What kind of wall bolt/anchor will allow me to remove and replace it as many times as necessary?
I am looking to attach a couple of 2×4's flat against a brick wall, however they would only stay there for a few weeks each year. How can I fix them firmly to the wall in such a way that I can put them back each year using the same fixings?
I already have some expanding sleeve anchors if they would do.
(Nothing should be left sticking out of the wall when the wood is not there)
The anchor screws you show are simply too short for that type of shelf. They seem to be designed for anchoring lightweight objects to plasterboard. They are not suitable for plastered brick walls or for shelving that may carry heavy loads like books or heavy ornaments.
I would go out and buy some long screws (say 5cm) and conventional wall-plugs. You will need to drill-out the holes to a wider diameter to suit the wall plugs you buy.
You will probably need to buy a normal length masonry drill bit (probably 7 or 8 mm diameter depending on wall-plug)
Use it in a drill that has a hammer action (a combi-drill will do - borrow one if you don't own one)
If you need to buy a combi-drill - you'll find that wired drills are cheaper and more powerful - much better for drilling into brick.
If money is an issue, buy one from a local Wilco, it will likely last long enough to get this job done :-). B&Q sometimes do a special offer on the halfway-decent Bosch PSB680RE
This is a pop rivet, not a bolt. It can only be removed destructively.
Drill out the center with a drill bit meant for metal (as opposed to a brad point bit, for instance) until the flange come off. Use a bit roughly half the diameter of the flange.
When the flange breaks free, it will get stuck on the tip of your drill bit, which you will then remove with pliers.

Expanding sleeve anchors are probably not the best anchor to use for this - they use the bolt to secure the anchor in the hole. Female drop in anchors would likely work much better, as they fasten independently of the bolt.
Note that they require a setting tool (although some brands I've used include the set tool in the box of fasteners).
