Those are the Perfect socks to use with tire boots !!

They should be real cozy together.

Through this forum I discovered that JIS screws are really Phillips. If I don't know in advance which #2 crosshead screwdriver will best fit a screw, maybe Phillips screws and drivers are easy to damage, and a little damage can make a big difference. Maybe I should stick with easy-to-replace bits.

I love my set of ISO ball-end hex keys. Then I saw this set. The removable caddy holds 8 Security Torx and 2 Phillips bits as clearly labeled as the hex keys, along with a magnetic adapter that fits the H8 key. It made changing brake fluid more convenient. To keep it on my bike, I'd remove the H10 key. If I still encounter Pozidriv screws, I can replace a couple of Torx bits with PZ.

From the outset, toolmakers favored hex keys for applying torque. Assembly lines adopted Phillips to keep power tools from snapping screws. The downside was that drivers needed frequent replacement. Torx was patented in 1967, when assembly-line drivers had reliable clutches. The selling point was long tool life. On an assembly line, a Torx driver would also outlast a hex driver. With a hex key, each pound of torque generates 1.75 pounds of radial force, trying to crush the driver and burst the socket. On an assembly line, that's wear and tear for the tool. Torx drivers generate very little radial force.

Security was also a reason Torx screws were used: consumers didn't have the drivers. When consumers bought Torx drivers, the Security Torx screw was invented.

You'll need a T-15 bit for your Tektro brakes, and an S2 T-20 bit for your Bafang motor, and to install a speed magnet on your spoke (a @spokewrench won't work ).

Installation And Servicing of Bafang products is for Professionals only !!

I remember breaking that damn pin off a Torx screw before I could buy a Torx security bit.

I also needed a T-30 for a bolt that, it turned out, held the caliper together. I was trying to follow the generic instructions that came with the kit. These bits will allow me to ruin more equipment than ever before.

That's not a T-30 (but it does kinda fit in a sloppy way)
It's an H-5mm

Well, chances are pretty good that your T-30 will ruin your Hex bolts.

If your 5mm Hex key no longer fits your caliper bolts, then the damage is already done.

This was 1 of 2 T-30 screws that hold the halves of the caliper together. Tektro really didn't want me to remove it. I showed them!

Huh, I dunno

My two halves are pinned or riveted together,..

Looks like I'll have to drill them out if I wanna open up my calipers?

It's probably your fault ya know.
They heard about what you did and put up a Firewall.

you like destroying brake calipers??? whats the point of taking them apart?

If they end up destroyed or needing to be replaced, (for whatever reason) I'm gunna take em apart.
I like knowing how things work.

Here's a 1/4 drive torque driver set I bought

But for accuracy I sometimes rely on this older 1/4 drive

I have these on a couple of bikes, the D-fuse seatpost

The workshop
Nothing too serious gets done here. No serious mods or wheel truing like.

I shopped at Amazon for a set of Phillips bits, and some advertised altered shapes to avoid camout (the reason factories adopted Phillips). So screwdriver manufactures are taking liberties with the Phillips name, and maybe screw manufacturers are, too. Where camout would be bad, why not use Pozidriv? (In the 1970s, I often encountered Reed & Prince crosshead screws, a crosshead that with the right driver, didn't cam out.)

Better yet, if a designer doesn't want camout, why not use Allen or Torx? I'm impressed that like 12-point sockets, Torx don't require a tight fit. Yesterday I broke loose a screw on my brake rotor before realizing the bit was too small. No damage. The correct bit also fit loosely.

The other day I put up an outdoor railing. Each of 4 brackets was to be secured with 4 20mm M5 screws with #2 crossheads. My Klein, which usually works, didn't. Neither did a PZ2 or a PH2 bit. My old Craftsman worked beautifully.

With coarse, thin threads, these screws looked like what you'd use for tin roofing. I suppose most people use power tools for kits like this, and those threads wouldn't stand much torque. I guess the screw manufacturer used a Phillips variation designed to cam out easily, and it took the right variation of a Phillips driver to put even a little torque on it.

My latest new tools, cone wrench (my old one is presumably now very happy with an unknow co-worker...) and a nut wrench for tight spots, also very thin spanner for balljoints and a checking tool for torque on bolts.

Yesterday I repaired a bike with a chopstick. The connection pins to the rear hub motor were bent. Another bike, a Velotric was attacked by a cat who bit through the display wires and shorted it. I spliced it and did a system reset. It took all of ten minutes. Who ever heard of a cat attacking a bike? A cat biting live wires will soon get a visit by Karma holding hands with Darwin.
