US PRO Industrial 3435 10pc 1/2" Drive Impact Spline Bit Socket Set (M4–M18, Tamper)

The US PRO Industrial 3435 10pc 1/2" Drive Impact Spline Bit Socket Set is built for demanding applications where strength, security, and reliability are essential. Designed around European-style spline fasteners, this set is ideal for automotive, commercial vehicle, and industrial environments where tamper-resistant fixings are commonly used.

Each socket body is manufactured from chrome vanadium (CR-V) steel, providing the structural strength required to handle high torque loads, while the S2 steel spline bits deliver excellent hardness and resistance to twisting under impact use. This combination ensures dependable performance with impact wrenches, breaker bars, and high-torque ratchets, even in challenging conditions.

The set includes a carefully selected range of spline sizes from M4 to M18, incorporating tamper-resistant variants for added security applications. A durable phosphate finish enhances corrosion resistance and helps protect the tools from wear in busy workshop environments. Supplied in a robust metal case, the sockets remain organised, protected, and easy to transport—perfect for both fixed workshops and mobile technicians.

Engineered for professional use, the US PRO Industrial 3435 delivers the durability and versatility required for modern fastening tasks involving spline and security fasteners.
