## Questions & Answers

**Q: anybody been able to self tap into hard 1/4" steel sheet?**
A: I used them to tap into a 1/4 in. angle iron brick lintel. It sometimes required a second screw to get through the metal.

**Q: With regard to the product buildex 1075000 1/4-28 x 4 tek 5 screws hex self-drilling climaseal (50 pack), is there any way to buy a smaller count?**
A: I found none at the time I purchased.

**Q: #12-24x3/4 zink coated\   do you have this screw   ?**
A: Yes, we do, but it is not listed on Amazon yet. If you would like to purchase it, please contact us, and we can create the link for it later today.

**Q: I need to attach 3/4 plywood to 1/8 angle iron are the threads long enough for that?**
A: I'm 95% sure these are the screws I tried to use to screw into 1/8" thick hot dipped galvi tube. Even pre-drilling, the stainless couldn't get through. Also, I think the drill part was long enough that the threads won't get through the wood and into the steel.
