KFFKFF 14-Piece 1/4" Drive Impact Socket Set - Metric 4-15mm Deep Sockets - Durable Cr-Mo Steel for Automotive Repairs - Clear Size Markings - Sturdy Design with Organizer

This impact socket set is crafted from durable industrial-grade alloy steel and has undergone specialized heat treatment processes, including high-temperature quenching and low-temperature forging, to achieve a hardness rating of HRC42-48.

This versatile set is designed for use with electric wrenches, impact wrenches, ratchet wrenches, rod benders, and other tools, making it suitable for automotive repairs, equipment assembly, industrial production, power system checks, and various other applications.

The hexagonal socket structure minimizes contact between the nut and edges during use, reducing friction and wear. It is designed to endure high impact forces and efficiently loosen bolts.

Crafted with laser etching and rolling techniques, the oversized size markings on the sockets are designed for easy visibility, even in different lighting environments. These markings are also durable and resistant to fading over time.

The reinforced split-case design enhances durability and minimizes the risk of damage, offering a more reliable solution than conventional single-piece storage. Its compact and portable structure makes it convenient to transport for mobile tasks.

The socket's surface is coated with a durable phosphating layer, offering protection against oxidation and corrosion caused by external elements, thereby extending its lifespan.
