03Technical description

stainless 304-A2 UNC full thread hex bolt is a hex head bolt for inch assemblies exposed to humidity, washing or moderately corrosive environments where full thread is required. At TECTUL it is quoted per unit and by actual available size, cross-checking diameter, length, pitch, material, finish and standard before confirming price. This reference is differentiated by 304-A2 stainless steel, UNC thread and a fully threaded shank; it is not metric DIN 933. The material reported for the lot is 304-A2 stainless steel. For class 8.8, 10.9 and SAE grades, selection must respect the requested mechanical property; for DIN 933, DIN 931, DIN 960 or DIN 961, full, partial, standard or fine thread geometry is validated according to the drawing. For ASTM A325, A490 or A394, the project standard defines bolt, nut, washer and assembly. We do not publish single torque or load values because they depend on lubrication, coating, grip length, thread condition and engineering criteria.

Installation recommendations

  • Avoid contaminating stainless steel with carbon steel; use a compatible nut and consider suitable lubrication to reduce galling.
  • Clean threads, holes and bearing surfaces before assembly to avoid false tightening.
  • Do not mix metric thread with UNC or UNF; if in doubt, compare against a sample, drawing or thread gauge.
  • Apply the torque or tightening method defined by engineering, considering lubrication and coating condition.
  • Check grip length and remaining thread so the joint clamps on the parts, not on the thread end.

04Frequently asked questions

What is the price of stainless 304 A2 UNC full thread hex bolt long?

The price depends on size, length, quantity, finish, standard and availability. TECTUL quotes per unit with the exact reference requested.

How does it differ from stainless A2 DIN 933 full thread hex bolt?

Both are 304-A2 stainless and full thread, but this one uses UNC inch thread and DIN 933 uses metric thread. They do not share the same nut.

How is this hex bolt installed or assembled?

It is installed by verifying diameter, pitch, usable length, compatible nut and assembly torque according to the equipment or drawing. Do not force a thread that does not start freely.

What information should I send for a quote?

Send diameter, length, pitch or thread, quantity, material, finish, required standard and a photo or drawing if you are replacing an existing reference.

Does it include a nut or washer?

The sale is handled per bolt unit unless the quotation specifies a set. Indicate whether you need a nut, flat washer, lock washer or structural set.

Does TECTUL dispatch to other cities?

Yes. TECTUL dispatches to Bogotá, Medellín, Cali, Barranquilla and other cities in Colombia depending on availability and carrier.
