Frequently Asked Questions

What are the key specifications and material properties of this coupling nut?
This is a DIN6334 standard coupling nut made from 304 Stainless Steel with an A2-70 material grade, offering good corrosion resistance and a tensile strength of approximately 70,000 PSI. It has an M4 thread size, is 3.94 inches long, with a 0.236 inch width across flats, and features a plain (uncoated) finish.
What is a typical application for a right-left hand (reverse thread) coupling nut like this?
This nut is designed to join two threaded rods or studs with opposite thread directions (one right-hand, one left-hand). A common use case is in turnbuckle or tensioning assemblies, where rotating the nut simultaneously draws the two ends together or pushes them apart to adjust tension or length.
How is this item packaged and what is the minimum order quantity?
This coupling nut is packaged in quantities of 100 pieces per bag or box. The listed price and fulfillment are typically for this standard pack size of 100 units.
