What are heavy hex nutsHeavy hex nuts are somewhat larger than a standard hex nut, compatible with high strength and large diameter bolts. Their additional strength comes from increased thread engagement, which is due to their thickness, and greater resistance to dilation (expansion or stretching) b

A coupling nut, also known as extension nut, is a threaded fastener for joining two male threads, most commonly a threaded rod, but also pipes. The outside of the fastener is usually a hex so a wrench can hold it. Variations include reducing coupling nuts, for joining two different size threads; sig

Chipboard screw is a kind of product which is suitable for the installation of electric tools. It is mainly used for the connection and fastening between wood plate, wood plate and thin plate. To a large extent, it can replace the use of common wood screws (wood screws are not heat-treated).At the same time, the wooden screw is now first put forward by the beacon process, not only saves the material, but also the thread is sharper.

What are rivet nuts? A rivet nut, also known as a blind rivet nut or threaded insert, is a one-piece internally threaded and counterbored tubular rivet that can be anchored entirely from one side. There are two types: one is designed to form a bulge on the back side of the panel as a screw is tightened in its threads. The other is similarly drawn in using a screw, but is drawn into the sleeve instead of creating a bulge.

The spring nut is now used more and more, and it is more convenient to use the spring nut on many mechanical equipment.When using the spring nut, pay attention to the tightening, and the load should not exceed the stress of the spring nut, so as to avoid damage, and because it is a spring, it is necessary to pay attention to the problem of crevice corrosion.

Nuts are hexagonal metal heads usually threaded over long, rod-shaped bolts. When mated with, or connected to, a bolt, a nut provides strong fastening and holding power. Nuts and bolts are used in almost every trade imaginable, from home construction and bicycle manufacturing to car production and shipbuilding. Though a variety of different types of nuts exist, including slotted, square, nylon locking and acorn nuts, most all are tightened and adjusted in the same way.
