What’s the hex nut?

The nut is a part of the fastener. It works with the stud and threaded rod. The bolt or rod must be the same size as the nut and have the same thread. Different nut standards work in different industries. 

The main standards are DIN, ISO, JIS, ASTM / ANSI. The nut project is suitable for different fastener projects. The surface finish of the nut should be smooth, black, galvanized, hot-dip galvanized. 

Hexagonal nut 

A Hexagonal nut Also known as finished hex nuts, DIN 934 hex nuts fixed to install with DIN 933 or DIN 931 hex bolts, these hex bolts are used together for the heavier patterned version of the heavy hex nut standard hex nut for automotive industry construction projects, ASTM B18.2.2

heavy hex nut

ASTM A563 heavy hex nuts, ASTM A194 Gr-8M heavy nuts, are connected with hex heavy bolts, used in various industrial machinery manufacturers. 

Nylon Insert Lock nuts 

nylon inserts to prevent backlash. Also called nylon lock nut. DIN 985 nylon insert lock nuts work in long-term vibration projects, mainly for single installation and anti-loosening, and cannot be reused.

Prevailing torque lock nut

980v dominant torque. Common shapes are as follows: three-point, oval Type, side extrusion type. It is widely used in aviation, mining machinery, automobile transportation machinery, agricultural machinery, textile machinery, electrical products, etc. 

Universal Torque Lock Nut 980m Universal Torque Lock Nut is embedded in a thin metal plate after heat treatment, and the metal inner diameter piece is slightly smaller than the outer diameter of the bolt thread. After tightening the nut, the metal piece locks the bolt thread, which can effectively prevent loosening and anti-vibration. 

Hexagon nuts using guide

Hexagon nuts are one of the most common nuts and can be used with anchors, bolts, screws, studs, threaded rods, and any other fasteners with machine threads. Hex is an abbreviation for hexagon, meaning that they have six sides. Hex nuts are also called: finished hexagon nuts and full hexagon nuts. 

Hexagon nut lock washers can use hex nuts UNC and UNF threads. Hexagon nut threads are standard unified and British coarse (UNC, national unified coarse) or British unified fine (UNF, unified national fine) series. Left hex nuts are also available; see the nut on the left. The size of a hex nut refers to its nominal thread diameter. Hex nut installation tools usually range in size from 1/4”to approximately 2 1/2”. 

Dimensions are in inches and are usually decimals rather than decimals. Table 1 lists the width and thickness between faces and corners. The width of the wrench size is 1.50-1.75 times the nominal size of the hexagonal nut, and the thickness is 0.850-0.875 times the size. Nuts 5/8” and smaller nuts have double chamfers (top and bottom); larger sizes may be double chamfered or have washers. 

Support surface (bottom) and chamfered top nuts, bolts/screws must be long enough , So that at least two full threads extend beyond the surface of the nut after tightening. On the contrary, two full threads should be exposed on the side of the nut head to ensure that the nut can be tightened correctly. Unlike stainless steel and stainless steel, like brass Similarly, steel hexagon nuts have different degrees of strength; specified by SAE (Society of Automotive Engineers).
