SST-50 EDC Ti screws ?

[tino_ale]

Hi all,

Mac would you mind let us know what are the Ti screws you are using on the SST-50 EDC clip ?

I think they look really nice and they have a remarkably low profile.

Thanks

They are the same as McGizmo clip screws, with a lower dome. You can buy them at the Sandwich Shoppe.

McGizmo screws are 4-40 x 3/16" Button Head Screws from Lunsford but the SST EDC's screws have a lower profile and this is why I like them better

Are they 4-40 x 3/16" too ?

BTW I could not find neither Mac's or McGizmo screw on the sandwich shoppe. They have some screws but not titanium.

The 1st run of the SST-50 used the lunsford Titanium Screws but that stopped after the 1st run as half the screws I received would not work in the titanium lights. I spoke with Lunsford and there said in order to use their screws in Titanum they would need to make me a *Special* batch with a minimum order and 2+ months lead time. All screws are SS 4-40 x 3/16 that I bead blast to match the clips.

I never really like the Lunsford screws quality as you could see the broach marks in the hex area not to mention the 50% fail rate if installed into Titanium.

Thanks for the info, the SS screws your use look great. Can we get spares from you or from elsewhere ?

Also what do you mean by "do not work in titanium" ? How come Lundsford needs to make a special run of screws if used in Ti ?

I purchase the screws from MSC they are just standad 4-40 x 3/16 SS screws that I bead blast to match the clips. If you wanted spares they can be purchases from MSC for $6 per 100 pieces.

As for the Lunsford screws they state that in order for them to work in Titanium the have to make them slightly undersize.

Somewhere in the McGizmo forum, Don already explained about "his" screws, which may be the same, I don't know...

Most didn't work for him either, they must have extremely low tolerances for ti and that's just not the case with stock screws. As Don makes a few lights more, he has his screws made in extra batches, IIRC they are not especially made for him, but hand-picked.

I'd be OK with ss screws everywhere, I doubt I'd ever notice a difference whatsoever, I normally don't use the clips, on a ti light they are a must for the optic though, nothing's like a nice clip to dress a light and the one of the EDC-SST50 is indeed very nice (and tough if you need it) and worth the extra money!


The person at Lunsford that makes the screws told me he specially makes the screws for Don.

Permatex anti-sieze makes the titanium screws a lot easier to work with.

Sorry, I thought the second item on this page was the same thing as what Mac was working with: http://theledguy.chainreactionweb.com/index.php?cPath=48_42 They have a similar lower profile, anyway, and they fit just fine when I tested them. But...YMMV, as always.
