nice quality
We used these to connect cabinets at the face. They worked out great and hold good. pre-drill hardwood with a 1/8" drill bit and they were nice and tight with no chance of splitting. After using hundreds, the start heads are perfect, no stripping. The heads are nice and small to hide, can barely be seen.

These fasteners were exactly what I needed to secure 2x6 boards with toenailed screws and not leave a head showing, since I could countersink them all just a bit, and I will cover them with putty to keep the wood watersealed. They have great bite as they go in, and do a nice job of securing these boards. This is a redo of a screened porch before placing new SCREEN TIGHT system (also from HD) on the inside of the porch, and on the face of these boards and the existing trim. New boards are at the base, and I will be adding 2x4's with same screws to mid point. Old external wooden screens in the photo can be removed after I install the new system.

Bought these to re-attach Azek Decking that I had to pull up because of support board failure (after 10 years, wet (ish)) to replace the wood underneath. These have a self-drilling tip and screw down well. (You need to pay attention to NOT pull all the way through this material. (see pictures)
These go in on a diagonal, through the side of the decking leaving only a small hole that is not very visible. These were just what I wanted for the job (very similar to what the contractor had used when the deck was built).
I have used GRK fasteners for a number of projects and these "odd" configuration fasteners are much nicer than "normal" screws.

GRK FIN/Trim Head Screws are an excellent choice for most fine carpentry applications. The FIN/Trim is also suitable for the installation of window extension jambs and molding. Special features include W-cut threads and Zip tips to help prevent wood splitting. The screws are Climate coated for corrosion resistance.
GRK's R4 Self Countersinking screw has 6 self-contained cutting pockets which act like a router and transport the drill dust away from the edge of the screw hole. They also widen the countersink hole only around the head shape. The screw head top closes the hole exactly, leaving no damaged fibers around the wider area of the head. The R4 head design is so effective that it will not crack even the most brittle materials.
