03Technical description

The 304 A2 Stainless Steel UNF Hex Nut is an industrial nut for machinery, equipment exposed to moisture, maintenance and moderate-precision assemblies. It is made from 304 A2 stainless steel and works with UNF thread; where applicable, the reference is related to UNF thread. Its main difference is 304 A2 stainless steel with fine inch pitch for UNF fasteners. 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

  • Verify diameter, pitch and thread series before installation.
  • Use the correct wrench size to avoid rounding the flats.
  • Where vibration is present, add a washer, threadlocker or lock nut according to the design.
  • Do not mix classes or grades without validating bolt compatibility.

04Frequently asked questions

What is the price of the 304 a2 stainless steel unf hex 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 304 A2 stainless steel UNC hex nut?

UNF is fine pitch and UNC is coarse pitch. Both may be 304 A2, but they are not interchangeable.

How is the 304 a2 stainless steel unf hex 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.
