Aerotight Plain Steel Locknut, RoHS Compliant, Metric Thread, Size M4, Width 7mm, Overall Height 4.79mm A2AEROTIGHTM04RS

The Aerotight brand A2AEROTIGHTM04RS model is a high-quality plain steel locknut designed with metric threading and sized at M4, featuring a width of 7 mm and an overall height of 4.79 mm. It complies with RoHS standards, ensuring environmentally safe manufacturing.

This locknut is constructed entirely from A1 grade type 303 stainless steel, providing excellent material strength and allowing use at temperatures up to 300°C. Its all-metal design makes it particularly suited for applications subject to severe vibration as the cantilevered threaded arms create a self-locking mechanism that stays in position whether tightened or not.

The Aerotight stiff nuts are reusable and designed to maintain reliable fastening over multiple uses without degradation in locking performance. The product is ideally used in industrial contexts such as mechanical assemblies, fluid power systems, construction fasteners, and machinery maintenance where secure fastening with resistance to vibration loosening is critical.

For optimal use, it is recommended that two complete threads of the engaged screw protrude beyond the nut to ensure the locking arms function correctly. The locknut should not be used on damaged or interrupted threads to maintain locking integrity.

Steel material with plain finish for durability. Metric thread and M4 size providing compatibility with standard screws and bolts. Self-locking with cantilevered threaded arms resisting vibration loosening. Reusable and suitable for use in high-temperature environments up to 300°C.
