Description
Socket Csk Machine Screws BZP – DIN 7991 (Metric Coarse)
Our Socket Csk Machine Screws BZP – DIN 7991 are engineered for applications where a flat, snag-free surface is essential. These screws feature a hexagonal socket drive, allowing for higher torque compared to standard Phillips or slotted heads. Finished with Bright Zinc Plating (BZP), they offer a clean, shiny appearance and reliable protection for indoor environments.
Key Features
- Flush Installation: The 90-degree countersunk head sits perfectly level with (or below) the material surface, preventing snags and improving safety.
- High-Tensile Grade: Supplied in Grade 10.9 steel, these fasteners provide significantly more strength and load-bearing capacity than standard hardware-store screws.
- Precision Drive: The internal hex socket (Allen drive) reduces the risk of “cam-out” or slipping, protecting the finish of your workpiece during installation.
