Solid 651 Silicon Bronze Oval Head Machine Screws with a Slotted Drive
These machine bolts have an oval head. You can also find bronze flat head machine bolts or round head machine bolts at our store.
Our Silicon Bronze Machine Screws, often referred to as Machine Bolts, are the highest quality available, made of a solid 651 Silicon Bronze Alloy, and manufactured to meet ASME B18.6.3 standards. These fasteners are often used as bolts with nuts on the end or can be driven in to tapped holes. All of the Machine Screws we carry come with a slotted drive. These oval headed machine bolts have a countersunk head, with a standard 82 degree angle on the countersink.
4" lengths and less are fully threaded with rolled threads, while lengths over 4" are partially threaded with full body shanks and cut threads.
Silicon Bronze Strut Bolts
Also known as strut bolts, silicon bronze machine screws with an oval head are often used to attach a vessel's strut or other hardware to the hull below the waterline.
We carry one of the largest selections of solid bronze machine screws in the USA. Use them in your boat building application to attach bronze hardware, in your electrical application since bronze is such a good conductor, or in any application where the highly anti-corrosive nature combined with the beauty of bronze is fitting.
We do things a bit differently here at Fair Wind Fasteners. Rather than force you to purchase an entire box of fasteners you can put the exact quantity you need in the quantity box above and we'll box and send the perfect amount. Quantity discounts will be automatically applied.

Customer Reviews
I used these 1/4-20x2 bolts to secure the chain plates, through the hull and through some backing blocks on the inside. They worked out really well, with the washers and nuts holding all the pieces together. Nice and sturdy!
Best Bronze fastener suppler cost and fast delivery good selection
The process of ordering by phone was easy and expedient, and I received the order sooner than I expected. A good experience all around.
I needed some hard to find 3/8 x 16 x 1 1/2” silicone bronze bolts ASAP for a boat’s rudder gudgeons while the boat is hauled out. They showed N/A in stock. I sent an e-mail…crickets! So I had to buy the nearest longer size which is 3” and cut them down. Over $30 for 4 bolts. Nice bolts / lousy service.
Thanks for your order Martin. I make a point of getting back to everyone that e-mails and don't see yours here so something must have gone wrong. Apologies for any lack of communication.
We have the largest selection of bronze fasteners around and you won't find a bigger range anywhere, but even we can't carry every single size and type of fastener in bronze. We certainly try to have them all, but manufacturing and economic restraints stand in the way. I am pleased that you did find something that worked for your gudgeons and you liked the bolts as well. Hopefully we'll have exactly what you need nect time.
