Hexagon High Tensile Bolts - Galvanised

Hexagon high tensile bolts

• Galvanised
• Grade 8.8, high tensile
• Part threaded
• Din 931

Threaded portion of the bolt is calculated by:
Bolt length upto 125mm: 6 + (2 x bolt diameter)
Bolt length from 130mm: 12 + (2 x bolt diameter)
Bolt length from 200mm: 25 + (2 x bolt diameter)
e.g M8 x 120, threaded part is 6 + (2 x 8) = 22mm
