║     Types of screws used:                         ║
╚═════════════════════════╝
Full name of common used screws: Phillips machine screws countersunk flat head, Philips DIN 956 (Screwdriver bit: PH2 for M5, PH1 for M3). Hereafter only under the abbreviation CS or Countersunk. 

(Helper for choosing the right length: Each screw is attached to the aluminum profile 5 mm from his total length).

Screw (the most commonly used screws here):

• M5 Countersunk, length: 12, 16, 20, 30, 40mm

• M3 Countersunk, length: 10, 16, 20, 30, 40mm   (10mm also used for MGN Rails)    

     Aliexpress link to M5, M3 phillips countersunk screws: Cloxy (black steel)

Several different screws used:
◦ 2x M5 HEX head cap, length: 40mm (Belt Tensioner)
◦ 4x M5 Half rounded head, length: 12mm - (Bottom of XY gantry joints)
◦ 1x M4 CS, length: 10mm (For rear center of hotbed bottom plate)

Washers:
◦  M5 Small DIN125, 1mm thick, ID: 5.3mm OD: 9.8mm (For pulleys)
◦  M5 Normal size, 1mm thick
◦  M3 (For better attach some stuff like proximity sensor etc.)
