1.Eye screws, also known as sheep eye, sheep eye ring, sheep eye nail, sheep eye bolt, etc., have flat head, pointed head, open head and closed head. The welding methods of eye wood screws are spot welding and full welding.   2. Wide application: Eye wood screws are widely used as accessories for hanging accessories and are also one of the commonly used hardware accessories for architectural decoration.They are used to fix and connect various decorative materials.Eye wood screws are also widely used in ports, electric power, steel, shipbuilding, petrochemicals, mining, railways, construction, metallurgy and chemical industry, automobile manufacturing, plastic machinery, industrial control, highways, large-scale transportation, pipeline auxiliary installation, slope tunnels, shaft management and protection, maritime rescue, marine engineering, airport construction, bridges, aviation, aerospace, venues and other important industries as well as mechanical equipment of infrastructure projects.

Structural Principle Material: Galvanized carbon steel (rust-proof, high strength), some high-end models are stainless steel. Composition: Hex bolt + flat washer + nut + three-piece expansion sleeve (with pre-slit and tightening cone). Principle: When tightening the nut, the bolt pulls the cone, evenly spreading the three sleeve pieces, like three hands firmly “biting” the hole wall. The force is several times stronger than that of plastic expansion tubes, and it can even lock hollow bricks. Mainstream Specifications & Compatible Parameters | Bolt Specifications | Matching Drill Bit Diameter | Common Total Length | Applicable Scenarios | | M6 | 10mm | 40/50mm | Lightweight Hangers, Shelves | | M8 | 12mm | 60/70mm | Towel Racks, Small Appliance Brackets | | M10 | 16mm | 70/80mm | Air Conditioner Outdoor Unit Brackets, Heavy-Duty Shelves | | M12 | 18mm | 90/100mm | Curtain Walls, Heavy Equipment Fixing | Core Advantages Extremely High Load-Bearing Capacity: Taking M10 as an example, the ultimate pull-out force of solid concrete can reach 25kN. Calculated with a safe load-bearing capacity factor of 3-4, it can withstand tens of kilograms of tensile force; reliable anchoring can also be achieved with hollow bricks/perforated bricks (plastic expansion tubes are basically ineffective on hollow bricks). Widely applicable wall surfaces: Suitable for concrete, red bricks, hollow bricks, lightweight bricks, foam bricks, and marble/stone, earning it the nickname “hollow brick nemesis.” Easy to install and remove: Simply loosen the nut to remove it; the sleeve is recyclable and reusable (unlike plastic expansion tubes, which are generally disposable).

1. TAM Anchor is a special threaded connector, mainly used to fasten parts that need to withstand large tensile forces, such as bridges, buildings, etc. 2. Application:Tam anchors are widely used in many industries. In the auto maintenance industry, they are often used to fix and install lifts. In the construction industry, tam anchors can be used to fix various building accessories. In the hardware manufacturing industry, it can be used with other types of expansion bolts to fix various building components. Tam anchors can also be used in other occasions where pipes or equipment need to be fixed.

Hollow wall anchor bolts, also known as hollow wall anchors or hollow expansion screws, are mainly used in hollow walls, gypsum boards, fiberboards, plastic boards, wooden boards and other walls. They are light load anchor bolts. The heads and nuts at both ends are of two types: “welded” and “integrated”. They can be directly installed with an electric screwdriver or pulled with special tools. Installation method: 1. The teeth on the head of the casing can be embedded in the hollow substrate, which can effectively prevent the casing from rotating in the hole during installation. 2. After installation, the expansion arm is opened behind the hollow substrate to form a large radius and large area of ​​contact, providing a reliable anchoring effect. 3. The matching screws can be easily removed, and the mounting parts can be repeatedly disassembled and assembled without affecting the anchoring effect. 4. Ordinary flat-blade or cross screwdrivers can be used for installation. If special installation tools are used, it can be more suitable for large-scale professional use occasions.

Wedge anchors are mainly used for heavy-duty equipment such as pipe gallery hangers, seismic support hangers, glass exterior walls, elevator brackets, shelves, and railings. In addition, it is also suitable for concrete and dense natural stone, metal structures, metal profiles, bottom plates, support plates, brackets, machine beams, beams, brackets, etc.

1. Tire wire anchor is a kind of fastener often encountered in daily life, mainly used for fixing. 2. Application: Tire wire anchors are usually used in heavy-load facilities with high tension and shear forces. They are suitable for concrete and dense natural stone, metal structures, metal profiles, base plates, support plates, brackets, railings, windows, curtain walls, machines, beams, girders, brackets, etc.

The function of the forced expansion fastening bolt is to expand the expansion sheet by knocking, thereby fixing the object on the wall.

1.Installation steps: ① Punch a hole ② Hammer the casing into the air ③ Screw the screw into the wall anchor ④ Installation is complete 2.Scope of application: Suitable for home decoration, industrial building materials, medical equipment, etc. 3.Product features: small and light, easy to carry, easy to take, strong and durable
