5-Piece Metric T-Shape Hex Key Set

This Wiha Tools set provides five metric hex keys in a T-handle configuration for comfortable, high-torque turning. The kit covers 4 mm, 5 mm, 6 mm, 8 mm and 10 mm tip sizes, addressing common fastener requirements across automotive, mechanical and maintenance tasks. A plastic holder keeps the keys organised and portable. The black oxide finish protects the steel shafts from corrosion during storage and use.

Sustained torque comfort and durability

The T-shape handles distribute force across the palm, reducing fatigue when driving or breaking loose stubborn fasteners over long periods. Steel construction with HAWA material specification resists rounding and deformation under continuous load. Long shaft lengths between 5 15/16 in and 6 15/16 in provide reach into recessed areas without sacrificing leverage. Buyers needing smaller precision keys or imperial sizes will require a different set.

Questions about this item

Does the black oxide finish hold up to daily workshop heat without flaking?

The black oxide coating on the HAWA steel resists corrosion and wear during extended use in warm environments.

Do I need a separate holder or case to keep these five metric T-shape keys organised?

A plastic holder is included with the 33478 set, so the 4 mm, 5 mm, 6 mm, 8 mm and 10 mm keys stay together without extra storage.
