Questions and Answers for GRK Fasteners #8 x 2-1/2 in. White Star Drive Low-Profile Washer-Head Wood Cabinet Screw (80-Pack)

A:  Major diameter is 0.1640 for a #8 screw.

A:  5/32's of an inch

A:  for my detailed projects I ALWAYS pre-drill the placement of screws! and I may be a bit over the top with it as I do it on a drill press !! a lot of my "hobby" work is for game pieces and boxes to hold them in. time is of no plan in my building I take my time and do it s l o w so I only have to do it once ...

A:  I predrill the mounting board at the top of cabinet to make sure the cabinet is drawn tight to the wall. An alternative is using screws that have smooth shanks on the top inch that would not require drilling.

A:  You should yes

A:  Yes, I found pre drilling necessary after trying one without it. Depending on the material the screrws have a sort of drill tip, but different than a self drilling screw. Going into particle board type stuff the screw wouldn't dig in. I think I used a 3/32 or similar small bit to just make a pilot hole so the tip of the screw wouldn't walk or slip off. I was putting them in from underneath pushing up. Trying to keep the screw and bit lined up is where the predrilling was a good idea.

A:  The beauty of the new generation "engineered" fasteners like GRK and Spax is that they are self drilling/self tapping. The cone headed general construction screws from both are also self countersinking. Now that doesn't mean that if you have a 1x2 face frame that the screws put in near the ends won't split the wood. I'd be safe and pre-drill the fasteners within a few inches of the board ends Anything away from the ends doesn't need pre drilling. These are pretty much a point and go fastener. The old style screws required pre drilling, and then you'd drive the fastener in about a third, back it out, drive on another third, back out, then drive it home. I've watched very experienced boat builders with air tools be able to do that with a very fluid motion over and over all day without camming out or stripping a screw. I'd rather pay the extra 2 to 4 cents per fastener for these new fasteners that make me look good.

A:  I believe it is a fine thread - about 12 per inch. See the photo showing a comparison of the GRK 8 x 1" cabinet screw and a Coarse Thread #6 x 1-1/2" drywall screw (9 threads per inch).

A:  These are coarse threaded, self-tapping, hardened, star drive wood working screws. Fine threads are for metal. GRK fasteners are one of the new generation of engineered fasteners that generally eliminate the need for pre-drilling. These are the Washer Head screws that stop at the surface of the wood with a large decorative flat washer head. Their regular construction screws are self countersinking. They also have a slim-head line of fasteners where the head sinks below the surface, leaving a relatively small hole. I've had cam out problems with the slim-head fasteners...about one or two in every project cams out and has to be removed by twisting it slowly out backwards with a pliers or surgery with a rotary tool. The time savings with these no pre-drill, no countersink, very positive drive fasteners makes them well worth the extra price over the old-style philips or square drive fasteners. I keep a collection of various sizes and don't feel guilt anymore for the extra cost. They are well worth it.

A:  they are wood screws. 90% of wood screws are course thread. as are 95% of fine thread screws are for metal or compound materials such as plastic. also the packages are clear so all a person has to do is look close at the content !

A:  We loved these. So easy to use and the box with its drill bit was perfect. We will definitely be using this brand again.

A:  The box I bought came with the driver.

A:  Driver? Framing hammer

A:  T-15

A:  I believe a bit is included in the box, but the screws take a Torx/star size 20 bit.

A:  Depending on the size of the screw, the star drive head size is listed on the package, a free bit is included in each box. Small screws use a T-15, larger ones a T-25.

A:  They are Great hold very well and star drive means no slippage while installing them, large head works great for holding up shelving brackets

A:  Yes

A:  no

A:  These are for hanging cabinets and the others are structural screws. In my shop I used these to hang pegboard.

A:  No they are a different screw. Climatec is a coating on the screw. Screw your referring to is for structural work, decks ; framing.

A:  The head will protrude and not be as smooth as nails.

A:  The answer is simple. Yes, you could but why would you? The range of nails for sheathing is wide and the normal 8d coated sinker is completely adequate unless you have some unusual situations. A hammer or nail gun makes short work of smaller projects and I don't see any advantage to using a screw instead of nails. Just my opinion but you do what ever you like!

A:  No Issue is the heads would be elevated on top of the decking. Screw Head will not countersink into the surface of the roof decking.. Grip-Rite Coarse Threads is what you need.

A:  No.

A:  I would not use them on roof sheeting. The head sticks up to far and will eventually wear through the shingle. Just use a hammer stapler works better and is faster.

A:  I cannot answer that question. I did not use them on any metal. What I do know is The threads are not fine and the tip is not designed for cutting through metal.

A:  No, these are made to be installed in wood. You need to use a sheet metal screw if using metal studs.

A:  Yes on low torque with your drill.

A:  NOT a good idea !!!!! the type of groves in the thread are for wood, metal needs a much smaller and tighter thread to hold in place !

A:  According to the specifications these will work in metal. They are also self tapping, no predrilling.

A:  Any washer head screw with a diameter of .360 or less will work with both the Milescraft and the Kreg pocket hole jigs.

A:  Yes, these will work in that jig.

A:  I don't see why not

A:  They should work just fine.

A:  In brick , concrete screws, in wood, course 1 1/2” #2 Phillip’s head

A:  If you are installing new construction windows you can use regular roofing nails.

A:  Should be. They have an all weather coating on them. The head on them is 7/16" for a good hold. You might want to contact GRK with that question for warranty coverage on your windows.

A:  If you are concerned about exterior use of this product based on label I would suggest using a similar product with usage label suitable for your application. Direct contact with moisture, moist materials, and outdoor elements may degrade fasteners relatively quickly. Is the quality and durability of your project going to be compromised based on your fastener choice? If so, get the proper products. If not, save a buck or two and make it work.

A:  On the box itself there is nothing about interior use only.

A:  They are cabinet screws and are no good for exterior use. They will rust outdoors.
