RS PRO Plain Steel Hex Socket Countersunk Screw, M8 x 30 mm, DIN 7991, Grade A, 292-502

The RS PRO 292-502 is a plain steel hex socket countersunk screw engineered for demanding applications requiring secure fastening and a flush finish. This fastener features an M8 metric thread and a 30 mm length, making it suitable for use in industrial machinery, panel assemblies and equipment repair where precision and strength are critical.

Its countersunk head allows the screw to sit level with or below the surface of the workpiece, minimizing snagging and providing an attractive finish. The hex socket drive enables installation and removal with standard Allen keys, ensuring secure torque transmission during assembly and maintenance. Constructed from robust Grade A steel with a plain finish, this fastener offers excellent mechanical strength, making it more resilient than standard 8.8 grade alternatives. It is produced to comply with DIN 7991 standards for socket countersunk screws, ensuring dimensional accuracy and reliable fit in compatible sockets.

With a nominal tensile strength of 1040 N/mm² and yield strength of 940 N/mm², this screw is suitable for light to medium duty fastening where both strength and appearance matter. Its black finish provides both corrosion resistance and a quality appearance, fitting seamlessly into applications such as machinery fabrication, panel building, machine tooling, fastener repairs, and interior joinery. The hex socket feature allows for easy tightening or loosening without damaging the head, making it ideal for repeated assembly and disassembly operations.

Typical uses extend to sectors including electronics, automotive production lines, security enclosures, woodworking, and facilities maintenance. This fastener can be used anywhere a secure and reliable flush mount solution is required, especially in equipment and assemblies where neat, snag-free surfaces are desirable.

The RS PRO 292-502 plain steel hex socket countersunk screw is a versatile addition to any professional or maintenance toolkit, offering industrial-grade reliability and finish.
