## Questions & Answers

**Q: What is the load strength on these?  1500lbs?**
A: Not sure but would depend mostly on the strength of the metal you put it into.

**Q: Do you need a special tool for this or can you just screw a bolt in and go?**
A: Can't screw the bolt in and go. You're supposed to have a special tool but my husband devised his own.

**Q: How will I know when to stop tightening these into my base material? I'm installing with a ratchet wrench, is there a torque I can set my wrench to?**
A: There's no actual torque setting, but typically when setting the insert,  and being that the insert is pre-bulbed, once the insert is tight you will feel a noticeable increase in turning pressure - signifying the insert is tight.

**Q: Does this come with the small setting tool**
A: No. I didn’t receive a tool. I used a bigger size nut and washer to set on top and screwed bolt into shank to set them.

*by D***. on 26 November 2025*

Was using standard rivnuts, and they worked well, but I wanted something with more surface area. I tried these and they worked great. I have more confidence in the amount of surface area these use. Will certinly reach for these over the other version when possible.
