vehicle measurements: thread pitch, seat diameter, seating angle and overall nut length. These nuts use M12x1.50 threads, a 0.80" small-diameter seat, and a 60° conical seat, so they only fit wheels designed for those specifications.

• Thread pitch: M12 x 1.50
• Seat diameter: 0.80" (small-diameter seat)
• Seating angle: 60° conical
• Overall height: 1.37"; spline acorn style

How do I install and remove the six-spline White Knight lug nuts?

These lug nuts require the six-spline key adapter (sold separately as B07PWYQXVR / White Knight 3800) to engage the internal spline pattern. Use a torque wrench to tighten to the vehicle and wheel manufacturer’s specified torque; avoid using only an impact wrench to prevent over-torquing or damage to the wheel.

• Use the six-spline key adapter for installation/removal
• Tighten to manufacturer-specified torque with a torque wrench
• Check fitment and alignment before final torque
• Re-torque after initial 50–100 miles of driving

What are the construction and finish benefits of the black chrome White Knight lug nuts?

Cold-forged carbon steel provides high tensile strength and durability under load. The black chrome plating offers improved resistance to color stripping compared with factory paint, keeping the nuts looking sharp while protecting the steel substrate from corrosion.

• Material: cold-forged carbon steel for strength
• Finish: black chrome to resist color loss and corrosion
• Drive style: 6-spline for secure engagement and fast installation
• Tested to industry standards for dependable performance
