Stage 8 fasteners

[Rut]

Has anyone used Stage 8 fasteners? It's a hex bolt with an Allen head center to help speed screwing it in or out.

Hi Rut,
Are you thinking socket head screws or maybe button head cap screws?
If so, Fastenal has them. I have used both of these often working in machine shops building custom machines. They give a clean appearance and work well where there is limited clearance for a wrench or socket.



Example is on this tool I designed built and patented.

Tom,
these are hex head bolts with an Allen head incorporated inside the hex head. There are certain applications like the heater, MC box, heater valve, etc. that I thought might benefit from using these.

That i interesting. Thought I had seen about everything but have not seen them. I will keep that in mind as I look for other things.

I hadn't heard of these until your post. They sound interesting. It looks like they have found common use where locking fasteners with indicators is of interest . I found lots of pictures showing them used on exhaust flanges and headers.

That look's like a pretty slick miter saw, Tom. Not easy to come up with something that is patent-able now day's.

I did my Sprite after working on Harleys for 10 years. I used the socket head and button heads extensive. I liked the black look. They do have to be painted they will rust.

I've used the stage 8 bolts before... They work good for header bolts, just don't forget to loosen the inner locking bolt before loosening the outer bolt... If it's an aluminum head, you'll have a bad day, ask me how I know. Tore the threads all to ****
