ASTM F3148

ASTM F3148 — Grade 144 structural assemblies

Fixed-spline assemblies: identify the bolt, nut, washer arrangement and installation requirements together.

Send your specification

A complete assembly, not a generic bolt

Identify the entire system: bolt, nut, washers, dimensions, finish, equipment and installation procedure. Components with the same diameter are not automatically interchangeable.

Data required for supply

Technical fieldRequirement
Rm min.144 ksi
ConfigurationFixed-spline
DimensionsDiameter, length and grip range of the selected system
InstallationInstructions and checks for the specific assembly

Do not infer equivalence between standards from tensile strength in ksi alone. Check the standard and proposed system for temperature, exposure and outdoor-use limitations.

Keep F3148 and F3125 distinct

The appearance of 144 ksi in the current F3125 title does not make the specifications interchangeable. Always state the full designation, edition and required system.

Configuration and installation

Provide type, dimensions, specified installation method or equipment, and required tests. Installation instructions or torque values are not derived from the grade alone.
