Hex Bolt

Hex bolt is a bolt with a hexagonal or six sided head, which is generally called hex head cap screw. A hex cap screw applied to anywhere is actually manufactured with tighter tolerances. In addition, it features a washer surface directly under the head which creates a better seal.

The bolt picture is a general representation rather than an actual picture of the product you will receive. Besides, thread will vary with the individual bolt size and dimension. However, we should also abide by ISO standard for threads that is length being twice the diameter of the bolt plus half an inch.

Hex bolt consists of hex head and screw with the external thread of the cylinder. It can be applied to construction, machinery, hardware, kitchen stoves and other places, usually used in conjunction with nuts.

Hex bolt is popular in this series of products, featuring hexagonal structure. Thus, it is very convenient for users to tighten or loosen bolt or nut only by ordinary adjustable wrench.

In view of differences of product surface treatment, hex bolt can fall into various types of bolt, such as self color type, galvanized type, yellow zinc plating type, hot dip galvanized type and Dacromet type. Among them, the price of self color bolt is the cheapest and others provide better corrosion resistance.

The product specification we provided is M6 to M64 in metric series and 1/4" to 2-1/2" in inch series. Of them, small diameter of bolt has small strength, mainly used for the connection with non stress carrying parts. In addition, large diameter of bolt, also called heavy bolt, has high demand for the mechanical performance of product. After the molding process and heat treatment, our product features high strength, excellent toughness and the ability to link heavy structure.
