I used the stickscrew at a previous employer, we used them to assemble a sheet metal chassis. We asked them to paint our screws black to match the metal. I though they worked very well. As Phil said, they are a great labor savings in terms of labor.

I have a trial one on my desk, but I haven't actually tried it out, because a lot of screws in our chassis are seen from the outside and the hex shape looked a little funky and I was worried the breakoff point between the screws might not be always totally clean. -----Original Message----- From: Phil Nutting [mailto:[log in to unmask]] Sent: May 18, 2001 8:40 AM To: [log in to unmask] Subject: Re: [TN] RivScrew for Assembly Michael, Yes. We switched to RivScrews to mount our fans and fan grills to the chassis to eliminate the hand work of inserting and tightening the screw, flat washer, lock washer and nut. They work well, but with a cautionary note. Carefully size the fastener to the hole size. In the case of our fans with plastic bodies we had cracking around the corner where the RivScrew was inserted. Our solution to date is to switch to a plastic snap-in fastener, in some applications, made by Fastex and Richco. The RivScrews worked well and saved a huge amount of labor. One down side (for us) is the quantities that Avdel Cherry wants to sell the fasteners in, 50K per order. This may be fine for your application, but with our production level one order would have lasted us years. We were able to get around this by buying from a local distributor (Accurate Screw in Boston). I experimented with using the RivScrews for fastening TO-220 and TO-247 devices to heat sinks. My Engineering department never bought into the process. However, I'm told this is "an industry standard". We found that in some applications the Chobert fastener worked well or better due to sizing. Please carefully size the mandrel to the fastener. We had an application were we used an oversized mandrel in a fastener and ultimately it ripped the fastener lengthwise as we were over stretching [forming] the metal. Tooling is a bit pricey, but if you are making bunches of chassis they may be cost effective. There is another fastener called "Screw Stick" which may also work in your application. Unfortunately I've forgotten who makes them. Does anybody else have experience with these?

We have a unit that requires over 200 screws to assemble. I would like to use RivScrews to cut down on the assembly time. Does anyone have experience replacing screws to build up a chassis with RivScrews? Thank you.
