The Unifix Socket Head Cap Screws DIN 912 are high-strength fastening solutions designed for professional and industrial engineering tasks requiring a secure and reliable hold. These silver-finish screws feature a standard socket head design for efficient installation using hex keys, making them ideal for assembly work where limited access prevents the use of standard wrench-driven bolts. While highly durable, users should note that these require a compatible hex key toolset and proper torque application to avoid over-tightening or damaging the socket recess.

DIN 912 is a German industrial standard for the dimensions and specifications of hexagon socket head cap screws.
While durable, their suitability depends on the specific environmental conditions. Ensure they are compatible with the material they are being fastened into to avoid galvanic corrosion.
Yes, but use a low-torque setting and a high-quality hex bit to avoid stripping the socket head.
Each box contains 200 units.
These specific units feature a silver-coloured finish.
The primary advantage is the ability to install the screw in tight, recessed areas where a standard wrench cannot reach.
Verify that you are using the correct metric size hex key and that it is not worn out. Ensure the key is fully inserted into the socket.
Back the screw out and check for debris in the threaded hole or potential cross-threading. Ensure the screw size matches the existing thread pitch.
Use a screw extractor tool or a slightly larger torx bit hammered gently into the head to gain grip for removal. Replace the damaged screw immediately.
To install these screws, ensure your hex key size corresponds exactly to the screw's socket dimensions. It is recommended to use a high-quality hex key to minimize the risk of slipping during high-torque applications. When fastening into threaded holes, start the threads by hand to prevent cross-threading. For maintenance, keep the screws clean and free of debris, especially in the socket head, to ensure a solid tool engagement. If used in exterior or corrosive environments, check periodically for signs of oxidation and apply appropriate anti-seize lubricants if required by the assembly specifications.
