The cage has two wings that when compressed allow the cage to be inserted into the square holes Clip-on nut: J-nut or U-nut, sheet metal nut, speed nut (ambiguously) Designed to be clipped to sheet metal Coupling nut: Extension nut A threaded fastener for joining two male threads, most commonly a threaded rod,[1][2] but also pipes Flange nut ...
Although flange fittings are bulky, they perform well in demanding applications such as large water supply networks and hydroelectric systems. Flanges are rated at 150, 300, 400, 600, 900, 1500, and 2500 psi; or 10, 15, 25, 40, 64, 100, and 150 bars of pressure. Various types of flanges are available, depending on construction.
They may either have a Phillips flat head or a slotted hex washer head. Nominal (thread) sizes range from 0.1875 to 0.375 in (4.763 to 9.525 mm) and lengths from 1.25 to 5 in (32 to 127 mm). Typically an installer uses a hammer drill to make a pilot hole for each concrete screw and a powered impact driver to drive the screw. The drill hole ...
Holes are drilled in nuts and bolt heads, and wire is threaded through the holes to prevent back-rotation. This method of locking is labor intensive, but is still used on critical joints. [1] Locknuts Some portion of the nut deforms elastically during tightening to provide a locking action. Spring washers and lock washers
A self-aligning nut, also known as a spherical nut [2] or leveling nut, is a type of nut used in applications where the fastener is not perpendicular to the surface to which the nut anchors. A flange nut is used inside a specially shaped dished-out washer. The device is commonly used in the aerospace industry.
The simplest – and strongest – form of anchor bolt is cast-in-place, with its embedded end consisting of a standard hexagonal head bolt and washer, 90-bend, or some sort of forged or welded flange (see also stud welding). The last are used in concrete-steel composite structures as shear connectors. [6]
Some bolt heads instead lock the bolt in place, so that it does not move and a tool is only needed for the nut end. Common bolt heads include hex, slotted hex washer, and socket cap. The first bolts had square heads, formed by forging. These are still found, although much more common today is the hexagonal head.
A split beam nut, also known as a split hex nut [1] or slotted beam nut, [2] is a locknut with slots cut in the top that separate the outside end into two [3] or more sections that are bent slightly inward, making the thread diameter undersized in the slotted portion.
