AI Technical Summary

Technical Problem

Threaded fasteners experience significant torsional stresses when driven into substrates like concrete, leading to shearing failures and shank breakage due to frictional resistance, necessitating a solution to enhance shank strength and reduce failure likelihood.

Method used

A threaded fastener design with a shank comprising multiple portions and helical thread formations, including grooved sections to optimize material distribution, resulting in a stronger shank with larger diameters and reduced torsional forces.

Benefits of technology

The design enhances the torsional strength of the shank, significantly reducing the likelihood of failure and improving the fastener's overall durability.
