Klein Tools 70540T – Frequently Asked Questions

1) Which Torx sizes are in the Klein Tools 70540T folding key set?
Eight Torx blades: T9, T10, T15, T20, T25, T27, T30 and T40. That covers the sizes you hit most often on electrical panel screws, appliance and HVAC covers, and machinery fasteners. There are no hex (Allen) or metric blades in it, so if you need standard hex sizes you want a separate hex folding set.
2) Will the 70540T Torx key set actually fit in a tool pouch pocket?
Yes. Folded it measures 4.56 inches long, 1.07 inches wide and 1.57 inches at its tallest point, and it weighs 0.49 lbs, so it drops into a pouch pocket or a shirt pocket without snagging. The blades are 2 to 2.5 inches long when opened.
3) Can I use one blade at a time on the Klein 70540T, or do they all swing out together?
Each blade opens independently through 270 degrees, so you pull out only the size you need and the rest stay in the handle. Side entry access means you can get at a blade without unfolding the whole set, which matters when you are working in a panel with one hand.
4) Are the tips on this Klein folding set square-cut or ball-end?
Square-cut, flat ends. They seat full depth in the fastener for maximum contact, which is what you want on tight or over-torqued Torx screws where a rounded tip would cam out. The tradeoff is you cannot work at an angle the way a ball-end lets you, so for off-axis access you need a different style of key.
5) Will a folding Torx set hold up in a damp or outdoor service truck?
The blades are heat-treated CR-V steel with a black phosphate finish for corrosion resistance, and the handle is reinforced nylon rather than bare metal, so it tolerates truck and field conditions. Black phosphate is a coating, not stainless, so wipe it down after wet work if you want it to stay clean.
6) Is the Klein 70540T one tool or a loose set of keys I have to keep track of?
One tool. All eight Torx blades are captive in a single 4.6 inch reinforced nylon handle, counted as one piece, so nothing goes loose in the bottom of a bag or gets left in a panel. That is the main reason crews spec folding sets over loose L-keys for fleet and MRO kits.
7) What is the Klein part number and color for ordering the 8-piece folding Torx set?
Order Klein Tools model 70540T. The handle is orange, which makes it easy to spot in a pouch or on a bench and easy to tell apart from Klein's hex-size folding handle when both are in the same kit. Country of origin is Vietnam.
