Screwdriver bit Wiha 27816 — Torx T15, hexagonal shank, 175 mm

Single Wiha 27816 screwdriver bit with a Torx T15 tip, hexagonal shank and 175 mm length designed for driving Torx fasteners in assembly, maintenance and repair work. The bit is lightweight and intended for use with compatible bit holders, bit extension bars and screwdrivers that accept a hexagonal shank. Its elongated profile helps reach recessed screws and provides additional reach in tight spaces.

Advantages

The Torx T15 tip provides accurate engagement with compatible fastener heads, reducing cam-out and wear. The hexagonal shank ensures secure chucking in standard bit holders and quick-change systems. At 175 mm length the bit offers extended reach compared with standard bits while remaining lightweight for convenient handling and reduced fatigue during repetitive tasks.

Suitable for

• Driving and removing Torx T15 screws in electronics assembly and repair
• Accessing recessed fasteners in machinery and equipment
• Maintenance tasks where an extended bit is required to reach screws
• Use with magnetic or mechanical bit holders and quick-change chucks

Key specifications

• Tip type: Torx T15
• Shank type: hexagonal shank for secure holder engagement
• Overall length: 175 mm
• Weight: approximately 17.83 g
• Material and surface treatment: hardened steel construction for wear resistance (manufacturer typical specification)

How to use

Insert the hexagonal shank into a compatible bit holder, quick-change chuck or screwdriver that accepts hex shanks until it seats firmly. Align the Torx T15 tip with the fastener head and apply steady axial pressure while turning the driver to avoid slipping. For deep or recessed screws, use the full length of the bit to reach the fastener while maintaining control at the holder end.

Usage recommendations

Use with appropriately sized Torx T15 fasteners only. Avoid excessive torque beyond the bit and fastener rating to prevent tip rounding. Keep the bit clean and inspect the tip before each use; replace the bit if wear or damage is visible to maintain secure engagement and reduce the risk of fastener damage.
