Hex Bolts

Hex bolts are also commonly known as hex head cap screws or machine bolts.  
Our hex bolts are available in Grade 2, Grade 5, & Grade 8 in Zinc Plated, Grade A307 (comparable to Grade 2) in Hot Dipped Galvanized, and in 18-8 Stainless Steel.
For higher strength hot dipped galvanized bolts see our Structural Bolts.

The majority of these hex bolts are not fully threaded, they are generally threaded 3/4" to 2" of the end of the bolt.
For fully threaded hex bolts please see our Tap Bolts.

 

 
Select a Grade & Finish     Hex Bolt          
 
Low carbon steel, best for general use applications (comparable to Grade 2). Zinc Plating is the most common finish and provides moderate protection against corrosion.
Medium carbon steel, for higher strength applications. Zinc Plating is the most common finish and provides moderate protection against corrosion.
Tempered medium carbon alloy steel, used in high strength and hardness applications.
Hot dipped galvanized fasteners are much more corrosion resistant than zinc plated fasteners. Galvanized bolts can only be used with galvanized nuts due to the thickness of the coating.
Stainless steel has the highest corrosion resistance for outdoor and marine use.
Plain Finish Steel with no corrosion resistance. Color ranges from grey to carbon black. Will come with a light oil coating. We do not stock this coating, all sizes are sold in bulk quantity only to be drop shipped.
