Overview

This left-hand thread hex nut is engineered for industrial fastening applications where standard right-hand rotation could cause unintended loosening. Manufactured from grade 304 stainless steel, it provides excellent corrosion resistance for use in demanding environments. The nut conforms to the DIN 934 standard for dimensional consistency and features a coarse thread pitch for robust engagement. Its reverse threading is a critical design element for assemblies subject to counter-clockwise forces, ensuring a secure and reliable connection.

Key Features

Left-hand (reverse) thread direction to secure against counter-clockwise rotation Constructed from corrosion-resistant AISI 304 stainless steel Meets material strength grade A2-70 for reliable performance Conforms to DIN 934 dimensional specifications for interchangeability Coarse thread pitch for strong holding power and easier assembly Plain, non-plated finish suitable for a wide range of conditions

Frequently Asked Questions

What are the key specifications for this left-hand thread nut, and how does the A2-70 grade affect performance?
This is a metric M3 left-hand (reverse) thread hex nut made from 304 Stainless Steel with a plain finish. The A2-70 grade indicates a tensile strength of approximately 70,000 PSI, providing excellent corrosion resistance and good mechanical strength for general use.
In what applications would I typically use a left-hand thread M3 nut like this?
Left-hand thread nuts are used in specific applications where rotation could cause a standard right-hand thread to loosen, such as on the left side of bicycles, certain rotating machinery shafts, or assemblies where opposing forces are present. They are commonly paired with left-hand thread bolts or screws.
How are these nuts packaged for order, and what is the width across the flats for wrenching?
These nuts are packaged in bulk quantities of 1000 pieces per bag or box. The hex width across the flats is 0.236 inches (approximately 6mm), which is the standard size for an M3 nut and compatible with a 6mm wrench.
