Lot de 10 boulons d'expansion hexagonaux, M8x70mm, en fer galvanisé coloré et en acier au carbone, pour usage extérieur

[Multi-purpose] - Concrete brick expansion screws are suitable for fixing concrete and masonry, as well as various heavy installations. They are widely used in construction projects and home maintenance, such as fences, canopies, concrete anchors, building walls, indoor bathrooms and kitchens, air conditioners, ceilings, doors, lighting, advertising billboards, TV wall installations, outdoor railings, etc.
[Expansion Bolts] - Our air conditioner wall fixing screws are made of galvanized iron carbon steel. These bolts are rust-proof and corrosion-resistant, have high hardness, are strong and not easily broken, can firmly fix heavy objects, and have a long service life.
[Advantages] - The sleeve fasteners make the concrete wall surface smooth and burr-free. The threaded bolts are designed to bear force evenly, providing a reliable connection and firmly fixing solid surfaces such as concrete and masonry. Expansion bolts come with nuts and washers for easy installation.
[Installation] - By tightening the bolt, expansion occurs. The bolt pulls the conical cone, causing the sleeve to expand towards the hole wall, achieving a stable fixing effect.
