Specifications For

Stainless Steel Hex Bolts Nuts Studs

 

 

Comments:

  • What are fastener standards?
  • Fastener Standards address the dimensions, testing, and use of screws, bolts, nuts, rivets, and studs.

 

  • What does ASTM stand for with bolts?
  • ASTM – The American Society for Testing and Materials(ASTM) – Mainly For Fasteners used in Petroleum, Oil & Gas industries.

 

  • What does ASME B18.2.1 mean?
  • ASME B18. 2.1 is the standard specification covering the dimensional requirements for nine product types of inch series bolts and screws recognized as American National Standard

 

  • How do I choose bolts for the flange?
  • The number of bolts for a flange connection will be given by the number of bolt Holes in a flange, the diameter and length of bolts are dependent on flange type and Pressure Class of flange. Stud Bolt lengths are defined in ASME B16. 5 standards.

 

  • Is ASTM the same as SAE?
  • ASTM (American Society for Testing and Materials) covers primarily bolts and fasteners for construction applications.
  • SAE (Society of Automotive Engineers) covers fasteners for automotive, machinery, and OEM applications.

 

 

  • Which are ASTM Studs Bolts standards?
