## Questions & Answers

**Q: Would these do well on galvanized pipes that are round vs square?**
A: Yes - these will actually work extremely well with square pipe.  With round pipe the flange may not seat correctly being that the head of the insert is flat.

**Q: Who makes a mandrel for this? Drill/Impact and bolt not working in particular application.**
A: Is the mandrel too short to set the insert?  We recommend a mandrel length of at least 1.75" long. We do sell this size, but not on Amazon.

**Q: What size drill bit is suitable for installing these? I'll be increasing the size of various existing holes in my Sprinter van to fit these. Thanks**
A: The recommended work hole diameter is .390 - so a 25/64 drill bit will work.

**Q: Is there a 1/4-20 that is shorter than 1"?  (Don't have enough clearance on back, but need the strength of 1/4")?**
A: For Multi-Grip inserts - No - the shortest available length available is 1".  However a Thin-Nut Steel Threaded insert's length is .680 (actual grip range is .165-.260) - here's a link: https://www.amazon.com/s?k=skl2520260&ref=nb_sb_noss
