I need to make a quote on some nut and sleeve fittings to customer urgently and still have some questions on the drawing, need help immediately. Thanks a lot! Q1: What do the 2 hook like marks on the DRAWING 1 mean? Q2: Does CSK on DRAWING 1 means countersink? Q3: What does PD and MD on DRAWING 1, do they mean PD=PICH DIAMETER, MD=MEAN DIAMETER? Q4: "surface marked 100 must be 100 micorinches RMS max.what does RMS mean? Q5: EDGE MUST BE SHARP on DRAWING 2: does it mean the edge no radius?

The "Two Hooks" mark is the customer's company logo to be stamped on the nut.

Hi Randy and Kelly, thanks a lot for your professional answers. I will ask the HOOKS from customer and if they give me an explain, I'll post it on here for reference.

1. I DON'T KNOW about hooks.. ................... OK Gals and guys, let's hear a qualified answer about the "hooks". ................... 2. yes countersink at 90° 3. PD = pitch diameter, MD = minor diameter 4. 100 RMS is the surface roughness, about half between 125 and 63 standards in root-mean-square. 5. edge must be sharp, not de-burred. Usually is a cutting edge. 6. FIM = full indicator movement, similar to TIR or total indicator reading, relates to a full rotation of the part against an indicator The worst suggestion of your lifetime may be the catalyst to the grandest idea of the century, never let suggestions go unsaid nor fail to listen to them.

This drawing is a classic "Drawn to Personnal Drafting Standards" drawing, instead of industry standards. FIM = Full Indicator Movement. The Concentricity can mean any number of things, however I suspect they realy mean Total Runnout. Total Runnout is when you locate a reference cylindrical feature in a device allowing rotation and place a dial indicator on another coaxial cylindrical surface and rotate. The FIM is the maximimum displacment reading obtained from the dial indicator. The hooks look like a CAD printing problenm or translation. I would call and ask for the responsible engineer or designer and ask very politely what every thing means. Just tell them that you realy want to do a good job and are double checking with them to be sure you understand. Modified by Kelly Bramble at Sun, Feb 25, 2007, 16:03:15
