Description
Overview
DIN 912 (equivalent to ISO 4762) defines a hexagon socket cap screw with a cylindrical head and full thread. The internal hex drive allows high tightening torque while requiring minimal clearance around the head, making it one of the most widely used fasteners in machinery and precision engineering.
Sold per piece. Screwman code CAP102412H.
Material, Grade & Strength
Grade 12.9 is an ultra-high strength alloy steel property class with approximately 1200 MPa tensile strength and 1080 MPa yield strength, widely used for precision machinery and demanding mechanical assemblies.
Finish & Corrosion Protection
Plain finish fasteners are intended for protected environments.
Typical Uses
Commonly used in machine tools, moulds, dies, automation equipment, fixtures, hydraulic systems and industrial machinery.
Technical Tips
- Use the correct hex key or socket bit.
- Counterbored holes provide full seating.
- Follow recognised torque charts for the selected size and grade.
Selection Advice
Select DIN 912 where high tightening torque and a compact head design are required.
Frequently Asked Questions
What is the difference between DIN 912 and ISO 4762? ISO 4762 replaced DIN 912 internationally and the dimensions are generally interchangeable.
