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.
This selected size is specified with diameter M16, length 60 mm, thread M16, pitch 2 mm.
Sold in multiples of '10 pieces. 1 Box = '10 pieces.
Material, Grade & Strength
A4 (316) stainless steel provides superior corrosion resistance for marine and chemical environments.
Finish & Corrosion Protection
Corrosion resistance is provided by the stainless steel material.
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.
