Frequently Asked Questions

What are the key specifications for this left-hand thread hex nut?
This is a metric M5-0.8 left-hand thread hex nut made from corrosion-resistant 304 Stainless Steel (Grade A2-70). It has a plain finish, a width across flats of 0.315 inches, and is designed for applications requiring reverse-threading to prevent loosening under counter-clockwise rotation.
In what applications would I typically use this left-hand thread nut?
Left-hand thread nuts are commonly used on rotating shafts or components that turn counter-clockwise under normal operation, such as certain fan assemblies, grinding wheels, or bicycle pedals. They prevent the nut from loosening due to the component's natural rotational force.
How is this product packaged for order, and what is the minimum quantity?
This nut is packaged in bulk quantities of 1000 pieces per bag or box. This industrial pack size is standard for B2B orders to support production or maintenance needs, and pricing is typically based on this unit of measure.
