The Performance Optimized Hexalobular Head Flange Bolts come in various surface treatments to meet different usage requirements. Common options include galvanization (silver color), which helps prevent rust indoors; and hot-dip galvanization (gray color), which is more suitable for outdoor or humid environments. Black oxidation treatment not only gives the workpiece a calm dark appearance, but also effectively reduces the surface friction coefficient. It is an ideal surface treatment solution for mechanical equipment that focuses on appearance. Some suppliers also offer customized color services through powder coating, so companies can match the bolts with their own equipment or brand.
We deliver the Performance Optimized Hexalobular Head Flange Bolts through various reliable methods to ensure their prompt arrival and our ability to respond flexibly.

The Performance Optimized Hexalobular Head Flange Bolts can be customized in size according to your requirements. Usually, you can request different thread sizes (from M5 to M20 or larger), length, bolt head width, and thread type (metric or imperial). Customized sizes help ensure that these bolts can function properly in special circumstances (such as unique machinery or custom installations).
When placing an order, please provide accurate dimensional information such as head height and flange thickness. This will help us match the appropriate bolts to ensure that they meet your part assembly and project needs.
