Greenlee 1/4 in SAE Hex Key

The Greenlee 0254-49 is a double-ended SAE hex key with a 1/4 in tip size. It is made from steel with a black oxide finish that resists corrosion. The tool is designed for fastening and loosening hex socket screws in maintenance and assembly tasks. It ships new and ready for immediate use.

Suits technicians needing a single 1/4 in key.

This key suits technicians who need a dedicated 1/4 in SAE driver for occasional use. The short arm length of 2 29/64 in and long arm of 5 9/64 in give two leverage options in one piece. Buyers needing metric sizes, insulated handles, tether points or a full set of keys should look at other products.

Tip size is 1/4 in SAE

The decisive specification is the 1/4 in SAE tip size, which determines whether the key fits the target fastener. Both arms share this same tip size, so the tool only works with 1/4 in hex sockets. Verify the fastener specification before purchasing to ensure compatibility.

Questions about this item

How do I fit the 1/4 in tip into a recessed fastener without rounding the corners?

Insert the short arm fully so the ball end seats squarely; the 2 29/64 in short arm gives leverage while keeping the tip aligned.

When will the black oxide finish need attention to stay corrosion resistant?

Wipe off moisture after each use and apply a light oil film; the oxide layer resists rust but wears off where the tip contacts the fastener.

At what point does the long arm start to flex under steady torque?

The 5 9/64 in long arm bends noticeably once force exceeds what the 1/4 in hex cross-section can transmit without permanent deflection.
