SATA SC59257 5-Piece 1/4" Drive 25l Bit Hex 7 x 25mm

The set includes five hex bits, all in 7 mm hex size with a 25 mm length, designed for use with 1/4" drive tools. The bits are heat-treated S2 steel insert bits built for high torque and long life.

7 mm hex bits are intended for larger hex fasteners, where a strong grip is needed to minimize stripping and slippage under high torque. If your fasteners require a larger hex size, these bits help ensure a secure fit and reliable drive.

Yes. These bits are sized for standard 1/4" drive tools, so they should work with most ratchets, adapters, and bit holders that accept 1/4" drive bits.

They’re well-suited for automotive maintenance, machinery assembly/disassembly, bike repairs, and any application involving larger hex fasteners where a robust bit is beneficial.

1) Ensure the bit and drive are clean and free from debris. 2) Align the bit squarely with the fastener head. 3) Apply steady, perpendicular force with a suitable torque—avoid sudden or excessive torque. 4) If using adapters or extensions, use them sparingly to prevent wobble or misalignment.

Wear eye protection and gloves if needed, avoid using worn or damaged bits, ensure proper seating to prevent cam-out, and don’t exceed recommended torque on fasteners to avoid bit or fastener failure.

They feature heat-treated S2 steel insert bits for increased strength and longevity. After use, wipe away debris, keep them dry, and store in the included display pack or a protective case to prevent corrosion and damage.

These are standard 1/4" drive bits, so they should be compatible with most brands and tools that use a 1/4" square drive. Always confirm that your tool’s drive size matches before use.
