DIN 465 1970-12 PDF

Full title and description

STB DIN 465:1970-12 — Slotted knurled thumb screws (adoption/reference of DIN 465:1970-12). This document specifies the form, basic dimensions and key characteristics of high knurled (thumb) screws with a straight slot intended for manual tightening and occasional tool use.

Abstract

An adoption/reference of the German DIN 465 edition published December 1970 describing knurled thumb screws with a straight slot: head geometry, nominal thread sizes and overall dimensional limits for commonly used metric sizes (typically M3–M6). The original DIN edition is short (technical drawing and table style) and focuses on interchangeability and straightforward mechanical fastening use.

General information

• Status: Withdrawn / superseded (original DIN edition withdrawn; national adoption copies also treated as historic).
• Publication date: December 1970 (1970-12).
• Publisher: Original: Deutsches Institut für Normung (DIN). National designation STB indicates a national adoption/reference of the DIN document.
• ICS / categories: Fasteners — Bolts, screws, studs (ICS 21.060, specifically 21.060.10 for screws).
• Edition / version: Edition dated 1970-12 (original DIN 465:1970-12).
• Number of pages: 2 (concise technical drawing and table).

Scope

Defines the form and principal dimensions of high knurled head screws provided with a straight slot for manual or light-tool tightening. The scope covers nominal metric thread sizes commonly used for thumb screws (examples in typical tables include M3, M4, M5, M6) and head/knurl/slot geometry to ensure interchangeability in mechanical assemblies and equipment panels. The standard is a product/shape specification rather than a materials or strength specification.

Key topics and requirements

• Head type: high knurled (thumb) head with a straight slot for occasional screwdriver use.
• Dimensional tables for nominal thread sizes (e.g., head diameter, head height, shank length ranges) to ensure mechanical interchangeability.
• General tolerances and form features for knurl and slot geometry to permit manual torque application.
• Intended fit and application notes (panel fastening, mechanical adjustments, removable covers) rather than metallurgical or heat-treatment requirements.
• References to earlier DIN editions (this 1970 edition replaced the 1963 edition) and later replacement standards in the same product family.

Typical use and users

Used by mechanical and electrical engineers, procurement specialists, maintenance teams and OEMs for equipment covers, control panels, instruments and assemblies where tool-free or hand-assisted fastening is desirable. Typical industries include machinery, instrumentation, electronics enclosures and general manufacturing. Parts suppliers and fastener distributors also reference this standard for catalogue and interchangeability purposes.

Related standards

DIN 465 (1970) follows earlier DIN editions and has been superseded in the DIN family by related fastener standards (for example documents in the DIN 464/465 family and later editions covering knurled thumb screws or equivalent product forms). National adoptions (STB) reference the DIN technical content. Users should consult successor DIN documents or national fastener standards for current, active specifications.

FAQ

Q: What is this standard?

A: STB DIN 465:1970-12 is the national designation/reference for the DIN standard edition published in December 1970 that defines slotted knurled (thumb) screws — short, drawing- and table-style specification for head form and dimensions.

Q: What does it cover?

A: It covers head form (high knurled head with a straight slot), principal dimensions for common metric thread sizes, and tolerances needed to ensure interchangeability for manual fastening applications. It is not a materials or strength standard.

Q: Who typically uses it?

A: Mechanical designers, maintenance engineers, fastener suppliers and procurement teams specifying thumb screws for equipment covers, panels and fixtures where hand-tightening or occasional screwdriver use is expected.

Q: Is it current or superseded?

A: The DIN 465:1970-12 edition is withdrawn and treated as historic; related DIN documents in the same family or newer replacement standards should be used for current procurement or design work. National STB copies that referenced this edition should be considered historic unless a more recent national update exists. Users are advised to check the latest DIN/ISO/national standards for active replacements.

Q: Is it part of a series?

A: Yes — it belongs to the family of DIN fastener/product-form standards covering knurled/thumb screws and related fastening elements; revisions and related documents (older and newer DIN editions) form the series of product-shape specifications.

Q: What are the key keywords?

A: Knurled thumb screw, slotted screw, DIN 465, STB DIN 465, thumb screw dimensions, fasteners, metric screws.
