DIN 8141-2 1993-07 PDF

Full title and description

ISO‑metric screw threads; coarse pitch threads and fine pitch threads for interference fits in aluminium cast alloys; nominal diameter from 5 mm to 16 mm; gauges for internal and external threads. This document (DIN 8141‑2:1993‑07) specifies the design and dimensions of gauges used to check internal and external threads intended for interference fits in aluminium casting alloys for nominal diameters M5 to M16.

Abstract

DIN 8141‑2:1993‑07 defines the gauges (internal and external) used to verify ISO‑metric coarse and fine pitch threads intended for interference (press) fits in aluminium cast alloys with nominal diameters from 5 mm to 16 mm. The standard complements DIN 8141‑1, which contains nominal sizes, tolerances and limits of sizes. It is a short, focused document primarily presenting gauge dimensions and acceptance criteria for thread inspection.

Scope

The standard covers gauges for checking internal and external ISO‑metric screw threads (coarse and fine pitches) that are intended to create an interference fit when assembled into aluminium casting alloys. It applies to nominal thread diameters from 5 mm up to 16 mm and gives the required gauge dimensions and acceptance characteristics for use in production and quality control. DIN 8141‑2 is intended to be used together with DIN 8141‑1, which defines the nominal sizes, tolerances and limits of size for those threads.

Key topics and requirements

• Definition of internal and external thread gauges appropriate for interference (press) fits in aluminium casting alloys.
• Applicable nominal diameters: M5 through M16 and both coarse and fine pitches for those diameters.
• Dimensional specifications for gauges (limits and nominal dimensions) used to confirm thread form and size.
• Reference to the associated tolerances and limits of size provided in DIN 8141‑1.
• Intended use in quality control and verification of thread production for aluminium castings to ensure correct interference fit and assembly performance.

Typical use and users

Manufacturers of aluminium cast components with threaded features, fastener and thread‑gauge producers, tooling and inspection labs, automotive and aerospace component suppliers, and quality/engineering departments use this standard to select or design gauges and to verify thread production for interference fits. It is also used by metrology labs that supply inspection services for threaded castings.

Related standards

DIN 8141‑2 is part of the DIN 8141 series and is directly linked to DIN 8141‑1 (Nominal sizes, tolerances and limits of size). It sits alongside other DIN and ISO documents covering metric screw threads, thread tolerancing and gauges. Users commonly cross‑reference ISO/DIN thread standards and DIN handbook materials for engineering threads.

FAQ

Q: What is this standard?

A: DIN 8141‑2:1993‑07 is a DIN standard that specifies gauges for inspecting ISO‑metric coarse and fine pitch screw threads intended for interference fits in aluminium casting alloys for nominal diameters from 5 mm to 16 mm.

Q: What does it cover?

A: It covers the dimensional and gauge requirements (internal and external gauges) used to verify that threads produced in aluminium cast alloys will achieve the intended interference fit; it complements DIN 8141‑1, which defines nominal sizes, tolerances and limits of size.

Q: Who typically uses it?

A: Engineers, production and quality personnel in foundries and component manufacturers that produce threaded aluminium castings, gauge manufacturers, metrology/inspection laboratories, and OEMs in automotive, aerospace and machinery sectors.

Q: Is it current or superseded?

A: The 1993‑07 edition of DIN 8141‑2 is listed in standards catalogues as the valid edition; commercial standards providers and DIN catalogues list the 1993 version as the current edition. Users should verify with the official DIN catalogue or their national standards body for any amendments or newer editions before relying on it for regulatory or safety‑critical work.

Q: Is it part of a series?

A: Yes — DIN 8141‑2 is part of the DIN 8141 series and is intended to be used together with DIN 8141‑1 (which specifies nominal sizes, tolerances and limits). Other related DIN/ISO thread standards and DIN handbooks on threads are commonly used together with this part.

Q: What are the key keywords?

A: ISO‑metric thread, interference fit, aluminium cast alloys, thread gauge, internal gauge, external gauge, M5–M16, DIN 8141, metric screw threads.
