⚡ At a Glance
- • Holding Strength: High tensile steel Grade 8.8 combined with a fully threaded shank for reliable clamp force
- • Best for: Mechanical assembly, general maintenance and machinery repairs needing standard metric fasteners
- • Not ideal for: Applications that require stainless steel fasteners for superior corrosion resistance
M7 x 80mm fully threaded hexagon head screws made to DIN 933 in Grade 8.8 steel with zinc coating. Wrench size 11mm and 1mm pitch match standard M7 nuts and assemblies.
Secure clamping - with High-Tensile Grade 8.8 steel
Grade 8.8 denotes a higher tensile strength classification for metric fasteners, while the fully threaded shank spreads load along the entire length. DIN 933 designation confirms the hexagon head, fully threaded form factor.
Stronger steel and full threading deliver dependable clamp force, reducing loosening under vibration. Suitable for assemblies where consistent torque retention matters.
Accurate fit and torque control - with M7 thread and 1mm pitch
Thread diameter of 7mm and a 1mm pitch define compatibility with standard M7 nuts and tapped holes. The specified wrench size of 11mm ensures a predictable spanner fit for correct torque application.
Consistent thread geometry and a matched spanner size make tightening predictable, so assemblies sit true and fasteners do not overrun threads.
Reduced surface corrosion risk - with zinc coating
Zinc coating provides a sacrificial layer over the steel substrate to slow surface oxidation in typical workshop environments. The protective finish is common for general-purpose fasteners.
Zinc-plated finish helps parts last longer in non-marine conditions, keeping joints presentable and extending service life in everyday use.
