Hex Allen bit FELO 2.5 mm x 50 mm (FL03425510) — replaceable screwdriver bit

FELO hex (Allen) screwdriver bit with a 2.5 mm tip diameter and a 50 mm overall length, designed as a replaceable bit for manual or powered bit-holders. The bit provides accurate torque transfer to hex fasteners and an extended reach that is useful for working in recessed or narrow areas. Suitable for tasks requiring fine control and a small 2.5 mm hex interface, this replaceable bit is intended for electronics, precision assembly and maintenance work where a longer bit is advantageous.

Advantages

The 2.5 mm hex tip ensures precise engagement with small hex fasteners and reduces the risk of rounding. The 50 mm length increases accessibility to recessed screws and improves leverage in confined spaces. Manufactured to FELO standards, the bit offers consistent fitment in standard bit-holders and compatible powered drivers, enabling reliable torque transfer and repeatable performance during assembly and repair operations.

Suitable for

• Electronics assembly and repair
• Precision mechanical assembly
• Maintenance of small appliances and devices
• Accessing recessed hex fasteners in machinery or enclosures

Key specifications

• Tip type: hex (Allen)
• Tip diameter: 2.5 mm
• Overall length: 50 mm
• Mount: replaceable bit, compatible with standard 1/4" bit-holders and chucks
• Material/finish: hardened tool steel with wear-resistant surface treatment

How to use

Insert the bit into a compatible bit-holder or powered screwdriver chuck until it locks or seats securely. Align the 2.5 mm hex tip with the matching fastener and apply steady torque, keeping the driver axial to avoid cam-out. For delicate components, use moderate torque and controlled turns to prevent damage to fasteners or workpieces. After use, remove and store the replaceable bit in a protective case or rack to prevent tip damage and contamination.

Usage recommendations

For optimal results, match the 2.5 mm hex tip precisely to the fastener size, use appropriate torque settings on powered drivers, and inspect the bit for wear before precision tasks. Replace the bit when signs of rounding or excessive wear appear to maintain secure engagement and protect fastener heads.
