When the self tapping concrete anchor first came out I was impressed however, through the years I've become more and more disappointed with them. I follow the recommended depth penetration and even use the supplied masonry bits but the failure rate for me is high. This morning I needed to anchor a tapered ramp at a threshold so I can get a 55 gal. drum cart over it from my dust collector. Out of 4 Tapcons, 1 stripped and another snapped off. Anyone have the same 50-50 results? I just may have to pull it up, drill some larger holes and use some "drop-ins" in their place. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

We used them at work,never a fan may have been because everything had to be just right for them to work. Can't even count how many times 25 or 50 pair terminals would come off a wall as you opened it's door. Drill bits that came in every box were great though,still have some.... Older concrete seemed to create trouble too. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

Tapcons are still my preferred anchor. 1 out of 65 give me a problem. The problem is usually wrong bit for the size Tapcon 3/16 bit for 1/4"  , or the hole isn't deep enough. This is the only time in my life when it seems a hole is never too deep for me. Every blue moon i find modern concrete too dry or stucco too thick. ------------- Please support The Cystic Fibrosis Foundation 1976 Ski Nautique 351 Escort 1993 Ski Nautique purple and black 351 HO PCM |

I personally hate them. You need to buy a dozen drill bits because they are useless, and burn out too easily. I even have had the bit fall out of the drill tip. Then the screws themselves snap off half the time, or the threads strip off. I find sleeve anchors are better because you can uses an sds hammer drill which drills through concrete like butter, and the anchors hold much stronger. ------------- https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcRtW3vJrMHLdqBzndt9VX3oOpBuRopGlzKq9Ea7pAO7wnTuoD8E8g |

finally a topic that i have waited for... i despise them and keep buying them what is wrong with me. i feel like the ones that give you trouble when hanging f&m plates or wood to hold piping on concrete the ones that fail are the ones that are in a spot with no option for a different location. ------------- former skylark owner now a formula but I cant let this place go |

on another note for the trades do you guys ever get sick of buying the long tiny finder bits that bend and break? an electriction friend showed me a cool trick he grabs one of the insulation wires that hold up the insulation in the bays above your head he cuts a 45 degree cut with his side cutters and drills locator holes through wood or plaster when they dull recut and when they are junk buy a box of 100 for $10.00? ------------- former skylark owner now a formula but I cant let this place go |

Peter we had it made. The only thing we had to buy for our self was our foot wear and rain coats. The last years say from 95ish up we only had to buy our work boots. Some of us bought drywall screws to mount things to make life easier because the company only bought hex headed sheet metal screws. I remember a repair tech yelling at us because none of them had phillips head screwdrivers to remove something we had put in. He had to run around to find one which must have cut into his coffee shop time. When I started in the 70's we had no power tools just braces and ram sets. Finally in the late 80's we got our first Makita cordless drills,the ones with the internal battery,by keeping our tool expenses down for the month! ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

I think I've probably had similar success/failure rates as you have with the tapcons. I think it may have to do mainly with the concrete you are mounting them in. I work Redi-mix and there are all sorts of strengths, aggregates, and variables that make some concrete stronger or denser than others, which would cause some to bite good, some to bite too good and either strip the threads or break, and some that don't hold stripping the concrete itself. Age of concrete also may also factor in to it. You notice the holes that drill fast are usually the ones that hold ok and the ones that strip threads or brake seem to take longer to drill?. I also may be completely wrong and the tapcons are just bad! |

we used to use both those and take a set of chemical anchors with for when they fail when they work they are great when they dont its a pain in the ass ------------- 1983 Ski Nautique '2001' -Chev 350 Mercruiser -Custom Wake Tower -Custom Interior |

Brandon, It's interesting that you've mentioned the speed of drilling since thinking about it, the 2 problems I did have were on the holes that drilled slower! The slab was poured with a normal 5 bag 3000 psi and fiber just over 2 years ago. BTW, I'm going back at the ramp today with the "drop - ins" since the 2 failed Tapcons are really bothering me!  ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Same thing in Ohio..we had it made tool wise & clothing wise. Like Gary.....I have used these darn things to place alot of terminals & equipment. Found after much useage..drill the hole slow..keep the dust outa the hole & slowly 'walk' the blue screw in. LOL Gary...I remember lugging around those heavy Makitas with the battery pack slung over the shoulder! john ------------- "Loud pipes save lives" AdamT sez "I'm Canadian and a beaver lover myself"... |

X2. If your snapping the heads off, IMO, the hole wasn't cleaned out well enough with the bit and your driving them too quick. I always use SDS bits on these, so much quicker which equals cleaner and straight hole. Sounds like a advice you give on how to treat a women. . If I have had them ever slip I'll back em out and use some PL x8 poly construction adhesive. That stuff is nasty. must be Pete, here in the Midwest we Pour concrete.

+ another on poured. Must be a Midwest thing. I would think placing would be setting a prestressed panel ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |
