Description
Product Overview
Flycle’s Chrome Closed‑End Lug Nuts are engineered for drivers who demand reliable wheel fastening without compromising style. Each nut features a 14 mm x 1.5 mm metric thread, a conical 60° seat, and a lock‑type design that resists loosening under heavy braking and cornering forces. The nuts are cold‑forged from SCM 435 alloy steel, then heat‑treated for enhanced tensile strength, and finally polished to a mirror‑like chrome finish that resists rust and adds a sleek look to any wheel.
Usage
These lug nuts are suited for passenger cars, light trucks, and SUVs equipped with standard 14 mm wheel studs. They excel in everyday commuting, weekend road trips, and spirited driving where wheel torque stability is critical. Install them on wheels that require a conical 60° seat; they are not compatible with mag, ball, or round seats.

FAQ
What wheel studs are compatible with these lug nuts?
They fit 14 mm diameter studs with a 1.5 mm thread pitch and require a conical 60° seat. They are not suitable for mag, ball, or round seat wheels.
Can I use these nuts on alloy wheels?
Yes, the chrome‑plated finish is safe for both steel and alloy wheels, providing a corrosion‑resistant seal that protects the wheel surface.
Do I need a special tool to install them?
Each package includes a socket key that matches the external hex drive. Standard torque wrenches are recommended to achieve the manufacturer‑specified torque values.
How does the lock feature work?
The lock design incorporates a slight deformation on the nut’s outer surface that creates a friction fit with the wheel stud, reducing the chance of self‑loosening during vigorous driving.
What is the warranty period?
Flycle offers a 12‑month warranty covering material defects and provides technical support for installation queries.
