Screwdriver bit socket FELO FL03907010, SW 7, 66 mm

Socket screwdriver bit FELO FL03907010, SW 7, 66 mm is a replaceable bit designed for use with bit holders, ratchets and power tools that accept standard bit sockets. It fits hex-head fasteners with a 7 mm across-flats dimension (SW 7) and has a 66 mm overall length to reach recessed bolts or nuts. The bit is intended for workshop, assembly and maintenance tasks where reliable engagement and accurate torque transfer are required.

Advantages

The FELO socket bit offers a precise hex profile for stable contact with fasteners and reduced cam-out. Its 66 mm length provides additional reach compared to short bits while remaining compact for ease of handling. Manufactured to durable standards, the bit resists wear under repetitive use and maintains a consistent fit with compatible bit holders and sockets. The design allows quick replacement and compatibility with manual and powered drive tools that accept standard 1/4" hex bit sockets.

Suitable for

• Tightening and loosening SW 7 hex-head bolts and nuts
• Assembly lines and production fixtures requiring consistent torque
• Workshop repairs and maintenance where recessed fasteners are present
• Use with bit holders, ratchets and compatible power drivers

Key specifications

• Profile: Hexagon across flats (SW 7)
• Length: 66 mm overall
• Compatibility: Standard 1/4" hex bit socket systems and holders
• Material and finish: Hardened tool steel with wear-resistant surface (manufacturer standard)
• Application: Designed for manual and powered tightening/loosening of hex fasteners

How to use

Select a compatible bit holder, ratchet or power driver that accepts standard 1/4" hex bit sockets. Insert the FELO socket bit securely into the holder and engage it with the SW 7 fastener head, ensuring full seating before applying torque. For power tools, set appropriate speed and torque settings to match the fastener and avoid over-tightening. After use, inspect the bit for wear or deformation and replace if the hex profile shows signs of rounding to preserve safe and accurate operation.

Usage recommendations

Use with tools that match the bit's drive system and select torque settings appropriate to the fastener and material. Store the bit in a dry tool kit or socket rail to prevent corrosion and keep the hex profile free of debris to ensure consistent engagement.
