Quick Specifications
Key Features
Reduced Head Height
Head height is approximately 60% of standard DIN 912, allowing installation in tight spaces.
Hex Socket Drive
Retains internal hex (Allen) drive for reliable torque transmission despite smaller head.
Same Thread as DIN 912
Identical thread dimensions to standard socket caps — fits same tapped holes and nuts.
Precision Applications
Ideal for jigs, fixtures, and assemblies where head protrusion must be minimized.

Property Classes
When to Use DIN 7984
💡 Low Head vs Standard Socket Caps
Choose DIN 7984 low head socket cap screws when:
- Limited clearance — parts must pass over the head
- Thin materials — counterbore depth is restricted
- Weight critical — every gram counts (aerospace, racing)
- Aesthetic preference — lower profile appearance desired
Note: Smaller hex key size means reduced torque capacity compared to DIN 912.
