Full Thread SS Coach Square Neck Round Mushroom Head Bolt

Product Description

Product Description

Carriage bolts, also known as round head square neck bolts, are easily recognizable due to their unique head design. The head is round, and beneath it is connected to a square neck. This design effectively prevents the bolt from rotating during the connection process, ensuring the stability and reliability of the fastening.

Product Features

 

Head Design	The head is round, with a square section underneath. This design effectively prevents the bolt from rotating when tightened, ensuring the firmness and stability of the connection.
Fastening Performance	The threads are precisely machined, providing a good biting effect, capable of withstanding large tensile and shear forces, ensuring a tight connection at the joint and being less likely to loosen.
High-Quality Material	Made of high-quality carbon steel or stainless steel materials, it has excellent strength and corrosion resistance, suitable for different working environments and extending the service life.
Surface Treatment	The surface is treated by processes such as galvanizing, chromium plating, or passivation, which enhances the bolt's antioxidant ability and aesthetics, and also improves its performance in humid or harsh environments.

Products Material

Materials	Characteristics	Advantages
Carbon Steel	Mainly composed of iron and carbon, and the carbon content affects its hardness and strength. Usually, the carbon content is between 0.05% and 2%.	1.High strength 2.good processing  performance 3.Easy to conduct manufacturing   4.Low cost.
Stainless Steel	The main alloy elements include chromium (Cr), nickel (Ni), molybdenum (Mo), etc., and the chromium content is generally not less than 10.5%. Common ones include 304 stainless steel (with about 18% chromium and 8% nickel) and 316 stainless steel (with 16% - 18% chromium, 10% - 14% nickel, and 2% - 3% molybdenum), etc.	1.Excellent corrosion resistance 2.Good heat resistance and low-temperature toughness 3.High surface finish
