A little sloppy fit with the 1 inch # 10 screws but filing the tip helped. Fit the 1 3/4 screws well.
Quality precision tool,
The bit held up to driving multiple fasteners. Great bit.
I recently purchased some #6 and #8 bronze flat head wood screws and Frearson driver bits. The quality of the screws is excellent. The threads are really well formed and the Frearson head is perfect. The bits fit the screws like a glove. Good products and prompt delivery. Thanks.
Extremely fast shipping and excellent communication. Highly recommended
