Why do we chamfer nuts?

Chamfering eases assembly, e.g. the insertion of bolts into holes, or nuts. Chamfering also removes sharp edges which reduces significantly the possibility of cuts, and injuries, to people handling the metal piece.

What is the use of hexagonal nut?

The use of a hexagonal shape makes fasteners easier to turn by reducing the required turning distance. To tighten a bolt or nut, you must turn it. Thanks to their side sides, hexagonal bolts and nuts require a turning radius of just 30 degrees to reach the next flat parallel.

What is the radius of chamfer are for square nut?

Square nut: Dimensions of a square nut: If D = the nominal diameter of the bolt, Thickness of the nut, T = D Page 4 4 Width across flats, W = 1.5D + 3mm Angle of chamfer = 30° Radius of chamfer arc, R = 2D (approx.).

What is meant by hexagonal nut?

Definitions of hex nut. a nut with a hexagonal shape. type of: nut. a small (usually square or hexagonal) metal block with internal screw thread to be fitted onto a bolt.

Which type of nut is used for hand tightening?

A knurled head thumb nut or thumb nut has a knurled outside surface rather than a hex, which facilitates tightening by hand. Often used in decorative finishes or applications.

How are chamfers machined?

Chamfers are typically made with a tool that’s ground to the correct angle, such as a spot drill, countersink, or chamfer tool. Due to a straight angle, chamfers can be cut with a single machine pass using tools like this countersink. Fillets are typically created with an end mill that machines the part profile.

What is the height of hexagonal nut where D is nominal diameter of bolt *?

The height of the standard hexagonal nut is 0.8 d. The threads of the bolt in the standard nut will not fail by shear. So, the height of the nut is the most important design dimension.

What is the height of hexagonal nut?

In case of square nut the spanner can have better hold but the angle is 90 degrees so it is more convenient to use hexagonal nut. 3. Width across the flats in case of hexagonal nut is___ where D is the diameter of the shank.

What is a hexagonal nut made out of?

Hexagonal nuts are generally made from steel that has been specially cut with the help of a steel cutting machine. The entire process is relatively quick, and thousands of nuts can be produced within a matter of minutes.

What is the name of the nut which is a hexagonal nut with a washer?

Flanged nut
What is the name of the nut which is a hexagonal nut with a washer? Explanation: Flanged nut is hexagonal nut with a washer that is a flat circular disc attached to it. It is thus provided with a larger bearing surface. A bolt can be used in a comparatively large-size hole with help of this nut.
