### ⭐⭐⭐⭐⭐ 







  
  
    Excellent Quality replacement Hobby Grade Screws at a great price
  

*by C***G on Reviewed in the United States on April 13, 2020*

I bought this set for extra and replacement screws for my SAB Goblin 700 RC Helicopter.  The original screws either started to rust or strip, and when I looked for the manufacturer replacement screws, they cost was outrageous for only several replacement screws.  This set is only a decent quality or at least of equal quality of the original, it contains a wide assortment of lengths with plenty of each size.  It's almost criminal that such an affordable alternative which will make absolutely no difference in the build exists.So glad I found this set.

Needed an unusual length for radiator + fans + halos + case connection, the selection in this product was the only one that provided assurance that I'd have the necessary screw...and they have hex heads! The best choice for quality, quantity and perfect fit.

*by D***K on Reviewed in the United States on September 21, 2017*

Decent assortment of Allen head bolts that fit your standard PC water cooling radiator.  If you have extra thick fans or if you need to pass through something to mount your fans to your radiator or your radiator to something else, then these are a decent kit.
