DIN 933 - Bolt Dimension

"DIN 933 is a German grade which is now obsolete and has been preplaced by ISO 4017, however in some places DIN 933 is still used and the dimensions described below in DIN 933 are similar to ISO 4017.
We have all drawings with grade 8.8, 10.9, SS316, A2-70, A2-80, A4-70, A4-80 & size from M16 to M64. The Drawing have all specification of bolts like weight, grade, size of bolt like (Shank length, threading length, Shank diameter, head flat & corner, Head thickness, threading diameters etc.). Also we have all bolts weight chart according to its length & diameter."

Dimensional Standard of Bolts per DIN 933

• For hot-dip galvanized nuts, the dimensions apply before galvanizing.
• P is the pitch of thread.
• dw, max. = actual
• β = 15⁰ to 30⁰
• Incomplete thread u = 2P
