Solid 651 Silicon Bronze Flat Head Countersunk Machine Screws with a Slotted Drive

These machine bolts have a flat, countersunk (CSK) head. You can also find bronze oval 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 flat headed machine bolts have a countersunk (CSK) 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.

Small Lots of Bronze Fastners

I have a 24 foot sailboat with a fiberglass hull and a wooden deck and cuddy. The boat has bronze winches and other bronze fittings. In adding some deck hardware I wanted to use bronze fastners. I have ordered four or five small lots of eight bolts, washers and nuts or fewer from Fair Wind Fastners and have been extremely pleased with how Fair Wind has rapidly and courteously fulfilled my small orders, even the one time when I had to call and make a change due to my error. It is too bad the Fair Wind bronze nuts, bolts, and washers have to disappear into the bronze hardware, because they are beautifully made in addition to being of high quality. Good people to deal with.
