Self-tapping Screws

16 ft x 100 ft gothic tunnel

I think every upgrade they made is well worth the price my tunnel had caved it from a weird snow storm wind event I got my replacement tunnel in a very timely matter this is a great company I will be ordering from them agin

Great product

I've used self tappers previously that doesn't have near the drilling capacity these screws have.
