Full title and description
St SAE MA3379A-2020 — STUD, STRAIGHT — 2.5 DIA ENGAGEMENT, A286 MJ METRIC 6 X 1 - 6 X 1. This SAE technical standard (MA3379A, Revision A, 2020) specifies the characteristics and procurement requirements for straight studs manufactured from A286 (nickel‑iron‑chromium) alloy with the indicated metric MJ thread and engagement geometry.
Abstract
MA3379A:2020 provides a short, product‑level specification for a straight stud design used in aerospace applications: nominal 2.5 diameter engagement, material A286, MJ metric thread series 6 × 1 (both ends). The document gives dimensional definition, material designation, basic mechanical/heat‑treatment and identification/marking requirements appropriate for procurement and production control.

Scope
This standard defines the dimensional, material and basic procurement/identification requirements for a straight stud with 2.5 diameter engagement made from A286 alloy and specified MJ metric thread size 6 × 1 (6 × 1 — 6 × 1). It is intended for use where a short, repeatable stud specification is required for aerospace assemblies (including propulsion/engine applications) and to replace/supersede earlier MA3379 editions.
Key topics and requirements
- Designation and dimensional drawings for a straight stud with 2.5 diameter engagement and MJ metric thread (6 × 1).
- Material specification: A286 (nickel‑iron‑chromium alloy) and associated heat‑treatment/strength expectations for the application.
- Basic mechanical/acceptance requirements, identification/marking and procurement notes for manufacture and inspection.
- Reference/cross‑references to related aerospace and material specifications used in procurement (AMS/AS references commonly supplied alongside SAE fastener standards).
Typical use and users
Used by aerospace design and propulsion engineers, procurement/specification writers, fastener manufacturers and quality/inspection personnel. Typical applications include engine and propulsion component assemblies where a short, high‑integrity stud of A286 material and specified metric thread engagement is required. Users rely on the standard for repeatable procurement, interchangeability and inspection criteria.
