Wayne, Today I was looking for a replacement bolt for the one's that hold the main spar to frame 'C' in my coupe. They are MS20004-8 socket headed cap screws. While researching for a substitute or equal I looked into a data base at work and found that MS20004 has been superseded by NASM200004 (National Aerospace Standard). Both of these only tell you for example what a MS200004-8 is dimensionally, in this case a 1/4 x 28 UNJF-3A that is 1.5" long. The procurement spec for both is MIL-B-7838. This spec has all of the meat such as material origin, heat treatment, strength, tolerances, testing, thread dimensions, etc, etc. Rich Blair N99997 4J6 St. Marys, Georgia ==^================================================================ This email was sent to: [EMAIL PROTECTED] EASY UNSUBSCRIBE click here: http://topica.com/u/?aVxiLm.aVzvvT Or send an email to: [EMAIL PROTECTED] T O P I C A -- Register now to manage your mail! http://www.topica.com/partner/tag02/register ==^================================================================
