What is BS EN 3729 – Threaded rings about ?
BS EN 3729 is a European standard on aerospace series which covers rings, threaded, self-locking, left-hand thread, in heat resisting steel FE-PA92HT (A286), silver plated.
BS EN 3729 specifies the characteristics of threaded, self-locking rings, with left-hand threads, in FE-PA92HT, silver plated, 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 3729 – Threaded rings for ?
BS EN 3729 on threaded rings is useful for:
- Manufacturers of aerospace equipment and components
- Threaded rings manufacturers
Why should you use BS EN 3729 – 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.
Much like their cousins, thread plugs, thread rings are machined Go/No-go gages that contain internal threading, machined to a very specific thread size. They are used for checking externally threaded components (i.e. bolts).
When it comes to the manufacturing and use of aerospace components, reliability and consistent performance are crucial. Hence BS EN 3729 walks you through the characteristics of threaded, self-locking rings, with left-hand threads, in FE-PA92HT, silver plated, 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.
