Solid 651 Silicon Bronze Machine Screws in Flat Head, Oval Head, or Round Head with a Slotted Drive

All of our silicon bronze machine screws come with a SLOTTED DRIVE.

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, but you can choose either a flat, oval, or round head in the box above. The flat and 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.

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.

Excellent customer service, great quality, fast shipping, good packaging.


The order arrived seemingly immediately after I ordered it, and the screws are just as the website promoted them! Great!!

I needed a number of small bronze hardware items to repair and restore the hardware on a 1971 Handy Cat 14’ gaff-rigged catboat. I needed about twenty #10-32 nuts. I inadvertently forgot to include the nuts in my online order. So, when the order arrived there were no nuts!

However, all other items ordered arrived when stated, and all items were were sent. Faiwinds met all my expectations. The bolts, screws and washers were all high quality and ideal for my restoration work. I was able to complete my repairs to the Handy Car and look forward sailing the “fair winds and following seas of Cape Cod.

PS The nuts will be sent in a separate order, along with cotter pins I also overlooked.

fast, fair, fine quality

Every order from FWF, no matter how small or big, arrives quickly and correctly.
couldn’t ask for anything more!
