What is BS EN 4399 - Threaded rings about?
BS EN 4399 is a European standard on aerospace series which covers rings, threaded, self-locking, in heat resisting steel FE-PA92HT (A286), silver plated.
BS EN 4399 specifies the characteristics of threaded, self-locking rings, in FE-PA2601, silver plated, metric, chiefly used for axial location of bearing outer rings.
Note: These parts are designed to be used with 4H6H internal threads.
Who is BS EN 4399 - Threaded rings for?
BS EN 4399 on threaded rings is useful for:
- Manufacturers of aerospace equipment and components
- Threaded rings manufacturers
Why should you use BS EN 4399 - Threaded rings?
Thread ring gauges are designed to be used for go/no go gaging. Thread ring gages are used for inspecting external screw threads of manufactured parts. With go/no go thread ring gauges, an inspector can quickly pass or fail parts without taking time consuming readings from a measuring instrument.
Heat resistant steels are solid solution strengthened alloy steels for use at temperatures above 500 deg C and upto 750 deg C. As these steels are used over a certain broad temperature ranges, they are normally strengthened by the hardening mechanism of heat treatment, solid solution, and precipitation.
When it comes to the manufacturing and use of aerospace components, reliability and consistent performance are crucial. Hence BS EN 4399 walks you through the characteristics of threaded, self-locking rings, in FE-PA2601, silver plated, metric, chiefly used for axial location of bearing outer rings. This ensures safety and reliability in your organization and in turn increases the efficiency of work.
