## Long description

FELO hex (imbus) screwdriver bit 4.0 mm with a 50 mm length is a replaceable bit designed for use in bit holders, ratchet screwdrivers and power drivers that accept standard bits. Made from hardened steel and finished for corrosion resistance, the bit provides a precise fit into 4.0 mm hex sockets and transfers torque reliably for assembly, maintenance and repair tasks.
Advantages
The 50 mm length gives improved access to recessed or hard-to-reach fasteners while retaining control and accuracy. Hardened steel construction and precise machining reduce cam-out and wear, ensuring consistent engagement with hex fasteners.

Key specifications

How to use
Insert the bit securely into a compatible bit holder or screwdriver chuck until it locks. Align the hex tip with the fastener and apply steady axial pressure while turning the driver. For power tools, use controlled torque settings to avoid over-tightening. Inspect the bit tip before use and replace it if rounded or damaged to maintain a precise fit.
Usage recommendations
Store the bit in a holder or toolbox to protect the tip, avoid using it as a pry tool, and match torque settings on powered drivers to the fastener specifications to prolong bit life and prevent fastener damage.
