KFFKFF 12 Pc Shallow Impact Socket Set, 3/8" Drive, SAE 5/16"-1", 6-Point, Cr-Mo Steel, for Vehicle Maintenance, Clear Markings, Durable, with Case

Crafted from high-quality alloy steel, the impact socket set undergoes a series of heat treatment processes, including high-temperature quenching and low-temperature forging. This meticulous process results in a remarkable hardness level of HRC42-48.

Designed for professional use, this set is compatible with a wide range of tools such as electric wrenches, impact wrenches, ratchet wrenches, rod benders, and more. It is perfect for automotive maintenance, equipment assembly, industrial manufacturing, power inspections, and various other applications.

Featuring a hexagonal socket design, the impact socket set creates a gap between the nut and the edges during operation. This innovative design effectively minimizes friction and wear, allowing it to withstand high impact forces and effortlessly remove bolts.

The impact socket set boasts extra-large size markings that are laser-etched and rolled onto the sockets. These markings remain clear and easily identifiable even under challenging lighting conditions. Furthermore, they are highly resistant to wear, ensuring long-lasting visibility.

Unlike traditional one-piece storage solutions, the impact socket set comes with a split-strengthened carrying case. This heavy-duty case offers exceptional durability and is less prone to breakage. Its portable design allows for easy transportation, making it ideal for work on the go.

To enhance longevity, the surface of each socket in the impact socket set is treated with a dense phosphating film. This protective coating effectively prevents oxidation, corrosion, and other external factors from damaging the surface of the sleeve, ensuring a prolonged service life.
