Steel Bolt Manufacturer In China

Ningbo Teng Qi Fasteners Co., Ltd is a leading steel bolt manufacturer in China. A steel bolt is a type of fastener made primarily of steel and designed for joining or fastening two or more objects together. It typically consists of a threaded cylindrical shaft (the shank) with a head at one end. The head can take various shapes, such as hexagonal (hex head), square, round, or flat, depending on the specific application and the type of bolt. Steel bolts are commonly used in construction, manufacturing, automotive, and countless other industries due to their strength and durability. They come in various sizes, lengths, and grades to suit different applications. Bolts are often paired with nuts and washers to create a secure and reliable connection.

FAQ about Steel Bolt:

1.How to store steel bolts to prevent corrosion?

Store steel bolts in a dry, cool place and keep them away from moisture to prevent rust. Using proper containers or sealable bags can help.

2.What is the difference between stainless steel bolts and regular steel bolts?

Stainless steel bolts are corrosion-resistant and well-suited for applications where rust is a concern. Regular steel bolts may require additional coatings for similar protection.

3.Can steel bolts be used in outdoor applications?

Yes, steel bolts can be used outdoors, but they may require a corrosion-resistant coating like galvanization for extended durability in harsh environments.

4.What is the difference between imperial and metric bolts?

Imperial bolts use inches and threads per inch (TPI) for sizing, while metric bolts use millimeters and thread pitch. Metric bolts are more common in many parts of the world.
