What Customers Are Saying

Customers overwhelmingly praise these T-nuts for reliable performance and solid build quality, with most highlighting their ability to securely anchor bolts in wood without splitting and noting smooth threading and easy installation across diverse applications. The three-prong design receives consistent commendation for biting firmly and preventing loosening over time. Many appreciate the variety of lengths available and clean metal construction. However, several customers voice concerns about pricing, describing the cost as excessive compared to alternatives elsewhere. A few report prongs bending during installation in dense wood or receiving damaged units, though these issues represent a small minority. Overall, reviewers strongly recommend the product despite cost reservations.

Not what I expected

Would Not Recommend

Bought these to add feet to a shelving unit I made. Not sure what I was doing wrong, but these were not great at holding the feet in. May work better on a hard wood, but on soft wood, they just couldn't get enough bite to hold on so as soon as we turned the shelf over, the feet came off... with the nut attached.

Nut for only low tension uses.

Would Not Recommend

The teeth dig into the door wood just marginally. Attaching a pull knob and using it to open door it falls out.
