Greenlee 0254-12 – Frequently Asked Questions

1) What hex sizes come in the Greenlee 0254-12 folding hex-key set?
Nine inch sizes fold into the one case: 5/64, 3/32, 7/64, 1/8, 9/64, 5/32, 3/16, 7/32 and 1/4 inch. That is the whole set, all SAE/inch, no metric keys included. If your fasteners are metric, this is not the set to order.
2) Will the Greenlee 0254-12 reach set screws on a connector inside a panel where I can't get the key straight on?
That is what the ball ends are for. The 0254-12 drives at an angle up to 30 degrees off the fastener axis, so you can work a set-screw lug or connector in an enclosure without lining the key up square. Keep in mind ball ends carry less torque at angle than a square-cut end, so break a tight screw loose with the key straight and finish it on the angle.
3) Is a folding hex key set better than loose L-keys for a service truck?
For field service and mobile kits, folding wins because nothing goes missing. All nine keys pivot out of a single one-piece handle/case, and each size is laser-etched on the case so you are not eyeballing the small ones. Loose L-keys still have the edge when you need to reach deep into a recess or put a wrench on the short leg for extra torque, since the folding body limits how far a key can go into a bore.
4) Does the Greenlee 0254-12 meet a dimensional standard for hex key tolerance?
It is built to ASME/ANSI specification, which is the dimensional standard that governs hex key across-flats sizing. That matters on small sizes like 5/64 and 3/32, where an out-of-tolerance key rounds a socket head fast.
5) Is this hex key set sized for electrical work specifically?
The size spread suits electrical trade work: 5/64 through 1/4 inch covers the set screws found on panel and enclosure assembly, mechanical lugs and set-screw fittings, and general MRO. For large feeder lug screws above 1/4 inch hex you will need a separate larger key or a hex bit socket.
6) Will the Greenlee 0254-12 hold up in a damp or outdoor jobsite box?
The handle/case is powder-coated for corrosion resistance, and the keys themselves are heat-treated and tempered. It is a tool-steel set with a coated body, so normal jobsite damp and handling are fine; standing water or long outdoor storage will still rust exposed key surfaces like any hex key.
7) What is the exact part number to order the Greenlee 9-piece folding ball-end hex key set?
Greenlee 0254-12. It ships as one complete 9-piece set, so there is nothing further to specify, no size or finish choice.
