Punta TORX Wera TX 20, 4,5 mm, pezzo singolo

The Wera TORX bit TX 20, 4.5 mm, single piece is a precision-machined driver bit designed for reliable engagement with TORX fasteners. Manufactured by Wera, this single bit fits standard bit holders, magnetic bit holders and quick-change chucks. Its 4.5 mm nominal head diameter and TX 20 geometry ensure controlled torque transfer and reduced cam-out during repair, assembly and maintenance operations.

Advantages

This single-piece TORX bit provides accurate fit and repeatable performance with TORX recessed screws. The hardened tip and precise machining support longevity and wear resistance under typical workshop and field conditions. The compact format makes it easy to carry as a spare in a toolbox or integrate into bit sets, while compatibility with common holders and chucks enhances versatility across different powered and manual drivers.

Suitable for

• Electronics and appliance repair where TX 20 fasteners are used
• General assembly and disassembly of furniture or equipment with TORX screws
• Maintenance tasks in automotive and bicycle servicing that require TX 20 bits
• Workshops and on-site service kits as a replacement or spare bit

Key specifications

• Drive type: TORX (TX 20)
• Nominal head diameter: 4.5 mm
• Quantity: single piece
• Compatibility: standard 1/4" hex bit holders, magnetic holders, quick-change chucks
• Material properties: hardened tool steel tip with precision-machined geometry

How to use

Insert the Wera TX 20 bit into a compatible bit holder or chuck until it is securely seated. Align the bit with the TORX fastener and apply steady axial pressure while turning the driver to engage the fastener. Use appropriate torque settings on powered drivers to avoid over-torquing, and remove the bit by pulling it from the holder or opening the quick-change mechanism. Store the single bit in a bit organizer or toolbox to protect the tip from damage.

Recommendations

Use the bit only with correctly sized TX 20 fasteners to prevent rounding of the screw or wear to the bit tip. For high-torque applications, use a matched torque-limited driver or manual driver to minimize stress on the bit and fastener. Replace the bit if signs of tip deformation or excessive wear appear.
