Joshua Anderson Posted January 25, 2014 Report Share Posted January 25, 2014 Hi all, I left set yesterday without measuring the nuts and bolts that secure the mounting block on the bottom of my ALP 620 Antennas. Some have fallen out and I was hoping to go to the hardware store today to look for replacements. I'm hoping someone here might know the size off hand. Thanks!

ben lowry Posted January 25, 2014 Report Share Posted January 25, 2014 Hi Josh, My ALPs (500, 620, 650) are tapped with holes for pretty much any mounting bolt you might have on set in the US: 1/4"-20, 3/8" (boom pole), and 5/8" (mic stand). I think all the Lectro ALPs I've encountered have all of these options. Ben Lowry Quote Link to comment Share on other sites More sharing options...
Joshua Anderson Posted January 25, 2014 Author Report Share Posted January 25, 2014 Hi Ben, Sorry for the confusion. I'm looking for the bolts that attach the mounting block to the antenna itself. They are made to unscrew, so you can reposition the mounting block for different ways to orient the antenna. But some of mine have fallen off from use. Thanks, Josh Quote Link to comment Share on other sites More sharing options...
ben lowry Posted January 26, 2014 Report Share Posted January 26, 2014 Gotcha. Looks like a 6-32 screw with a 5/8" long shaft. Ben Lowry Quote Link to comment Share on other sites More sharing options...
Joshua Anderson Posted January 26, 2014 Author Report Share Posted January 26, 2014 Thanks Ben! I think you're right. Greg Sextro PM'd me yesterday and we tried figuring it out at the hardware store, settling on 6-32 bolts as well. Trying them tomorrow. Out of the 12 screws on my 3 shark fins, I might need to use almost all of the 10 pack I bought. I'm not really sure how the antennas are still holding together, but I'm glad I happened to look up at them the other day. Josh Quote Link to comment Share on other sites More sharing options...
BAB414 Posted September 2, 2014 Report Share Posted September 2, 2014 I'm doing a little custom project for someone using the ALP 620. Are these screws pictured below the ones you're saying are 6-32? I'm in desperate need of nuts for the ones in the picture and Home Depot can't give me any info on them. Sadly, I know nothing about screw dimensions or nomenclature. Any help would be great. Thanks!

BAB414 Posted September 2, 2014 Report Share Posted September 2, 2014 You're right. I posted this hoping to get an answer before they opened up today (I'm east coast). Will get in touch with them. Quote Link to comment Share on other sites More sharing options...
unmguy2000 Posted September 2, 2014 Report Share Posted September 2, 2014 It's a #6-32 x 5/8" stainless steel pan head phillips machine screw. The mating nut used is a #6-32 keepnut (integrated lockwasher). It can be fastened with a nut and separate lockwasher as well. Home Depot should have this as it is a fairly common size.

John Blankenship Posted September 2, 2014 Report Share Posted September 2, 2014 For things like these nuts and bolts, a local hardware store is often much more helpful than a big box chain -- especially, if you don't know exactly what you need.

BAB414 Posted September 2, 2014 Report Share Posted September 2, 2014 I would have thought so, but when I was looking for a nut for some BDS stuff all the mom and pop shops told me to try home depot. No one had it, and neither did HD. Quote Link to comment Share on other sites More sharing options...

Josh Hi Josh, Did they work loose on their own? I'm curious if the integrated lock washer is not "good" enough. They need to be removable if you want to change the orientation but they shouldn't remove themselves.

No one had it, and neither did HD. If we lived in the same city I would bet you lunch that I could walk into a local hardware store and find the nuts and bolts needed in your photo above-- in stainless steel even. I'm a frequent visitor of the nut & bolt isles of both major chains and well-stocked mom and pops for all manner and variety of fabrications. Unless it's for a unique specialty item, I'll bet you can find a better stocked local alternative. Quote Link to comment Share on other sites More sharing options...
Joshua Anderson Posted September 6, 2014 Author Report Share Posted September 6, 2014 Sorry to respond so late - been on a TV show with night shoots, and my wife gave birth to our first kid six weeks ago. So, I haven't been as up to date on the forum or sleep lately. Glad you got your answer, BAB. Larry, they are removing themselves. But I bought my antennas in 2008 and they're going on their 6th season of episodic work. Except for walkaways, I take the antennas off their masts each night (or morning on this job). I then strap them under a bungee on the cart. Yes, the nuts are working themselves out (usually, the screw stays in place and I find a wandering nut on my cart), but it's been a lot of wear by the user, too. I'm not going to change my antenna orientation, so I might just put lock tight in. If I get around to it. Thanks, Josh Quote Link to comment Share on other sites More sharing options...
BAB414 Posted September 6, 2014 Report Share Posted September 6, 2014 Just to update everyone here, the 6-32 nuts I ordered are too wide in diameter. I'm going to try #4 nuts. Thanks for the info though. Quote Link to comment Share on other sites More sharing options...

I will look into nylock inserts for those nuts. They should not work loose on their own, 6 years or not. Send me an email at larryf@lectrosonics.com with a mailing address and I'll send you 9. One for the nut that hides itself. Best Regards, Larry F p.s. congratulations! Quote Link to comment Share on other sites More sharing options...
Joshua Anderson Posted September 7, 2014 Author Report Share Posted September 7, 2014 Congratulations! Thanks! And Thanks, Larry. I'll send you an email. But if there's a limited supply, maybe send them to BAB. I've been making do and don't want to piggy back on BAB's question about them.

BAB414 Posted September 7, 2014 Report Share Posted September 7, 2014 Hey no worries Josh, but thank you for the thought. Take em. I'm going hardware shopping today. Quote Link to comment Share on other sites More sharing options...
johnpaul215 Posted September 7, 2014 Report Share Posted September 7, 2014 Just for future reference, in a pinch a place like Pep Boys / Autozone will often have these nuts&bolts as well. Sometimes they are a lot closer when you are on location. Quote Link to comment Share on other sites More sharing options...
BAB414 Posted September 9, 2014 Report Share Posted September 9, 2014 So the screws I'm talking about are the ones below the ones you guys are talking about (see the image in my pervious post). I've tried #4-40 nuts but they're still too big. Anyone know these dimensions? Quote Link to comment Share on other sites More sharing options...
LarryF Posted September 9, 2014 Report Share Posted September 9, 2014 Hi Bab, The screws are a 2-56 9/16" long stainless steel flathead screw. Our part number 28732. If you can't find them, email me your address at larryf@lectrosonics.com and I'll send you 9, eight to use and one to lose.

BAB414 Posted September 9, 2014 Report Share Posted September 9, 2014 Thanks Larry. That's what I needed to hear. I'll let you know. As always, loving the customer service! Quote Link to comment Share on other sites More sharing options...
