Specification

 

      ANSI/ASME b18.2.2 Hex Nylon Insert Lock Nut by available Material and Size

     

      Nylon insert lock nut (also called non-metallic insert lock nuts or nyloc nuts) manufacturers have historically used the strength designation of Grade A, B and C, established by the Industrial Fastener Institutes standard IFI-100/107, to designate the three different strength levels that these nuts can be manufactured to. End users typically order lock nuts using the more common industry standard strength levels (also called the SAE strength levels) of Grade 2, 5 and 8. In 2008 the US standards organization ANSI published a new nylon insert lock nut standard and introduced another grade designations for this style of lock nut: NE2, NE5 and NE8.

 

       Each of these “grades” are designed to be used on the following strength level of bolts, studs or cap screws: Bolt Strength Level Lock Nut Strength Level Grade 2 Grade A, 2 or NE2 Grade 5 Grade B, 5 or NE5 Grade 8 Grade C, 8 or NE8

Product application

 

        ANSI/ASME b18.2.2 Hex Nylon Insert Lock Nut are in the group Nuts. Nuts, or mating fasteners, are available in hundreds of different shapes and sizes for any project or application. Varieties are normally hexagonal or square in shape, and have either coarse or fine internal threads that correspond to those of a mating bolt or screw.

.

 

     Lock nuts are available in numerous styles, grades and finishes. The term “lock nut” is not meant to imply that there is an indefinite permanency of fixity once used. Most locknuts can be removed and some can even be reused if removed correctly. Lock nuts are most commonly available in ASTM A563 Grades A and DH and ASTM A194 Grade 2H. They are manufactured with a standard hex or a heavy hex pattern. Two of the most common lock nut styles are Anco and Tri-Lok. The Anco style is a self-locking nut with a ratchet pin that is made from stainless steel. This ratchet pin slides along the threads as the nut is spun onto the bolt and prevents the nut from backing off. One benefit to using an Anco style lock nut is that the ratchet pin can be bent back so that the nut can be easily removed if needed. The Tri-Lok style is a “prevailing-torque” locknut which is frictionally resistant to rotation due to the thread distortion on the top thread of the nut. For various other types of lock nuts, please call one of our estimators!

Since hot-dip galvanizing typically adds 2.2 to 5 mils of thickness to the threaded portion of a fastener, galvanized lock nuts are tapped oversized to compensate for the corrosion resistant coating on the bolts.
