Product Description
Carriage Bolt with Nuts and Washers
Carriage bolts have a dome shaped head and a square neck generally requiring a hex nut and flat washer. The square neck makes them self-locking when used within a square hole.
The smooth, domed head provides a semi-flush finish.
Drill a hole in the surface material that matches the diameter of the fastener, insert the bolt, and connect the nut on the other end.
Hex Bolt with Nuts and Washers (Flat +Lock)
Hex Bolt is one kind of threaded fasteners with a hexagonal head shape, and normally designed to be installed using a spanner. Hex bolts are favoured for their robust shape, which makes them suitable for more heavy-duty fastening applications.
Hex bolts are also generally available in larger sizes than alternative fasteners.
Hex Bolts are also called hexagon bolts.
Button Socket Cap Screws with Nuts and Washers
The clean and bright button head make it ideal uses in furnitures, 3D printer projects and other indoor or outdoor projects.
Flanged Hex Bolt with Nuts and Washers
The extra large washer head helps to distribute the load. The one-piece design eliminates the need of a separate washer and can be more efficient and easier to use. A washer is still needed on the nut side so the set we provide help you save your time and money.
