What Are DIN 917 Cap Nuts?
The DIN 917 standard specifies low-profile hexagon cap nuts—also known as hexagon cup nuts—with a domed top that completely covers the exposed bolt threads.
Key Functions:
-
Thread protection – Prevents corrosion, mechanical damage, and injury from exposed threads.
-
Aesthetic finish – Gives assemblies a sleek, professional appearance.
-
Safety enhancement – Reduces snagging hazards in machinery, furniture, and public fixtures.
