Full title and description

STB DIN 80701 2017-06 — Wing nuts (German: Knebelmuttern). This designation refers to the DIN standard DIN 80701:2017-06 specifying the form, dimensions and materials for a particular type of wing (toggle) nut primarily intended for use on ships; the product is often listed in national catalogues as STB DIN 80701 2017-06 when distributed or referenced locally.

Abstract

DIN 80701:2017-06 defines one size of wing nut (internal thread M20) with a spherical bearing face, available in welded or forged design, and sets requirements for dimensions, construction and acceptable materials (including a material-grade update from earlier editions). The 2017 edition supersedes the 1991 edition.

General information

• Status: Current / active standard (2017 edition in force as replacement of the 1991 edition).
• Publication date: 2017-06-01 (June 1, 2017).
• Publisher: Deutsches Institut für Normung (DIN).
• ICS / categories: 21.060.20 (Nuts / fasteners).
• Edition / version: DIN 80701:2017-06 (revises and replaces DIN 80701:1991-05).
• Number of pages: 8 pages.

Scope

This standard specifies the execution (design), dimensions and materials for knebelmutter / wing nuts used for closing and for fixing in the open position of flaps, hatches and lids on ships. The scope of the 2017 edition is limited to a single nominal internal thread size (M20) and to nuts with a spherical support face in welded or forged form. Changes versus the 1991 edition include a materials-related adjustment (notably a change of a listed stainless grade).

Key topics and requirements

• Dimensional requirements and tolerances for the specified wing-nut geometry (one size: internal thread M20).
• Permitted designs: welded or forged construction with spherical bearing support.
• Material specifications and permitted stainless-steel grades (2017 edition updates a material entry from A2-50 to A4-70 in table(s) compared with the 1991 version).
• Intended application: fastening and locking of closures on ships (requirements chosen for marine service).
• Replacement and editorial updates: the 2017 edition replaces DIN 80701:1991 and adapts layout and rules to current DIN presentation conventions.

Typical use and users

Primary users are shipbuilders, marine-equipment manufacturers, naval architects, procurement specialists for ship outfitting, maintenance/repair engineers in the maritime sector, and fastener suppliers who must comply with DIN requirements for marine fastenings. Engineers selecting or specifying wing nuts for closures and hatches will use this standard to verify dimensions, material grade and application suitability.

Related standards

Related standards include other national and international fastener standards and stainless-steel nut property standards in the ICS 21.060.20 group (for example DIN EN ISO standards covering mechanical properties and material grades of nuts such as DIN EN ISO 3506-2 for corrosion-resistant stainless-steel fasteners and other ISO standards for nuts and prevailing-torque designs). For general classification see ICS 21.060 (Fasteners).

Q: What does it cover?

A: It covers the physical design, dimensional tolerances and materials for a wing nut with internal thread M20 and a spherical support face, intended for closing and fixing flaps, hatches and lids in ship applications.

Q: Who typically uses it?

A: Shipbuilders, marine-equipment manufacturers and suppliers, maintenance engineers in maritime operations, and fastener distributors and specifiers who need DIN-conformant parts for ship outfitting.

Q: Is it current or superseded?

A: The 2017-06 edition is the current DIN edition that replaced the earlier DIN 80701:1991-05; users should verify national adoptions or translations if they require a country-specific designation such as an STB adoption.

Q: Is it part of a series?

A: It is a stand-alone DIN product standard within the fasteners category (ICS 21.060.20) and is related by subject to other DIN/EN/ISO fastener standards that specify nut mechanical properties, material classes and related nut types (for example DIN EN ISO 3506-2 and other ISO nut standards).
