Review on 🔩 GRK 8x4 Inch 100 Piece: High-Performance Screws for Efficient Projects by Ben Demers

05/08/21 Edited Comment: Yes they are great but $16 for $100 is overpriced! Cost $7.50 in 2018. Original Review: These are great screws but I would caution you that they are difficult to drill to match the surface. The head is small, with small incisors on the underside, allowing the head to easily dig into the surface to sink itself. But it doesn't stop there! Even with a very low clutch position on my drill, the heads dug into the hardwood-faced plywood. In all other respects they are great.
