Screwdriver Bit Set Irwin Grot 1/4" Hex 25 mm, 3.0 mm tip, 10 pcs (MPN 10504346)

Irwin Grot screwdriver bit set with 1/4" hex shank, 25 mm length and 3.0 mm tip delivered as a pack of 10 pieces. These bits are designed for use with compatible bit holders, manual screwdrivers and power drivers that accept 1/4" hex shanks. The compact 25 mm length provides controlled reach for assembly, repair and maintenance tasks where a 3.0 mm tip size is required.

Advantages

The 1/4" hex shank ensures secure retention in standard bit holders and quick-change chucks, reducing slippage during use. A uniform 25 mm length delivers predictable engagement depth in confined spaces and on shallow recessed fasteners. The 3.0 mm tip is produced to fit mating fasteners accurately, supporting consistent torque transfer and minimizing cam-out. Supplied as a set of 10, the bits offer convenient replacement and distribution across tool kits or workstations.

• General assembly of small components

How to use

Insert the 1/4" hex shank into a compatible bit holder, quick-change chuck or screwdriver handle and ensure it seats fully before applying torque. Select the 3.0 mm tip to match the fastener head, engage the bit with the fastener and apply steady, controlled torque to avoid stripping. For power drivers, use appropriate speed and torque settings for the material and fastener size. Replace worn bits from the set to maintain accurate engagement and consistent results.

Usage recommendations

Store the bits in a dedicated holder or compartment to prevent loss and protect the tips. Inspect bits for wear or damage before use and replace any deformed tips to maintain safe and efficient operation. For repetitive work consider using torque-limited drivers or clutches to avoid over-torquing small fasteners.
