square neck bolt with mushroom flat round and cup head made of Carbon steel/galvanized zinc plated mushroom bolt  
 
       A bolt is a form of threaded fastener with an external male thread. Bolts are thus closely related to,
and often confused with, screws.
      A hex cap screw is a cap screw with a hexagonal head, designed to be driven by a wrench (spanner).
      An ASME B18.2.1 compliant cap screw has somewhat tighter tolerances than a hex bolt for the head height and the shank length. The nature of the tolerance difference allows an ASME B18.2.1 hex capscrew to always fit where a hex bolt is installed but a hex bolt could be slightly too large to be used where a hex cap screw is designed in.

Pellet Machine

This generation of biomass fuel pellet mill with big gearbox, with advantage as follow:

1-all gears flat connecting no taper gears, structure more properly than before,

2-and gears more bigger and tronger than before, roughly no need change the gears ,

3-the motor shaft and the machine main shaft directly connecting into the gearbox, so machine transmission efficiency is more higher than before.
