Impact screwdriver bit set Tvardy T40 50mm S2 (pack counts: 1/10/50/500)

Tvardy impact screwdriver bit T40, 50 mm length, made from S2 tool steel, is designed for use with impact drivers and screwguns. The T40 Torx profile delivers secure engagement with fasteners, while the 50 mm length provides reach in recessed or offset applications. Manufactured for repeated impact use, the bit withstands shock loads and reduces the risk of rounding the fastener head when driving or extracting screws.

Advantages

The S2 tool steel construction offers a balance of toughness and hardness suitable for impact applications, improving resistance to wear and deformation. Precision-machined Torx geometry ensures consistent fit and reduced cam-out under high torque. Available in multiple pack counts (1, 10, 50, 500), the product accommodates single replacement needs and bulk procurement for trade use, keeping a steady supply on site.

Suitable for

• Driving and removing Torx T40 fasteners with impact drivers or screwguns
• Construction and assembly tasks requiring repeatable high-torque fastening
• Vehicle and machinery maintenance where durable bit life is needed
• Workshops and production lines that benefit from bulk packaging options

Key specifications

• Drive type: Torx T40
• Length: 50 mm
• Material: S2 tool steel
• Designed for: impact driver and screwgun use
• Finish: machined tip geometry for accurate engagement

How to use

Insert the T40 bit securely into the impact driver or screwgun chuck until it seats firmly. Select the appropriate torque and speed settings on your tool for the screw size and material. Align the bit with the Torx fastener, apply steady axial pressure, and operate the tool while maintaining alignment. For removal, reverse the tool direction and use controlled speed to avoid cam-out or damage to the fastener head.

Usage recommendations

Use protective eyewear and follow the impact driver manufacturer’s safety instructions. Replace bits showing significant wear, deformation, or burrs to maintain driving accuracy and reduce the risk of fastener damage. For prolonged life, avoid using impact bits on non-impact tools and store bulk packs in a dry environment to prevent corrosion.
