This L-shaped extension bar wrench is forged from 50BV30 alloy steel, offering high tensile strength, high hardness, excellent toughness, superior wear resistance and deformation resistance. Heat treatment can increase hardness and strength, thereby improving durability and wear resistance, and enabling high-torque applications; electroplating surface treatment can provide corrosion resistance and a smooth surface to reduce friction.The socket drive head can be locked onto a ratchet wrench and extension bar for greater leverage and torque. The spring-loaded detent ball securely holds the socket in place, preventing it from falling. The non-slip knurled handle allows for easy finger rotation, ensuring comfortable and convenient operation even with oily fingers.
