Assembly tools for screws and nuts - Single-head engineer's wrenches for lower torque applications - Maximum outside dimensions of heads and test torques

ISO 13778:2017 specifies requirements of single-head engineer's wrenches with nominal width across flats from 3,2 to 120.It specifies the maximum outside dimensions of heads and gives the test torque values. The "lower torque application" designation is in accordance with the smaller head dimensions.NOTE The wrenches covered by this document are the ones identified in ISO 1703:2005 under reference Nos. 1 1 01 01 0 and 1 1 01 01 1.

Assembly tools for screws and nuts - Single-head engineer's wrenches for lower torque applications - Maximum outside dimensions of heads and test torques

ISO 4229:2009 specifies characteristics of single-head engineer's wrenches with gaps from 7 mm to 120 mm, listed in ISO 1703 under the reference Nos. 1 1 01 01 0 and 1 1 01 01 1. The “lower torque application” designation is in accordance with the smaller head dimensions. Essentially, ISO 4229:2009 establishes the first specifying maximum outside dimensions of heads and gives the test torque values, which are calculated on the basis of approximately half the values, in accordance with ISO 1711-1, series C.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
