pop rivets - proper way to use?

[pete75]

Monel metal blind rivet are available.
They are used in marine applications such as aluminium masts.

Monel, any of a group of nickel-copper alloys, first developed in 1905, containing about 66 percent nickel and 31.5 percent copper, with small amounts of iron, manganese, carbon, and silicon. Stronger than pure nickel, Monel alloys are resistant to corrosion by many agents, including rapidly flowing seawater.

Yep I use them for mast fittings - just hope they never have to resist rapidly flowing seawater...

Turns out I have a modest collection of cross pein hammers... who knew?? Anyway, the rivets are suitably hammered and I'm off to find the wettest puddles possible in order to test the 'guards. The clearance under the front brake is mighty tight - I'm wondering if I might be better off wrapping the brake up in cling film instead !

Rather than rivets of any type, I've gone for a version of Mick F's system, although at my own - ham-fisted - level. I cannot now remember the difference between bolts and screws. Anyway, I've used screws/bolts with thin, flat heads, fitted from the inside of the guard. The nuts then go on the outside, being shortened if necessary. This allows a bit more flexibility at the fitting stage and subsequently less vulnerability to road salt etc.

Re your front guard, improvisation may be the key. One possibility is to cut the front guard so part stops behind the fork crown and the other pit is fastened in front of it. Once upon a time "spearpoint" extensions were sold for this purpose. There's a thread somewhere on here illustrating how somebody used a modified rear guard at the front to get maximum protection.

Neither can anyone else... there isn't an absolute distinction:

Cross peins are relatively hard to find, especially nice ones with an ash shaft. I've been looking for something between a pin hammer and 12oz. for a while now....

Difference is in the application. You screw into a component, you bolt something together with a nut. Often interchangeable, though not always.

That's often the case, but there are exceptions to every attempted absolute distinction...

I'm not reading through pages of links - You can't bolt something together unless the fixing protrudes from the other side to put a nut on it. You can't screw into something unless it's threaded (Or the screw creates a thread) There are no exceptions to that.

Cylinder head bolts on piston engines. They typically end inside the block and don't have nuts attached.

Go on then, screw one into a cylinder head

For every attempted definition of the distinction between screws and bolts there's an exception in how the words are used for real objects in the real world.

That includes attempted definitions based on whether they end up inside a material or protrude and have a nut on the end, and on whether they're threaded all of the way or not. The former, as used above, is a much more useful engineering distinction than the latter, but there are still exceptions.

No, the application is straightforward and well understood. Bolting something together is a clamping force, screwing something together relies on the thread gripping. There really are no exceptions to that. The fixing used can often be interchangeable, if you wiki hard enough I'm sure you'll find fixings miss-named and mis-described, or where something other than a nut is used to bolt into, or bolts with full threads, but the two applications are distinct and easily definable.

A bolt has a plain or unthreaded section next to the head, only part of the shaft is threaded. A machine screw is threaded along the whole length of its shaft.

That's my understanding as well

It's often quoted.

What do you each call this fastener?
