What is a 12 point nut?

What is a 12 point nut?

This 12 point design allows more torque to be applied to the joint. 12 point nuts are used with 12 point flange bolt or screws. These 12 point nuts are manufactured in high tensile material grades but can be produced across all material categories and astm specifications.

What do nut numbers mean?

The number has nothing to do with the size, but does indicate the relative strength of the bolt. The higher the number, the stronger the bolt. Some metric nuts are also marked with a single-digit number to indicate the strength, and some may have the M and strength grade embossed on the flats of the hex.

How do you read a standard nut size?

If the nut is metric, count the number of lines on the tape measure to find the measurement. If you count 9 lines, the size is a 9-mm (millimeter) nut. If the nut is US standard, count the smallest lines on the tape measure in sixteenths. Add the sixteenths together to find the size.

How big are the 12 point flange nuts?

Steel High-Torque 12-Point Flange Nuts Flange Flange Thread Size Wd. Ht. Dia. Thick. 1/4 “-20 5/16 ” 19/64 ” 7/16 ” 0.06″ 1/4 “-28 5/16 ” 19/64 ” 7/16 ” 0.06″

Why are 12 point nuts better than hex nuts?

With more points of contact than a hex, these flange nuts allow you to get a better grip for more driver torque. The flange distributes pressure where the nut meets the material surface, eliminating the need for a separate washer. They have a black-oxide finish for mild corrosion resistance in dry environments.

What are the dimensions of Grade 2 nuts?

Grade-2 nuts are for use with any low carbon bolt or screw that is not heat-treated, with a specified minimum tensile strength of 74,000 psi or less. A six-sided internally threaded fastener whose thickness is .875 where D is the nominal nut size and 1.5D is their width across the flats.

How does a 12 point nut work in a washer?

The flange distributes pressure where the nut meets the material surface, eliminating the need for a separate washer. They have a black-oxide finish for mild corrosion resistance in dry environments. Height includes the flange. For technical drawings and 3-D models, click on a part number.
