Blvdre Posted January 30, 2009 Share Posted January 30, 2009 I posted this over at Lansing/Heritage, but figured I might get some help here as well: I have a pair of 2470's in need of rear cap screws. It's an 8/32 x 1.5"screw, but the catch is, it has a tiny head (in order to fit into therecess). I tried calling JBL parts, but they no longer carry thisoddball screw. I checked McMaster Carr until my eyes were bloodshot,but couldn't find what I was looking for (that doesn't mean it's notthere though, their amount of screw stock is overwhelming). I evenbought some hex head equivalents, but the head's a bit too big (notsure how successful grinding down the heads would be, doesn't soundlike fun). Any suggestions?

Blvdre Posted January 30, 2009 Author Share Posted January 30, 2009 Thanks, yes, I checked those out (online, I mean). Didn't think it was what I was looking for, as the head looks a bit to wide in their pic, but Widget seemed to think those are them. I already put an order in, so we'll see when they arrive. In the meantime, I'm going to try and grind down the hex heads a bit to see if they'll do. It's certainly easier to get a hex driver down that hole, compared to a #2 philips.

The dimensions are used to determine if the screw fits the application prior to ordering. Quote Link to comment Share on other sites More sharing options...
Blvdre Posted January 31, 2009 Author Share Posted January 31, 2009 Yes, I did see the head dimension, but didn't check the hole before ordering, as I didn't have my rear cap with me at work (we have running orders for McMaster, so I just put it in). I looked at .270 on my mic, and it looked a bit big to my eye. We'll see how it pans out (a bad pun for a different screw...). Quote Link to comment Share on other sites More sharing options...

pocket.change Posted February 1, 2009 Share Posted February 1, 2009 Allen screws and washers worked for me after frittering away a bunch of time searching for something that simply isn't available any longer. Quote Link to comment Share on other sites More sharing options...
capo72 Posted February 1, 2009 Share Posted February 1, 2009 I ended up making my own. I just spun down the heads on a lathe at work, and colored them black with a Sharpie. Worked well for me. Jeremy Quote Link to comment Share on other sites More sharing options...
Blvdre Posted February 1, 2009 Author Share Posted February 1, 2009 I thought about using a longer screw w/washer, but I'm a stickler for proper appearance. It I decide to sell the drivers down the road, it will help if they look correct. So I set up my dremel with a grinding wheel, and secured it in my vise. Then I wrapped the hex screw threads with tape, and gently tightened it in my hand drill chuck. Fired up the dremel and the drill, and ground the hex head wall down a bit. Worked like a charm. One down, seven to go. Quote Link to comment Share on other sites More sharing options...
