Anyone gotten cracks in their shops concrete floor from using red heads

[Cgotto6]

Tackit, When Cgottosaid said oversized hole in a earlier post I'm pretty sure what he meant was to make sure the hole in the steel plate was at least a 1/6" bigger than the hole that you drill into the concrete, Otherwise the anchor itself will get caught on the steel plate.

The anchors are a tad bigger than the hole you drill in the concrete.

Like S Berry said, Do not pilot drill and use a 1/2" bit for a 1/2" anchor.

Cgotto6, I have never heard of a ROTO Hammer, Here in the big city we call them a Hammer Drill.

Everything you just said us correct. Thanks for clarifying. Over size the flange hole so the drill bit and anchor both freely pass through. If you do you risk cracking the carbide tip. I have heard them called a hammer drill also, but around here roto hammer is the common name. I wonder if the first one made was branded or named roto hammer? Or us Washingtonians are just nuts haha.

Thanks Portable Welder for pointing that out, the way I read Cgoto6's comment I was going to drill a 9/16 hole in the concrete, you saved me from causing what could have been a disaster. Thanks to you Cgoto6, Cary and the rest of you good people. I understand completely now what guys are saying. I'm glad I asked, it proves there is no such thing as a dumb question.

The son called me back last night and said he has both a hammer drill and a Roto Hammer with the SDS bits. He's going to bring them to me when he gets a chance. I still have to find the red heads, might have to order them since we are a small farming community with only one hardware and one lumber yard. Ordering takes about a week if they can get what I need. When I'm done I'll post pictures with a load on the crane.

Here is a Popular Mechanics review on both kinds of drills.

Cgoto6 because you are in Washington are you using Seismic Trubolts? I want to buy the exact kind you use because of the good experience you have with them.

[Cgotto6]

I just use regular old red heads. Nothing more than their standard.

[Portable Welder]

Tackit, Chances are your hard ware should have what you need ask for a wedge anchor, Red head, Trubolt, hilti and several others make them.

They might also try to sell you a sleeve anchor which looks alot alike and does about the same job.

Either one would work for your application.

Thanks guys. I always tend to make things more difficult when I'm not comfortable with my knowledge on something or I have little or no experience doing something for the first time.

If I was drilling in wood or even deep in steel I wouldn't be so anxious.

Here's some pics of the different thru bolts. I'm going with SS since the floor is always damp during the winter months and I like to wash the floor with a hose from time to time.

I ordered 4 SS Red Head #SWW 1226 1/2 X 2 3/4 long bolts from Fastenall. Lucky they had a broken open package, a bit more than $4 a piece + SH and they're going to send them to the house. The cost of gas to go get em would cost me that.

TxDarth is that a frustrated mechanic hanging from your ceiling in the 1st pic?-Meltedmetal

Nah....I just connected with that ad campaign from Casterol "thinking with your dipstick" - thought it made sense.

Glad you got it figured out. If this is your first experience with wedge anchors you will be pleasantly surprised how easy and well they work.

Fastenall came to my rescue, they found a store that had a broken open box of SS Trubolts so I only had to buy what I needed instead of a whole box. Fasenall direct shipped them to me. No store within 50 miles of me had SS Trubolts so I was glad to pay $15 shipping and handling to get them to the house, gas to go get them at the closest Fastenall store would have cost me that.

Thanks for the help Cgotto6 and everyone else. I feel better about doing the job after talking to you guys and doing some reading on Red Heads website.. The internet sure is a great help, I don't know how I would get by without it now.

The son is going to bring his drill to me when he gets a chance. He bought a new 1/2" SDS plus bit for the drill so I should be good to go.

[tackit]

Here's the first job for the table crane after the Trubolts are embedded in the floor.

I'm going to take the 48" mower deck off my Snapper 2003K Z Zero Turn mower and use the table crane to hold the mower deck up so I can work on it comfortably. I need to change the blades and clean repaint the underside of the deck again.

For the guys that suggested all thread. Terrible idea. Especially on something that someone wants to unbolt eventually. My experience with that has been a lot of them twisting off even with the concrete, and when that happens replacing a handrail on very little space to redrill its a royal pita. Unless your using gr8 all thread... which I don't see very often. I just like to do and to see people do things right the first time around

Weldon have you ever came across hand railing mounted in sulfur?
