ASME B1.5-1997 Acme Screw Threads

Standard Number:  ASME B1.5-1997
Title:  Acme Screw Threads
Language:  English
Status:  Current
Publisher:  American Society of Mechanical Engineers (ASME)
Price:  
Number of Pages:128  

Description:Describes two general applications of Acme threads- namely, general purpose and centralizing. The limits and tolerances in this Standard relate to single-start Acme threads and may be used, if considered suitable, for multiple-start Acme threads.
