M6 x 50mm Hex Head Bolts | 10-Pack, Grade 8.8, Partial Thread (DIN 931)

M6 x 50mm Hex Head Bolts | 10-Pack, Grade 8.8, Partial Thread (DIN 931)

Secure assemblies with enhanced shear strength using this 10-Pack of M6 x 50mm Hex Head Bolts. Manufactured to DIN 931 standards from high-tensile Grade 8.8 steel, these bolts feature an 18mm unthreaded shoulder ('b') followed by a standard 1mm pitch thread. This design provides greater resistance to shearing forces and allows for precise location within a joint, making them ideal for machinery, brackets, and applications where the bolt shank bears direct load.

Key Features:

• Grade 8.8 High Strength: 800 N/mm² tensile strength for reliable performance in demanding conditions.

• Partial Thread with Shoulder (DIN 931): 18mm unthreaded shank increases shear resistance and aids alignment.

• Versatile M6 x 50mm Size: Practical length for medium-thickness materials and structural connections.

• Hexagon Head (10mm AF): Standard head for easy tightening with a spanner or socket.

• Convenient 10-Pack: Consistent quality and ample quantity for projects and repairs.
