#8 Stainless steel flat head phillips wood screws. Wood screws have coarse and deep threads to better anchor into wood. Flat head screws are used for general fastening when the screw head will be flush with the surface or when it will be countersunk and the hole will be plugged. Phillips drive allows for greater torque application when fastening. Stainless steel provides strong corrosion resistance.
These marine grade screws provide excellent corrosion resistance and are the work horse for modern boatbuilding or exterior woodworking applications.

MET / STD:
do you carry screw kits ie #6 ss wood screws 1/2, 3/4, 1/2, 2'' etc?
No. If it were fully threaded, it would not pull the two materials together. There is enough unthreaded portion to pull in about 1/4" of material, such as 1/4" plywood to a 3/4" stringer. Never buy fully threaded screws except for drywalling!
No, as in the picture, there's a shank between the head and the start of the threads

How many screws per box?
They are usaully 100 pre box
Most of the boxes I bought were 100 or 50
How long of a screw is necessary for screwing two 5/4 (full inch) boards together?
Jim, The usual recommendation is to have the screw penetrate into the supporting structure 1.5 times the thickness of the supported piece. However, in your case, this is not possible since they are both 1". I would use a 1 3/4" wood screw of the largest reasonable size with proper countersink and pilot hole. This will give you as much penetration as possible without coming through the other side. If it is a critical application with a lot of load you might consider through-bolting.Steve
Depends on whether you are countersinking the screws and using adhesive between the boards. If you are doing both, go with an inch and a quarter. If you are doing neither, add another half inch.
If you are going to countersink the screw flush and not plug the hole then either 1 1/2 or 1 3/4 should work. If you are going to plug the hole, be sure to use a good countersink, set the stop or mark the countersink to cut 1/4" depth and use 1 1/4 or 1 1/2 screws.hope this helps
which screw has a smaller diameter shaft? 8 or 18?
Screws are sized with the diameter number smaller to larger so 8 is smaller than 18. A number 14 happens to be 1/4" diameter
The larger the screw size the larger the diameter. #10 is larger than #8, etc. I am not familiar with #18, however, since that would be pretty large.Steve
How do I change the screw size and length?

I used to work in a boatshop in the 80's. The most common screw by far was the 1.25" X #8 SS FH phillips wood screw. We used them for everything and almost every "cleat" that was used for interior woodwork. My question is what is the standard for today's boatshop? Is this style screw still the gold standard for boat construction or are people chosing square or some other drive style and if so why?
Chuck,Short answer is yes, it's my "go to" size for a lot of fastening needs anywhere near water.Gnawbone Jack
Hi Chuck I use square drive all the time due to ease of use and the fact that the screw rarely strips. That being said, I have spoken to boat builders who swear by Phillips head. Hope that helps
Chuck,I have been working in a yard for some time now, and these are still the best all around fasteners. There is always a box of these in the tool kit.Steve
What type of stainless are thes screws 302, 034 or 316 ?
Flat Head Phillips Drive18-8 stainless steel Marine grade 300 series stainless steel. 18-8 Stainless is the workhorse for modern boat building.
On screw boxes( for wood) the size is specified like this - 30x7. What does it mean?
I'm not sure if the current boxes of screws I have now are from 2009 or not. Anyway there is no marking on them that says 30X7. Printed markings are for the grade of Stainless 18-8 and then the gauge number and length #8 3/4". Maybe its a metric measurement, wish I could be more helpful.Bill B.
I won't be able to use the out of the cabin for fear they will rust . They are great general purpose screws not marine quality.

Don't expect a full inch
Don't expect full holding power with these screws. They are closer to 7/8" than one inch.I suppose who you save 1/8" a million times that the savings adds up for somebody. Just don't expect to be the one saving.

Stainless steel screws
I ordered several different sizes of these screws. To me, they work better than the Bronze screws. I'm building a small paddle boat for the kids & myself. The Stainless Steel do not rust and strong when it comes to bow construction where you are bending plywood. Great product!!
