Fasteners
Hex Head Bolts — DIN 933 / ISO 4017
Fully threaded hex bolts in property classes 8.8 to 12.9, cold- or hot-forged and heat treated in house.
SpecificationsThe integrated flange distributes clamp load over a larger bearing area, and the serrated face bites into the mating surface to resist loosening under dynamic load. This removes a washer from your bill of materials and one step from your assembly line — the saving is usually larger than the price difference on the nut itself.
