Stihl Driver Bit T27 X 125mm - OEM Number: 0812 542 2104

The Stihl Driver Bit T27 x 125mm (OEM 0812 542 2104) is a genuine replacement Torx driver bit designed for servicing and maintaining a wide range of Stihl handheld power equipment. Featuring a T27 Torx tip and an extended 125mm shaft, it provides easy access to recessed fasteners commonly found on chainsaws, brushcutters, hedge trimmers, blowers, cut-off saws, and other Stihl machines. The long reach allows technicians and users to work efficiently in confined areas without compromising control or accuracy.

Manufactured to OEM specifications from hardened steel, the driver bit is engineered to provide precise engagement with Torx fasteners, reducing the risk of cam-out and fastener damage. The standard 1/4-inch drive makes it compatible with a wide range of bit holders, ratchets, screwdrivers, and power tools, making it an essential addition to any workshop or service kit.

IMPORTANT INFORMATION

Always confirm that a T27 Torx driver is the correct size for the fasteners being serviced before use. Using the correct driver size helps prevent damage to the fastener head, improves torque transfer, and reduces the likelihood of slipping during installation or removal.

To maximise service life, inspect the driver bit regularly for signs of wear, rounding, or damage, particularly after repeated use on seized or heavily tightened fasteners. Replacing worn driver bits helps maintain accurate engagement with Torx screws and reduces the risk of damaging both the tool and the machine components during servicing.
