Full title and description

ISO 10597:2012 — Road vehicles — Flat attachment fixing nuts for commercial vehicles — Test methods. This International Standard specifies test procedures and performance criteria for hexagonal wheel nuts with a flat seating captive washer used on commercial vehicles.

Abstract

This standard defines the test methods and performance requirements to ensure correct wheel or rim assembly when using hexagon nuts with a flat-seat captive washer for 18 mm, 20 mm and 22 mm studs. It is applicable to commercial vehicles as defined in ISO 3833 and to the relevant nut dimensions specified in ISO 7575; it excludes fasteners intended for less common or special applications.

Scope

Specifies test methods and performance requirements for flat-attachment (flat-seat) hexagon nuts with captive washers used as wheel fixing nuts on commercial road vehicles. The scope covers nuts intended for 18 mm, 20 mm and 22 mm studs and is intended to ensure safe and secure wheel assembly on vehicles covered by ISO 3833; it does not cover specialised or uncommon fastener applications.

Key topics and requirements

• Defined test procedures to verify mechanical and assembly performance of flat-seat captive-washer wheel nuts.
• Performance criteria for secure wheel/rim assembly under expected service conditions.
• Dimensional and application linkage to ISO 7575 (essential nut dimensions for 18 mm, 20 mm and 22 mm studs).
• Applicability to commercial vehicles as defined by ISO 3833 (vehicle type/definitions).
• Exclusion of special-purpose or atypical fasteners from the standard’s requirements.

Typical use and users

Used by vehicle manufacturers, wheel and fastener component suppliers, testing and certification laboratories, aftermarket wheel suppliers, quality and compliance engineers, and regulatory bodies concerned with vehicle wheel assembly safety. It is applied during component design verification, incoming inspection, type testing and conformity-to-type activities.
