M8 x 50mm Hex Head Bolts | 10-Pack, Grade 8.8, Partial Thread (DIN 931)

Handle robust fastening applications with this 10-Pack of M8 x 50mm Hex Head Bolts. Manufactured to DIN 931 standards from high-tensile Grade 8.8 steel, these bolts feature a 22mm unthreaded shoulder ('b') for superior shear resistance, followed by a standard 1.25mm pitch thread. This engineered design is ideal for structural connections, machinery, and assemblies where the bolt shank must bear load and ensure precise alignment through an unthreaded hole.

Key Features:

• Grade 8.8 High Strength: 800 N/mm² tensile strength ensures reliability in demanding applications.

• Engineered Shoulder Design (DIN 931): 22mm unthreaded shank provides excellent shear strength and aids in component alignment.

• Versatile M8 x 50mm Size: A common and practical length for a wide range of medium-to-heavy-duty fastening tasks.
