Sirius 10.9 Grade Socket Countersunk Screws BZP M4 16mm Pack of 1

These high-tensile socket countersunk screws deliver exceptional clamping strength while sitting flush with the surface, making them the ideal choice for demanding mechanical assemblies where both performance and a clean finish are required. Manufactured to grade 10.9 specification, each screw offers superior load-bearing capacity compared to standard grade fasteners, ensuring reliable fastening in high-stress applications such as automotive, machinery and structural work. The countersunk head design allows the screw to sit completely below the material surface, preventing snagging and providing a professional appearance, while the socket drive enables precise torque control during installation.

- Grade 10.9 high tensile steel for maximum strength and durability

- Countersunk head for a flush, low-profile finish

- Bright zinc plated (BZP) finish for good corrosion resistance

- M4 thread size with 16mm length suitable for a wide range of fixings

- Socket (hexagon) drive for reliable tool engagement and reduced cam-out

- Supplied as a pack of 1 for single-use or replacement requirements

Whether you are working on precision engineering projects or carrying out critical repairs, these screws offer the consistent performance and reliability you need.
