Benefits of Screw Down Nut Blanks 

A screw down nut is a fastener that attaches to a bolt, screw, or stud to provide clamping force and prevent axial movement. They typically have threaded connections, but sometimes it’s beneficial to receive them blank, or without threads. 

Blanked screw down nuts are semi-finished components. They’ve undergone all necessary processing, such as heat treatment and machining, except for threading. This allows cutting of threads without having to perform other manufacturing steps, saving time and money.

Let’s Get Started 

As a leading industrial screw down nut manufacturer, U.S. Bronze Foundry & Machine strives to forge long-term relationships with customers. Our experts work with you to cast the best parts possible. 

Client-Tailored Screw Down Nut Blank Solutions

For industrial processing and heavy machinery applications, standard screw down nuts aren’t always best. Factors like equipment age, construction, and location may require parts manufactured to custom sizes.

U.S. Bronze Foundry & Machine specializes in the development and production of custom screw down nut castings. We leverage advanced metalworking equipment, highly skilled labor, and expert engineering to make blanks small enough to fit in the palm of a hand or bulky enough to fit on train beds. 

Versatile Fastening Solutions 

Nuts are an integral part of heavy machinery. These components strengthen whatever they’re holding together, which improves longevity and performance. Screw down nut blanks from U.S. Bronze Foundry & Machine are perfect for use in many applications. 

A stringent quality management system ensures every casted component meets applicable industry standards or client specifications. We can produce rough parts as quickly as two weeks and finished pieces as fast as eight weeks, depending on lead time and other factors.
