A introduction to KTC universal joint (KTC BJH20)

[roggy]

There are roughly three types of universal joints: the three-piece type, the pin type, and the pinless type. The three-piece type is the most traditional, but it’s not very smooth, sometimes hard to use. The pin type is smoother than the three-piece design, but all the force is applied to the pin, leading uneven load distribution.
Most pinless designs use a hexagonal drive, allowing the force to be distributed more evenly. However, there’s also a very unique example in this category—the KTC BJH20. It features a dodecagon drive. I recently got one and even took it apart to admire its internal structure.

Very nice write up and review of the internals.

I’ve said this before but…KTC is criminally underrated on this forum.

I own many KTC tools and they are ALL top shelf.

I don't have a lot of experience with "pinless" impact universals. Based on not much information, (I own three "pinless" impact swivel sockets but don't use 'em often) I find that they have much more internal friction, leading to a torque reduction through them (more than pin-type which have very low friction.)

I'm prepared to learn something, but I'll stick with pin type impact swivels for now.

Their extra long ratcheting wrenches are the nicest that I have ever held, but I don’t own any.

The only KTC tools that I have are the cherry blossom wrenches.

Impact power tools often apply pin type, I forget to mention that all of the universal joint adapters introduced are hand tools, and thanks for the reply.
