  • Excellent high temperature stability
  • Very oxidation and carburization resistant to 2100°F
  • Good resistance to thermal shock and quenching
  • Alloy 330 hex head cap screw features and benefits

Alloy 330 hex head cap screws are specifically designed for high temperature furnace applications. Alloy 330 screws unique combination of properties allow 330 hex head cap screws to handle thermal shock from quenching, be oxidation and carburization resistant as well as handle thermal cycling well.  As a result, alloy 330 hex head cap screws are found in high temperature applications like vacuum furnaces, heat treating and brazing applications.

Alloy 330 Hex Head Cap Screw Features and Benefits

It is important to differentiate between a alloy 330 hex head cap screw and hex head bolt. Often people assume they are the same, but they are actually very different fasteners in terms of how they are manufactured, as well as from an application perspective. Regardless of your choice, alloy 330 hex heads offer strong, stable joints because of their large head service.

The Hex Comparison

Hex Head Cap Screw Hex Head Bolts
  • Precise applications where tight tolerances on the body dimensions are required. 
  • Features flat washer facing under the bolt head.
  • Also called a finished hex bolt.
  • Appropriate for when mechanical properties are more important than dimensional tolerances. 
  • Hex bolts have a flat end and lack the washer face under the head.

Alloy 330 Hex Head Cap Screw Advantages  

The most important feature of a alloy 330 hex head cap screws is that it has a larger bearing surface area which provide better clamping pressure than other type of fastener such as a socket head cap screw. Additionally, since debris build up is less of an issue with this style of fastener verses a socket head cap screw, they are ideal of dirty applications where particles could clog up a socket. Though alloy 330 socket heads are typically used for tight access applications, hex heads can be a better choice when there is only side clearance available for tightening.
