Quoted message said:In my tool closet I have a few containers of assorted screws and bolts.
I also have a missing allen-head screw from my rear bike rack.
Is there anywhere I can buy a box of miscellaneous bike bolts? You know, an assortment of common
or somewhat-common sizes and lengths, all with the allen head?
By the way, what do you call screws/bolts with allen-wrench heads. A hex bolt is for a
wrench/ratchet, so what's it called if it needs an allen wrench?
You might ask at your LBS. We end up with more small fasteners than we'll ever use in some sizes
such as the 5mm screw that holds your carrier to the frame end. It isn't likely that your foundling
screws will be metric, although an SAE #10-32 is pretty close and might be OK in that application.
Generally, keep your SAE and metric screws apart.
Metric screws with a six-sided head are DIN#933. The standard height nut for it is DIN#934. Nylock
nuts are DIN#985. The most common cap screw ( Round head with an allen broach inside) is DIN#912.
There are other allen head cap screws (various heights and shapes).
Besides your local hardware store, several vendors sell a set of plastic drawers filled with an
assortment of metric fasteners. The same guys who sell assortments of wood screws, SAE screws,
electrical conectors, etc.
