DIN933 M5 M10 M12 M8 A2-70 Stainless Steel Hex Bolts

Hexagon bolts are divided into two types: outer hexagon bolts and inner hexagon screws. According to the force mode of connection, there are ordinary and reaming holes. Bolts for reaming holes should fit the size of the holes and be used when subjected to transverse forces. Hexagonal heads, round heads, square heads, countersunk heads, etc. Generally countersunk heads are used where the surface is required to be smooth after joining, because countersunk heads can be screwed into parts. Round heads can also be screwed into parts. The tightening force of square head can be larger, but the size is large. The hexagonal head is the most commonly used. In addition, in order to meet the needs of locking after installation, there are holes in the head and holes in the rod, which can make the bolt not loose when it is vibrated.
