Phillips bit PH4, 1/4 inch drive, steel alloy, pack of 10 - Bahco 59S/PH4

PH4 turns up rarely, and when it does the joint carries noticeable torque. That is where the shape stability of the tip decides whether the screw comes loose or the recess breaks out, which is why this bit is made from a high-performance steel alloy.

Features

• Size PH4, the largest common cross recess size for high-torque joints
• 1/4 inch hex drive to DIN 3126-C 6.3 and ISO 1173
• High-performance steel alloy, zinc-phosphated
• Compact body without an extension, torque is transferred right at the holder
• 10 bits per plastic box, worthwhile where PH4 is needed regularly
