M12x1.25 Aluminum Lug Nuts 50mm Acorn Knurled Extended Open End 20pc
Twenty lightweight aluminum lug nuts with extended 50mm acorn design and knurled grip for easier hand-tightening. The M12x1.25 thread pitch matches most common wheel applications, and the open-end construction clears aftermarket wheels without clearance issues. Aluminum construction reduces unsprung weight compared to steel.

Frequently Asked Questions
Will these fit my wheels without the open-end design interfering?
The open-end design is specifically engineered to clear deeper wheels and custom offsets that deep acorn nuts would not fit. Test-fit before installing on your specific wheel; fitment depends on your rim's internal hub bore depth.
Do I need a torque wrench to install these, or can I just hand-tighten?
Hand-tightening to snug is fine for initial install, but you must torque to your vehicle's specification using a torque wrench afterward — refer to your service manual for exact torque specs. The knurled surface makes hand-snugging easier, but final torque is non-negotiable for safety.
Are these okay for daily driving or should I only use them on show cars?
Aluminum lug nuts are safe for daily driving when torqued correctly. Monitor them periodically — aluminum can relax slightly over time, so a quick retorque after your first 100 miles is smart practice.
