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.
Quickly delivered and excellent quality. I still want #3 and #4 wood screws
Excellent fastenings shipped out quickly! Customer for life
Good product. Very prompt delivery
The silicon machine bolts, washers, and nuts I ordered worked perfectly for my 1957 boat restoration project and will last far beyond my ownereship. Thanks!
Fair Wind has a great selection of fasteners. I needed some short bronze screws for a sailboat project and they had exactly what I needed.
