#8 Silicon Bronze Frearson Oval Head wood screws appear similar to the Phillips head but the Frearson has a more pointed 75° V shape. The Frearson tool recess is a perfect cross which minimizes cam out, unlike the Phillips head, which is designed to cam out.
Traditional boatbuilders love these Silicon Bronze wood screws because they have cut threads and the full-bodied diameter shank. Unlike rolled thread screws with their reduced shank--these screws have a shank diameter that is the same size as the outside of the threads. This completely fills the clearance hole normally drilled for the shank thus creating a waterproof seal.

Silicon Bronze is the traditional choice for marine construction. It is corrosion resistant, helps prevent rot around the screw holes when used under water, and is relatively strong. Although stronger than Solid Brass, Silicon Bronze screws are not as strong as Stainless Steel. They require a carefully sized pilot hole to avoid breakage. We recommend drilling twice (once for the root and once for the shank) as well as using a fastener lubricant to avoid breakage.
MET / STD:
I have church chairs with screws falling out bronze 8 x .75 inch oval head recessed purchased from you years ago by someone else. The chairs holes are opening up. Should I go with bigger diameter same length screws and which is bigger 6 or 10?
The #10 is the larger screw, but another thought would be to go to an online woodworking supplier for good joint glue to help secure the old dry wood. Rockler or Klingspor's
#10 is bigger, maybe go to 1" long unless there is a risk of breaking through. Also make sure you have a Frearson driver bit; a regular Phillips bit will chew up the heads. PTL.
A # 10 screw is bigger than the # 6.You may try gluing a toothpick into the hole and using the same screw you have. If not use a # 10 same length.
There are 2 options.1. Put a little wood glue in the hole and then insert a couple of round wood toothpicks in the hole and break them off flush with the surface. Then reuse the same size screw.2. Go to the next larger screw (#10). Before inserting the larger screw, drill out the hole with the appropriate size tapered bit.As with all bronze screws, lubricate the screw with soap or other appropriate material to prevent breakage.Also be sure to use only Frearson screwdriver bits.Hope that this is helpful!
Probably better to remove the screws, fill the holes with something like an epoxy and redrill for the same size. Moving to a larger #10 will have a larger head so will require drilling the recess or countersink larger.
#10 is bigger and I'd use a longer screw if possible.
A #10 is larger than a #6. You should pilot for the new larger screws with a tapered drill bitt, available from Jamestown, to avoid splitting. Good Luck

I would fill these holes with-like wood and glue, than after the plugs have dried, pre drill a hole for the #8's that you already have.Thus reusing those screws. The #8 was chosen as the correct size screw, and as you stated the issue was the hole got too big, time to make the hole smaller. ( just my opinion without looking at the chairs ) # 10 is bigger than #8, ( fact )
I'm trying to replace screws that have gone missing. What is the physical description of this product in terms of inches (diameter of the screw)? I'm trying to match a 1.5 x 11/64. Or, is there a # to fractional conversion chart?Barry
Hi Barry,11/64 is equivalent to a #8 screw. For online screw size charts just google "wood screw sizes" Make sure you get a Frearson driver bit or two for these screws, Phillips bits will chew them up.Terry.
I cannot answer your specification questions but I have bought several sizes brass screws in quantity and find them to be reasonably priced, of good quality and will buy again.
Jamestown has a really handy chart that converts diameters etc to screw #'s, #10, 12, and so on. go to the home page and try entering 'wood screw size chart' or something to that effect.
Great Quality Product from JD
The screws are very strong and will not strip if using the frearson head, much better than Phillips. Great price and would recommend. I use them on gunwales for canoe and boat building and work great!

Drill twice ! I am going into black walnut and white ash. I opted for a 1/8" drill bit for the anchor hole
