Security Fastener Question

[Mick1]

I am looking at security fasteners used for lights.

The Rigid Kit
Security Nut Kit.

Same thing at McMaster Carr:
McMaster-Carr

I have a Wheeler Bit Driver Kit. It is mostly a bunch of various gunsmithing bits. Here is a link to the tool:

Wheeler® Deluxe Gunsmithing Screwdriver Set, Gun Smithing, Gun Maintenance, Shooting : Cabela's

Two of the bits look like they could work for the McMaster security bit, but I'm not sure. The Weaver/Ruger scope ring clamp bit #777-831 and the Mauser Stock Bolt Bit #117-997 are the two I think might work. (The weaver bit is in the upper left in the Image in the Cabela link above)

The CAD drawing on the McMaster site does not specify the distance between the drive holes, but does give the size of the fastener at 1".

The weaver scope bit has its drive lugs just about exactly 1 cm apart or 3/8"

I'd prefer not to spend money ordering a duplicate tool if I can avoid it. Do any of you know if these bits might work?

I can't say if any fit but I have that set and they are nice but a little soft. I've worn out 2 bits without any excessive force.

Why don't you just use tamper proof Torx?

 

[GrantK]

Security Torx can be defeated with a standard slot blade screwdriver (the pin holds the screwdriver in place).

City kid advice - sometimes you don't want to make things too hard to steal. When the kid is up and can't do it easily he will most likely do more damage doing it the hard way. Sad but true. If my goal is your lights, I WILL get them. Its the how which is the only open question.

Follow up: None of the bits in the Wheeler kit work.

Also, while the security nut kit Rigid sells indicates that the size is 1/4"-20, these nuts DO NOT fit the bolts that are supplied with the SR-M lights.

The size of the bolts supplied with the SR-M lights is 5/16"-18.
