Socket Head Cap Screw ISO 4762 DIN 912
Cylindrical head screw with hex socket for applications where high mechanical strength, tightening precision and a compact design are required.
What is the ISO 4762 / DIN 912 screw?
The ISO 4762 screw, also known as DIN 912, is a socket head cap screw with a cylindrical head and hex socket. Its geometry allows high tightening torque to be applied using a hexagonal tool.
It is a common standard in machining, automation, tooling, molds, industrial machinery and compact mechanical structures where repeatability and joint reliability are essential.
Cylindrical head
Provides a robust bearing surface and strong mechanical capacity in demanding assemblies.
Hex socket
Enables precise tightening with an Allen key or controlled tool.
High strength
Widely used in assemblies subjected to load, vibration or repeated work cycles.
Main characteristics
Common materials and finishes
Materials
- Carbon steel · grades 8.8, 10.9 and 12.9
- Stainless steel · A2 and A4 grades
- Alloy steel · heat treated
Finishes
- Black oxide · industrial technical finish
- Zinc plated · surface protection
- Natural stainless · corrosion resistance
Material and finish selection should be based on load, working environment, corrosion, temperature, tightening torque and traceability requirements.

Common industrial applications
Advantages over other screws
Higher tightening torque
The Allen drive allows more torque to be transmitted than slotted solutions or less precise drive systems.
Better alignment
The internal hex socket supports centered, clean assembly and compatibility with controlled tools.
Less slipping
Reduces the risk of tool slipping during tightening when the correct key is used.
Technical appearance
The cylindrical head provides a clean industrial look in visible assemblies.
