GOST 14737-69 PDF

Full title and description

ГОСТ 14737-69 — Шпонки призматические привертные. Конструкция (English title: Screw fixed sunk keys. Construction). The standard specifies constructional forms, principal dimensions and application of prismatic screw-fixed (sunk) keys used for fastening fixtures and attachments on machine tool tables.

Abstract

This intergovernmental (GOST) standard, originally approved in 1969 and put into effect from 1 July 1970, establishes the design and basic requirements for prismatic screw-fixed sunk keys intended for positioning and clamping devices on machine-tool tables. It includes dimensional series, basic tolerances, material and heat‑treatment guidance and references to related normative documents and amendments.

Scope

The standard applies to prismatic screw-fixed sunk keys designed for installation of fixtures and attachments on machine‑tool tables. It covers the constructive shapes, size series, tolerances and basic technical requirements necessary to ensure interchangeability and proper functioning when used in machine‑tool assemblies. It does not replace specific technical conditions for specialized non-standard parts unless referenced.

Key topics and requirements

• Definitions and constructive types of prismatic screw-fixed (sunk) keys.
• Dimensional series and nominal sizes (standardized length, width, thickness and interface geometry).
• Tolerances for form and mating dimensions to ensure interchangeability.
• Material grade recommendations and references to steel standards for manufacturing.
• Requirements for marking, storage and basic inspection (visual and dimensional checks).
• References to normative documents and incorporated amendments (amendments integrated into text in reprints).

Typical use and users

Typical users include machine tool designers, fixture manufacturers, metalworking shops, procurement specialists and quality engineers responsible for ensuring component interchangeability and proper fixturing on machine tables. The standard is used when specifying or producing prismatic keys for clamping fixtures, jigs and tooling assemblies in manufacturing environments.

Related standards

Normative references and related documents cited with this standard include predecessor MN 4790-63 (replaced), and various material and dimensional standards such as ГОСТ 4543-71, ГОСТ 1050-88, ГОСТ 24643-81, ГОСТ 12876-67 and corrosion/finish references like ГОСТ 9.306-85. The text also notes Amendments published in IUS issues (9-80, 11-86, 7-89).

FAQ

Q: What is this standard?

A: ГОСТ 14737-69 is a Soviet/Interstate (GOST) standard that defines the construction, dimensional series and basic requirements for prismatic screw-fixed (sunk) keys used to mount and position fixtures on machine‑tool tables.

Q: What does it cover?

A: It covers constructive types, nominal sizes, tolerances, material recommendations and references to related normative documents; amendments have been issued and integrated in later reprints. It is not a detailed specification for every special application but provides the standard basis for interchangeability.

Q: Who typically uses it?

A: Designers of machine-tool fixtures, manufacturers of keys and fastening elements, procurement engineers and quality control personnel in metalworking and tooling industries.

Q: Is it current or superseded?

A: Multiple authoritative listings mark ГОСТ 14737-69 as действующий (in force). The restriction on its period of validity was lifted (reference to a 1989 decision), and the document has had reprints integrating amendments; however users should verify whether a more recent national/regional replacement or an industry-specific technical specification applies to their project.

Q: Is it part of a series?

A: It is part of the family of GOST standards related to machine-tool accessories and fastening elements; it references and sits alongside material/steel standards and other fastening‑element standards rather than forming a numbered continuous series. It replaces MN 4790-63 and is linked by normative references to other GOSTs.

Q: What are the key keywords?

A: Prismatic keys, screw-fixed (sunk) keys, shponki, fixture keys, machine‑tool table fastening, dimensions, tolerances, ГОСТ 14737-69.
