The Dome Head Bolts have a semi-circular shape and smoothly transition with the connecting components after installation. Its design is particularly suitable for scenarios with strict appearance requirements, such as high-end furniture, electronic product casings, precision instruments, etc. It ensures connection strength and enhances overall aesthetics. The design of the hexagonal groove allows for a larger contact area between the wrench and the screw, resulting in more uniform torque transmission.

Blue White Zinc Bumper Bolts and Nuts have become an indispensable "invisible guardian" in modern industry due to their unique round head and square neck design, excellent mechanical performance, and wide applicability. The carriage neck bolt redefines the value standard of carriage bolts with craftsmanship and technological innovation.

The galvanizing treatment of blue and white zinc on the Flat Head Socket Cap Screw not only gives the screw a silver white metallic luster, but also gives it excellent corrosion resistance. According to salt spray test data, the blue and white zinc coating can withstand more than 720 hours in a 5% neutral salt spray environment, which can effectively extend the service life of the screw and reduce equipment maintenance costs.

The head of the plum blossom sinking machine nail adopts precision cold heading forming technology, with a smooth surface without burrs and rounded edges. The head diameter and countersunk depth have been optimized ergonomically to ensure torque transmission efficiency while achieving visual simplicity and aesthetics. Adopting a plum blossom groove structure and paired with a plum blossom wrench, the torque transmission efficiency is increased by 40%, and the installation speed is fast.

Jinghong supplier specially provides Customized Hexagonal Plug Bolt, with a hexagonal head that is easy to tighten using tools such as wrenches, and the surface is treated. The Dacromet coating can still maintain its protective performance in a high temperature environment of 300 ℃, and its thermal properties far exceed traditional galvanized coatings. At the same time, the coating can resist long-term corrosion such as ultraviolet rays and acid rain.
