M8 x 80mm Hex Head Bolts | 10-Pack, Grade 8.8, Partial Thread (DIN 931)

M8 x 80mm Hex Head Bolts | 10-Pack, Grade 8.8, Partial Thread (DIN 931)

Secure thick materials and demanding structural assemblies with this 10-Pack of M8 x 80mm Hex Head Bolts. Manufactured to DIN 931 standards from high-tensile Grade 8.8 steel, these long bolts feature a 22mm unthreaded shoulder ('b') for critical shear resistance, followed by a standard 1.25mm pitch thread. The extended 80mm length is engineered for applications requiring deep engagement, such as through timber, heavy brackets, or stacked components, where both shear strength and high clamping force are essential.

Key Features:

• Grade 8.8 High Tensile Strength: 800 N/mm² rating ensures reliable performance under high stress and load.

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

• Extended M8 x 80mm Length: Ideal for fastening thick materials or where a long bolt is required for structural integrity.

• Hexagon Head (13mm AF): Standard head for secure tightening with a spanner or socket.

• Project-Ready 10-Pack: Consistent, high-quality fasteners for professional fabrication, construction, and heavy-duty repairs.
