Excellent Reach and Build Quality

I used Mastercraft's Extra long ball-end and Hex-L key set for tightening and adjusting the bolts on my kid’s bike. Some screws were tucked deep inside the frame where my regular hex keys couldn’t reach. These extra-long Mastercraft keys made it simple—the length gave me the leverage I needed, and the ball-end let me work at an angle without slipping.
They felt strong, precise, and cleaner to use than the basic set I already owned.
Minor downside: the holder is a bit tight.
Overall, excellent performance for a small but tricky project.

These can always come in handy

I used this tool to work on my project cars, it really comes in handy with helping reach in tight spots and everyone should have a set of these in their toolbox!

MASTERCRAFT Extra Long Ball-End Hex-L Key Set

Today we received our free product from Butterly which was the Mastercraft Extra-Long Ball End Hex-L Key Set. We used it to fix our ATV where there are a lot of tough to reach places. This set of keys worked amazing for that as they are extra long and easy to hold in order to reach those tough places. They seem like a very durable set as well! Run, don’t walk as these would make an awesome gift for that mechanic, plumber or electrician in your life!! Can’t wait to see what other project we will use these on next. Thank you Butterly and Canadian Tire!!

Very useful

The kit is very useful, I used it to mount my bed. The quality is exceptional.
It has 9 pieces with different sizes, could be used for a lot of different things
Can’t recommend enough.

I've been using the End Hex Key Set for a few days now, and it has quickly become a go-to tool in my toolbox. The keys are well-made, with a solid feel and good grip, making it easy to apply torque without slipping. The variety of sizes covers most of my needs, whether for furniture assembly or bike repairs. I appreciate the durability and how compact the set is, which makes storage simple. Overall, it's a reliable, high-quality set that offers great value for its versatility and performance. Highly recommended and a perfect christmas gift or birthday gift :)

The extra long are even better

So we actually have the Mastercraft long ball set and we have had for years I recently took a couch apart and really wish I had the extra long set because I needed to put my key in my drill to get extra length for leverage ! We just bought a new bed frame and these were perfect being extra long to get those small spaces!

A+ for this set as well
