Application and User

The Wiha Tools 33485 is a 1/4" SAE hex key designed for tightening and loosening hex fasteners. Its 5 57/64 in length provides extended reach and leverage for maintenance and assembly tasks. The CRM-72 steel blade with black oxide finish resists wear and corrosion. A plastic handle improves grip and comfort during use.

Who Should Choose Another Tool

This single fixed-size key does not suit technicians who need multiple tip sizes in one set. Buyers requiring a ball-end for angled access or a folding holder for portability should look at other configurations. It is not a ratcheting or powered driver, so high-volume or repetitive fastening will be slower.

Deciding Specification

The 1/4" tip size is the critical dimension that determines whether this key fits your fasteners. Verify the hex socket on your bolts or nuts matches this exact SAE size before purchase. The 5 57/64 in overall length then decides if the reach and leverage meet the workspace constraints.

Questions about this item

Should I pick the 5 57/64 in or the 7 in version for tighter access?

The listed overall length is 5 57/64 in, which is the measurement to use when checking clearance in your workspace.

What does the 1/4" tip size mean when I am turning a fastener?

It fits a 1/4" hex socket or bolt head, giving full contact across the flats for maximum torque without rounding.

How does the black oxide finish affect the tool in daily use?

The black oxide coating resists corrosion and reduces glare, while the CRM-72 steel blade provides the strength needed for high-torque applications.
