The screw, also known as an auger, is the heart of any screw conveyor or screw feeder. It is the essential component that defines the performance, capacity, and reliability of the entire conveying system. While many screws conform to standard or stock configurations, lengths, and materials of construction, demanding applications often require heavily modified or fully custom screw designs to withstand harsh operating conditions.

In many cases, replacement screws are upgraded to improve long-term durability and performance. For example, a stock carbon steel screw may be replaced with abrasion-resistant flighting to combat excessive wear, or the screw length may be modified to eliminate hanger bearings and improve structural stability. For feeder screws, mixing screws, and other specialized applications, the original conveyor may have been engineered with a custom screw from the start. In these situations, maintaining proper function requires a replacement screw built to match the original design specifications.

Screw conveyor screws are available in a wide range of diameters, pitches, lengths, and configurations. At SCP, we stock the most common screw sizes and configurations to support routine maintenance and quick replacements. However, many applications require custom screws to meet unique process demands, system upgrades, or challenging material characteristics. SCP offers industry-leading capability to design and supply custom screws quickly and competitively—often within one to two weeks.

Getting started is simple. Email us, complete the custom screw form or screw worksheet with the information you have available, and our team will assist in filling in any missing details. If you are unsure of your existing specifications, you can also send us your screw for a complete evaluation, repair, and/or rebuild. Our goal is to restore or enhance your conveyor’s performance with a screw that meets your exact operational requirements.

Common Custom Screw Features
