FAQs
What does DIN 916 mean?
DIN 916 is a German standard that specifies the dimensions and tolerances for a particular type of grub screw, often referred to as a 'cup point' set screw.
What are grub screws primarily used for?
Grub screws, also known as set screws, are headless screws used to secure an object within or against another object by exerting pressure with their point, typically when screwed into a threaded hole in one of the objects.
What is the benefit of the black finish?
The black finish, often a result of black oxide treatment, provides a degree of corrosion resistance and a non-reflective, neat appearance, making them suitable for applications where aesthetics are a consideration.
Are these screws magnetic?
These grub screws are typically made from steel, which is a ferrous metal and thus magnetic.
Can I use these for high-vibration applications?
While grub screws provide secure fastening, for extremely high-vibration applications, consider using thread-locking compounds in conjunction with the grub screw for enhanced security.
What is the difference between M4 x 8mm and M5 x 5mm?
M4 x 8mm refers to a grub screw with a metric thread diameter of 4mm and a length of 8mm. M5 x 5mm has a thread diameter of 5mm and a length of 5mm.
How should I store these screws to prevent rust?
Store them in a dry environment, ideally in their original packaging or a sealed container, to minimize exposure to moisture.
Troubleshooting
Grub screw not tightening properly
Ensure you are using the correct metric thread size. Check that the mating component's thread or bore is clean and free of obstructions. Verify that the hex key is the correct size and fully engaged in the screw head.
Stripped screw head
If the hex head is stripped, try using a slightly larger hex key or a specialized screw extractor tool. For minor stripping, a firm grip with pliers might help. In severe cases, the screw may need to be drilled out.
Screw head is too small for the tool
You may be using the wrong size hex key. Double-check the metric size of the grub screw and use the corresponding imperial or metric hex key.

Setup, Compatibility & Care Instructions
Setup: To use these grub screws, select the appropriate size (diameter and length) for your application. Ensure the mating components have corresponding threaded or unthreaded holes. Insert the grub screw into the designated hole and use a suitable hex key (Allen key) to tighten it. Apply sufficient torque to secure the components without stripping the screw head or damaging the threads.
Compatibility: These screws are compatible with any components featuring the correct metric thread size. They are designed to fit standard hex sockets (Allen heads) and are particularly useful in mechanical assemblies, machine building, and DIY projects.
Care: Store the grub screws in their original box or a suitable compartmentalized organizer to prevent loss and contamination. Keep them in a dry environment to minimize the risk of corrosion, although the black finish offers some protection. Clean any dirt or debris from the screw and the mating threads before installation to ensure a secure fit and prevent damage.
