In the mounted object (pull-up bar) there are 4 holes and in the kit there are 4 such anchors.
One type has a metal sleeve, there's decent gap between internal bolt and the sleeve - it moves freely, it has nut on the end. 10mm inscription on the sleeve.
The other has plastic sleeve with pimples outside, very tight: I can't screw in the screw with hands. Inscriptions: 12 and 10x60. They going to go into brick/concrete wall. Thought one guy tells that blue ones are drywall anchors.
There 3 things I would like to clarify:
1. Sizes of drill bits
It seems I need 2 bits. I've seen a controversial info on the Internet: that the hole should be the same size as the sleeve, also that it should be bigger.
2. What way I should put them inside Аre sleeves supposed to be inserted with hands or with hammer? What about internal parts (blue are very tight - may be a hammer)?
3. Sequencing. Metal sleeves seams supposed to widen: entirely or only at the ends? Should I insert the sleeve first and then the shaft? With a hammer? One guy told be to insert the entire thing.
