Laser Tools 7707 Hex Key 1/2"D 9mm For Brake Calipers

The Laser Tools 7707 is a specialized 9mm hex (Allen) bit socket, precision-engineered for the removal of brake caliper guide pins. While 7mm and 8mm hex pins are common, many modern European vehicles—including certain BMW, Mercedes-Benz, and VAG models—utilize a specific 9mm fastener that is rarely found in standard tool sets. Attempting to use a 10mm bit or a rounded 8mm tool will lead to the immediate stripping of the pin head. This socket features a 1/2" square drive, allowing for the use of long-reach breaker bars to overcome the high-temperature "stiction" and thread-lock often found on brake components. The bit is made from S2 steel for maximum torque resistance, while the socket base is Chrome Vanadium, ensuring a professional-grade tool that won't twist or shatter under load.

• Specialist 9mm Size: Essential for specific BMW and VAG brake caliper guide pins.
• 1/2" Square Drive: Allows for significant leverage to crack open seized fasteners.
• S2 Steel Bit: High-tensile material designed to prevent rounding and bit failure.
• Automotive Essential: A "problem-solver" tool for technicians servicing modern European fleets.
