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.
