Q: What does the radius-corner design improve?
A: By contacting the sides of fasteners instead of corners, it minimizes rounding and prolongs both tool and fastener life.

Q: What is special about the T25 internal star profile?
A: The internal star (Torx) design fits precisely into T25 fastener heads, maximizing torque transfer and reducing slipping.

Q: Is this socket impact-rated?
A: Yes, it’s forged from chrome-molybdenum steel and engineered to meet or exceed ANSI and ASME impact socket standards for reliability under load.
