Review on Enhanced Durability: Bronze Coated Exterior Screws for Heavy-duty Projects by Mark Clark

If you look at the photo of one of the screws I made you will see that the bit tip advertised in the listing is actually just a small notch that has been machined, and that's not even at the top of the screw. A tapping drill 1/2" above the bolt body is useless, a Hillman fastener with a bit on the tip got it right. I definitely think the value for money at £5 for less than $40 is pretty good is good but this is just a case where it seems like you get what you pay for.Poor craftsmanship is one of the greatest sins because it is a physical manifestation.Don't do what you want to others that they do to you.
