Description

The M8x30 countersunk socket head screw, black, 10.9, DIN7991 is a reliable fastener for structures where you require a completely smooth surface without protruding heads. This screw features a partial thread with a length of 22 mm and is designed for high mechanical loads thanks to its strength class 10.9 steel.

Tightening is performed using an internal hexagon for a key size of 5 mm, which ensures a safe and precise transfer of torque. Due to the unfinished surface, we recommend protecting the screw from direct moisture or applying it in covered assemblies and areas intended for subsequent painting.

Key Technical Parameters

Dimensions according to DIN 7991 (ISO 10642): Guarantee absolute shape accuracy and easy interchangeability.
Countersunk head (height 4 mm): Ensures trouble-free flush mounting with the plane of the clamped part.
Partial thread: Increases the strength of the shank and allows for more efficient drawing of two materials together.
Strength class 10.9: Provides excellent shear and tensile resistance for highly stressed joints.

During installation, ensure proper pre-drilling and countersinking of the hole so that the M8x30 countersunk socket head screw, black, 10.9, DIN7991 can seat securely. This will prevent unwanted stress in the material and facilitate any future disassembly and machine maintenance.
