Impact screwdriver bit T20 90mm S2 by Tvardy — pack configuration 1/10/50/400

Tvardy impact screwdriver bit T20, 90 mm in length, made from S2 steel, is designed for use with impact drivers and screwguns to install and remove T20 fasteners. The 90 mm working length provides reach and control in medium-depth applications, while the S2 material improves toughness and resistance to repeated shock loads typical for impact tools. The product is supplied in a pack configuration intended for retail and bulk distribution.

Advantages

The S2 steel construction offers higher hardness and better resistance to deformation under impact compared with standard tool steels, extending bit life in frequent-use scenarios. The T20 profile is machined to precise tolerances to reduce cam-out and ensure consistent engagement with T20 fasteners. The 90 mm length balances access and stability for use in recessed or partially obstructed screw locations. Packaging options support both single-unit retail and larger-volume professional purchases.

Suitable for

• Assembly and disassembly of furniture and fixtures using T20 fasteners
• Construction and carpentry tasks requiring impact driving of medium-length screws
• Electrical and HVAC installations where access depth requires a 90 mm bit
• Maintenance and repair work with frequent impact-driver use

Key specifications

• Tip type: Torx T20
• Length: 90 mm
• Material: S2 tool steel
• Intended use: Impact drivers and screwguns
• Finish: machined working tip (factory standard finish)

How to use

Insert the T20 impact bit securely into the driver chuck or quick-change holder before starting the tool. Align the bit with the fastener head and apply steady axial pressure while operating the impact driver at a controlled speed. For removal, reverse the rotation and maintain firm contact to avoid slipping. Inspect the bit tip regularly for wear or rounding; replace the bit when the engagement becomes unreliable to prevent damage to fasteners.

Usage recommendations

Use the bit exclusively with impact-rated drivers or screwguns and avoid using in hand-only screwdrivers to preserve the tip geometry. Store bits in their original packaging or a dedicated holder to prevent tip damage. When working with high-torque applications, consider using appropriately sized impact bits and ensure the driver settings match the fastener and material.
