Help installing Red head Drop in anchors

[bubinga]

I don't have the tool, but have a metal lathe, does anyone have the tool.
do my dimensions seem about correct?
Pictures show what I have, and proposed dimensions of tool I will machine from 1/2" stock.
thanks,

You can use anything that will fit inside the drop ins. You don't need a special tool at work we just grind the threads off a rod to set it

Oh, OK, but how far do I knock the slug down, till it stops?
l could just use a punch then?
l guess the slug would bottom when it hits the bottom of the hole.

Yes, you can use a plain old punch.

Yes, the slug will bottom out. You can hear and feel the point when it sets.

The tool does make it a bit easier because it provides a visual cue.

Probably the one thing that most do not do, but should be done, is to blow or vacuum out the hole after drilling.

thanks, I will be sure to blow out the hole.
Thank You

I tend to drill the hole deeper than the length of the anchor, blow it out, and thread a nut to the amount of thread I want exposed. Hit it with a hammer until the nut stops it, then tighten the nut to seat the anchor.

Make sure that you thread the nut a few turns past the tip of the anchor, because if you hit the nut it will deform the threads.

The reason I drill deeper than the anchor is so when I remove what's anchored, I can cut the threads off and hammer the anchor to be under the surface of the concrete, and the hole can be patched flush and even.

They went in OK, I just used a punch to set them.
The material was pretty hard in sections, and the holes were a bit oversize, but they seemed to hold pretty well, in spite of the fit being somewhat sloppy.

On a related question about these anchors; what if you ever need to remove them, an easy way? Assume just drill out?

 

[bubinga]

I don't have experience removing them, but I'd bet you could thread a slap hammer Ina and slap hammer them out.
Or thread a long piece of all thread into the hole, and put an impact socket over the all thread, and a washer and a nut to form a puller.

You might be able to drill them out but I have yet to see anybody pull one out. If you no longer needed them, you could just fill the hole with grout or a product like Rock ite.

When you set them... Drill deep enough to be able to drive the anchor below the surface...

I've removed a half set one once... Hit rebar and started spinning. It's a pain. If you do manage to remove the anchor, you will have done so by breaking off the metal pieces that expand to wedge the anchor by prying twisting and pulling.

I don't think they'd come out, but if so you'd need to hit them IN first to get the wedge to let go.
