Half Hex Open End

Half Hex Open End

Not sure how to install a nutsert?

One step-by-step guide covers every nutsert size, with CAD diagrams for each step.

Installing with a nutsert tool

Hole size, grip range and stroke setting - the guide shows how to get a solid, reusable thread first time, plus the no-tool method for one-off jobs.

Under-set, correctly set and over-set nutsert cross-sections

Hex flats on part of the body key into a hex hole; the round lower section drops in more easily than a full hex.

WHY A RIVET NUT, NOT A WELD NUT OR TEE NUT

A rivet nut sets a captive thread into thin sheet, tube or panel from one side - no welding, no tapping and no access to the back of the work. A weld nut needs welding gear and clean bare metal; a tee nut needs a timber panel to bite into; a standard hex nut needs you to hold a spanner on the back. The rivet nut is the captive-nut answer when the material is too thin to tap and the back face is sealed or unreachable.

BEST FIT

Choose half hex as the middle ground - more spin resistance than a round body, simpler to set than a full hex.

SIZES AND MATERIALS

16 variants in G304 stainless and zinc plated, M3 to M10.
