SUMMARY

The recommended wrench clearance according to TEMA Table D5 is not explicitly defined for wrench clearance determination, as the table primarily focuses on minimum dimensions for bolt spacing designs using a standard box end wrench. For comprehensive guidelines on wrench clearances for various wrench styles, the "Machinery Handbook" published by Industrial Press is the authoritative reference. This handbook is essential for Mechanical Engineers in the US and provides critical insights into wrench clearance specifications.

PREREQUISITES
  • Understanding of TEMA (Tubular Exchanger Manufacturers Association) standards
  • Familiarity with mechanical engineering principles
  • Knowledge of standard box end wrench dimensions
  • Access to the "Machinery Handbook" for reference
NEXT STEPS
  • Review TEMA Table D5 for bolt spacing dimensions
  • Study the "Machinery Handbook" for detailed wrench clearance guidelines
  • Explore mechanical design principles related to tool clearance
  • Investigate industry standards for mechanical engineering practices
USEFUL FOR

Mechanical engineers, designers, and students seeking to understand wrench clearance requirements and best practices in mechanical design will benefit from this discussion.

I am trying to obtain minimum recommended wrench and nut clearances from TEMA Table D5, but I don't really know what quantity from this table I should be using.

That table is directed more at minimum dimensions for bolts spacing designs with a standard box end wrench rather than for wrench clearance determination. A good general reference for wrench clearances for all styles of standard wrenches is the "Machinery Handbook" published by the Industrial Press, if you can locate one. This book is a basic reference requirement in the US for any Mechanical Engineer.

thanks, I found the handbook. I just want to make sure if C is the wrench clearance.
