The Professional Grade Hexalobular Head Flange Bolts are usually cheaper than many other specialized fasteners. This is because they are mass-produced, so the cost per bolt is lower. The built-in flange is like a washer, so you don't need to purchase a separate washer - this helps save time and money in the project.
When you place a larger order (e.g. 10,000 units or more), the unit price of the product will generally be reduced by 5% to 15%. They are sturdy and practical, and are a highly cost-effective choice for manufacturers who want to reduce costs without sacrificing quality.

The Professional Grade Hexalobular Head Flange Bolts are usually made of carbon steel, stainless steel (such as 304 or 316), and alloy steel. Carbon steel bolts are a more economical choice for daily use. This stainless steel bolt has a good anti-rust effect and is very suitable for use in places such as open air or the ocean. In response to the needs of use in harsh industrial environments, alloy steel bolts are generally subjected to heat treatment to increase their strength so that they can work reliably under heavy load conditions.
The material you choose will affect the lifespan of the bolts, the weight they can bear, and their performance when exposed to moisture or chemical substances.
