Bolts & Connectors

Strong corrosion resistance U-boltis a fastener shaped like the letter "U". It consists of a screw (with threads) and a nut. It is named after its U-shaped appearance. The threads at both ends can be matched with nuts to fix pipes, components or equipment. The tension generated by tightening the nuts clamps the connected parts to achieve reliable connection.Common materialsCarbon steel: such as Q235 and 45 steel, low cost and high strength, suitable for ordinary industrial and construction scenes.Stainless steel: such as 304 and 316 stainless steel, strong corrosion resistance, mostly used in humid, acid and alkali corrosive environments (such as chemical industry, marine engineering).Alloy steel: such as 35CrMo and 40Cr, good strength and wear resistance, suitable for heavy-duty scenes such as heavy machinery and high-pressure pipelines.

Strong stability anchor bolts are special bolts embedded in concrete foundations. They are mainly used to fix superstructures such as steel structures, mechanical equipment, and towers to the foundation, playing the role of tension, shear, and overturning resistance to ensure structural stability. Its characteristics are that one end is embedded in concrete and the other end is connected to the superstructure through a nut. It is widely used in construction, bridges, electricity, machinery manufacturing and other fields.Steel: Q235 (ordinary strength, used for non-important structures), 45# steel (medium strength), Q345 (high strength, used for heavy structures).Thread specifications: diameter range M12~M100+, length customized according to foundation depth (usually 500~3000mm).

The 7-shaped easy-to-install anchor bolt is a typical type of anchor bolt, named because of its "7" shape (right-angle bending structure). Its structural features are: one end of the screw is a threaded section (used to connect the upper structure), and the other end is vertically bent into a 90° hook, and the overall shape resembles the Arabic numeral "7". This design enhances the anchoring force through the mechanical bite of the bent part and the concrete. It is suitable for the foundation fixation of small and medium-sized structures. It is one of the most commonly used anchor bolt forms in the fields of construction, machinery, and electricity.Q235B (ordinary strength, used for non-important structures, low cost).45# steel (medium strength, used in scenes with large loads after quenching and tempering).Q345B (high strength, used in earthquake zones or heavy equipment, tensile strength needs to be verified.

High-strength anti-seismic bolts are mechanical fasteners made of high-strength steel and used to transmit large loads and earthquake resistance in combination with strict pre-tightening processes. Its core features include:High material strength: The screw material is usually 8.8, 10.9, and 12.9 grade high-strength steel (the number represents the standard value of tensile strength, such as 10.9 grade tensile strength ≥1000MPa, yield strength ≥900MPa).Large pre-tightening force: Apply high-strength pre-tightening force through a torque wrench or special equipment to generate friction on the surface of the connecting parts, thereby transmitting loads (friction-type connection) or directly bearing shear forces (pressure-bearing connection).Severe application scenarios: Mainly used in heavy steel structures, bridges, towers, large-span buildings and other scenarios with extremely high safety requirements.

The cylindrical head welded stud bolt (abbreviated as "weld stud" or "bolt") is a fastener fixed to a metal component by welding. It is commonly used in steel structures, composite floors, bridges and other projects to connect, anchor or transfer loads. The cylindrical head welded stud bolt is a fastener that is quickly fixed to a metal substrate by an arc stud welding process. It does not require drilling and is highly efficient in construction. Its cylindrical head design enhances the anchoring force. It is commonly made of low-carbon steel, stainless steel and other materials. After anti-corrosion treatment such as galvanizing, it can withstand tensile and shear loads. It is widely used in scenes such as steel structure composite floors, bridge steel-concrete connections, equipment base fixation, etc. It has a complete range of specifications with a diameter of 6-25mm and a length of 20-300mm. It supports non-standard customization and strictly follows the GB/T 10433 standard. It is the preferred product for reliable connection in the fields of construction, machinery, shipbuilding, etc.

The hot-dip galvanized lead screw with anti-corrosion design is a threaded rod with surface anti-corrosion treatment using hot-dip galvanizing process. It is made of high-quality carbon steel (such as Q235, 45# steel) with high thread precision and reliable strength. The thickness of the zinc layer formed on its surface can reach 60-80μm, with strong adhesion and good corrosion resistance, suitable for harsh environments such as humidity, acid and alkali. The lead screw is cylindrical as a whole, with full thread or partial thread structure optional, flexible length specifications (usually 0.5-6 meters), and can be tightened or adjusted through matching nuts and gaskets. It is widely used in construction engineering scaffolding support systems, bridge formwork reinforcement, mechanical equipment transmission and positioning, power facility fixation and other fields. With its high strength, corrosion resistance and stable mechanical properties, it has become an indispensable basic connector in industrial and civil scenarios.
