03Technical description

The 304 A2 Stainless Steel UNC Lock Nut is an industrial nut for washable equipment, moderate outdoor exposure, supports, guards and industrial maintenance. It is made from 304 A2 stainless steel and works with UNC thread; where applicable, the reference is related to UNC thread. Its main difference is that it combines a nylon insert with 304 A2 stainless steel for inch-thread joints exposed to moisture. To buy without errors, the critical data is not only the diameter: the pitch, thread series and grade or material of the bolt, stud or threaded rod must also match. TECTUL offers it per unit and organizes selection by actual catalog sizes for maintenance, replacement and production purchases.

Installation recommendations

  • Do not reuse the nut if the nylon insert has lost threading resistance.
  • Avoid applying direct heat to the nylon insert during installation or rework.
  • Use a washer when the base material is soft or has slots.
  • Apply the torque defined by the drawing for the bolt-nut assembly.

04Frequently asked questions

What is the price of the 304 a2 stainless steel unc lock nut?

The price depends on size, finish and quantity. TECTUL quotes this reference per unit and can validate availability before dispatch.

How is it different from the zinc plated UNC lock nut?

304 A2 stainless steel is prioritized for corrosion; zinc plated is an economical option for protected environments.

How is the 304 a2 stainless steel unc lock nut installed?

Clean the thread, confirm diameter and pitch, start threading by hand and tighten with the proper tool according to the torque defined for the assembly.

How do I choose the correct size?

Take the nominal diameter and pitch of the male thread. In inch threads, distinguish UNC from UNF; in metric, confirm the pitch indicated in millimeters.

Is it suitable for outdoor use?

It depends on the material and coating. Stainless steel and hot-dip galvanized finishes better resist exposure; zinc plated, black or black oxide finishes are recommended for protected environments.

Is it sold per unit or by package?

The lot is configured per unit. For maintenance or production consumption, TECTUL can quote quantities by size.
