SKT 3/8 CROWFT BK 1 1/16 - Martin Tools

The Martin Tools BLKBC34 3/8" Drive 1-1/16" Crowfoot Wrench is a professional-grade solution engineered for accessing fasteners in extremely confined and hard-to-reach automotive and industrial environments. Featuring a specialized 12-point flare nut opening, this tool allows technicians to engage tubing nuts and other fittings that are inaccessible with standard wrenches or sockets, making it indispensable for critical applications requiring precise torque and secure grip.

Key Features

• Enhanced Access: Designed with a slim profile for superior reach to fasteners in tight spaces, such as hydraulic lines, fuel lines, and sensor connections.
• 12-Point Flare Nut Design: Offers increased flexibility and maximum surface contact area, effectively minimizing the risk of rounding on critical or softer fittings.
• 3/8" Drive Compatibility: Integrates seamlessly with standard 3/8-inch drive ratchets, extensions, and torque wrenches, providing versatile application and the ability to meet OEM torque specifications.
• Professional Durability: Manufactured from drop-forged alloy steel and finished with an industrial black coating, ensuring exceptional strength, longevity, and resistance to corrosion in demanding shop environments.
• Precision Fit: Precision machined for a secure and accurate fit on fasteners, enabling maximum torque transfer without slippage.

Applications

This crowfoot wrench is an essential tool for automotive mechanics, heavy equipment technicians, and industrial maintenance professionals. It is particularly valuable for tasks that involve:
