1.The head of the bolt is spherical with holes, the spherical surface is smooth, the installation of the Eye Bolts is relatively simple, and it is often used for the occasion of opening and disassembling or the tooling assembly.The thread precision of the Eye Bolts is high, which can improve the quality of the whole workpiece as an accessory. 2.Eye Bolts are widely used in: low temperature and high pressure valves, pressure pipelines, fluid engineering, oil drilling and production equipment, oilfield equipment and other fields, often in the disconnecting occasions or tools such as the valve industry, folding bicycles, strollers are used, because the use of Eye Bolts is convenient and fast, and the use of matching nuts plays the role of connection fastening, a wide range of applications.

1It is mainly used to fix pipes such as water pipes or sheet springs such as automobiles, and its material characteristics, density, bending strength, impact toughness, compression strength, elastic modulus, tensile strength, temperature resistance and color are determined according to the use environment 2. U-type is generally used in trucks, it is used to stabilize the chassis and frame of the car. For example, leaf springs are connected with U-bolts. U-bolt is widely used, the main uses: construction installation, mechanical parts connection, vehicles, ships, Bridges, tunnels and railways.

DIN 933 is the standard for full‑thread hexagon head bolts, one of the most widely used general‑purpose fasteners in construction, machinery, automotive and industrial assembly. The bolt features a hexagonal head for easy torque installation with wrenches, and full‑length thread design to meet flexible fastening requirements. Material: Carbon steel (C1022 / 4.8 / 8.8 / 10.9 / 12.9 grade), Stainless steel A2‑50, A4‑80 Surface finish: Electro‑galvanized (white/yellow zinc), black oxide, hot‑dip galvanized, Ruspert coating Thread type: Metric coarse thread (M5–M48), pitch conforms to DIN standard Head width across flats: Strictly per DIN 933 standard, consistent with DIN 934 nut matching Thread: Full thread, full‑length threading for complete engagement Length range: 8mm–300mm, customized sizes available Full‑thread structure, flexible connection, suitable for various thickness assembly High precision thread, perfect matching with DIN 934 hex nuts Stable mechanical performance, anti‑loose, durable, strong load‑bearing capacity Multiple anti‑corrosion treatments for indoor and outdoor applications Application Scenarios Widely used in mechanical equipment, steel structure engineering, building construction, electrical installation, automotive parts, pipeline fixing, furniture hardware and general industrial assembly.

DIN6921 flange bolts are widely used in various mechanical equipment and engineering structures, especially in application scenarios facing high tension or strong shear working conditions. Its design features include high strength, high precision, corrosion resistance, and mature technology, ensuring the safety and quality of the connection.

The T-bolt can be directly placed into the aluminum profile groove, and it can automatically position and lock during installation. It is often used in conjunction with flange nuts and is a standard matching connector for installing corner pieces. It can be selected and used according to the width of the profile groove and different series of profiles.
