DIN 933 has been withdrawn like many DIN standard parts, and delivery is to DIN EN ISO 4017. In purchasing, the screw is still called DIN 933. Both numbers are listed here side by side, so you do not have to look them up before ordering.
The list is not a complete catalogue of standard parts, which would go beyond the scope of this page. It shows what we supply regularly. If your number is missing, for example for fitted bolts, spacer bolts, thread-forming screws, grooved pins to DIN 1473 and ISO 8740 or rivets to DIN 7338, please send us your requirements or the standard you have on file.

Rework on standard parts
A standard part is rarely exactly the component you need. Whatever is missing is added before delivery.
Drilling
Grinding
If a dimension has to be tighter than the standard allows, the component is ground to your dimension.
Milling
Slots, spanner flats and shoulders are milled into the standard part afterwards.
Surface
The surface is brought to the quality that your mating part and your seal require.
Coating
Zinc-plated, black oxide or zinc flake. You decide which coating your component carries.
Hardening processes
If your component has to carry more load, it is hardened and then tested for hardness.
Questions
What buyers ask about standard parts.
01
What are standard parts, and which ones do you supply?
Components whose dimensions, tolerances and properties are defined by a DIN, EN, ISO or ANSI standard. We supply screws, nuts, washers, threaded bolts, threaded rods DIN 976, pins, springs and rivets such as solid rivets, semi-tubular rivets, step rivets or rivet pins. Press-in nuts are part of our product range. Enquire about the version you need. We supply complete HV assemblies comprising bolts, nuts and washers.
02
In which sizes are standard parts available from NORM+DREH?
From M1.2 to M200, lengths from 3 to 3,000 mm. Threaded bolts, studs DIN 938 and DIN 939 and double-end studs also in special lengths. Property class, material and surface finish to standard or specification, for example steel or stainless steel A2 and A4.
03
Is my DIN number still valid?
Often not. In the changeover from DIN to ISO, DIN 915 was replaced by ISO 4028, DIN 916 by ISO 4029 and DIN 933 by ISO 4017. For DIN 933, only the width across flats changes in M10, M12, M14 and M22. You can still order by the old number.
04
What happens if a standard part needs rework?
Then it is reworked: drilling, grinding, milling, surface finish, coating or hardening. On request, thread locking is added from a single source. Send us the drawing with the standard and the deviation, and we will tell you what is feasible. Precote, zinc-nickel and zinc flake remain fully available.
