Weird screws, no idea how to remove
This is a "speed and feed" table on my Clausing 6913. It is all beat
up and a replacement was not too expensive ($21). The problem is that it is attached with fasteners that have smooth heads, mushroom shaped. No slot of any kind. I cannot seem to grab them with pliers either. Here's the picture with one of them circled: http://igor.chudov.com/tmp/Smooth-Headed-Screw.jpg The manual refers to these screws on page 24: "#2 x 3/16 P.K. DRIVE SCREW" Google does not bring up anything about these. Would anyone have any idea how to remove them. I would replace them with philips or slotted screws from Ace Hardware. But I need to remove them first. thanks a lot to all. i |

I was confused by the name, as they are not really screws, despite their name. After your post, I already drove out three of them by prying them. The fourth is just a matter of time. i |

Yep Jim and Dan, they just needed to be pried out, I thought that they
were "screws" and tried to screw them out, to no avail. The speed and feed table was reinstalled, I am very happy. The effect is awesome, like makeup on a 40 year old girl. i |

"#2 x 3/16 P.K. DRIVE SCREW" Would anyone have any idea how to remove them. I recently had the same problem. My cold chisel wasn't sharp enough, so I ground the end of some 5/16" HSS square stock to a sharp bevel, about 20 degrees. Then narrowed down the sharp edge from 5/16" to more like 1/8". This was my chisel, and with a small hammer I was able to get under the head with minimal damage to the aluminium label. To finish removal, I got some small pincers - actually from an electronics shop - and dressed the jaws on the bench grinder to remove the slight bevels along the tops of the jaws that would otherwise not allow them to get under the screw heads. As there's a spiral on drive screws, give a twist as you pull them out. Jordan |

Jordan Let me add a little warning to that otherwise good idea. HSS stores up a LOT of energy when it bends, and if it breaks it throws very sharp fragments at high speed. I found that out by not cutting a deep enough groove all the way around before breaking a short piece off with a hammer. jsw |

Well, the old table lasted 43 years. If the new table lasts 43 more years, I will be replacing it at the age of 81, if Clausing still has it that is. At that age I will have plenty of time to re-remove the "screws". I probably will forget all about how to remove them, by then. i |

http://igor.chudov.com/tmp/Smooth-Headed-Screw.jpg
Ran into these same or similar type screws on an ignition rebuild (Kasasaki Super Sherpa motorcycle) this past year. Seems they use fasteners that screw in and when thight, the head breaks off so that you can't get them out. The only problem is I needed to get them out, eh? Drilled them, but had to disassemble a whole lot of stuff to make room for a small hand drill to get in there. -- Regards, Joe Agro, Jr. (800) 871-5022 01.908.542.0244 Automatic / Pneumatic Drills: http://www.AutoDrill.com Multiple Spindle Drills: http://www.Multi-Drill.com Production Tapping: http://Production-Tapping-Equipment.com/ Flagship Site: http://www.Drill-N-Tap.com VIDEOS: http://www.youtube.com/user/AutoDrill V8013-R |

Replacements are listed as either drive pins or drive screws, from the usual suspects, MSC, Grainger, etc. If you can't get a grip on the edges, I've either wedged them up with a knifeblade or filed opposing flats so a grip can be had.

The problem is that it is attached with fasteners that have smooth heads, mushroom shaped. No slot of any kind. I cannot seem to grab them with pliers either. These are "drive pins", often used for this purpose. Mostly, you need to work a chisel gently under the head, then pull with whatever can get a grip. Diagonal cutters can be useful, or prying with a pair of flipped-over chisels, using the bevels as a fulcrum. Of course, if you break off the head, you are in big trouble. Generally, these things don't get very tight in the hole, but a bit of rust could change that. Jon |

See if you can grip them with a vice-grip. slowly turn and they are
fast spirals. They are tapped in with a 'tack hammer'. Martin Ignoramus14738 wrote: This is a "speed and feed" table on my Clausing 6913.

Lay them flush to the surface and squeeze while turning. I have removed hundreds that way. These fasteners are used to make it difficult to remove without damaging the plate.

To remove them -- get a flush cutting pair of dikes, and grip as close to the surface as possible -- or, since you have a replacement data plate, just slide a screwdriver under the edge and walk up to the drive screws. I've got two sizes of them, and if you happen to need a size which I have, let me know and I'll send you more than enough to install the new plate. If you pry them out with the screwdriver under the plate, you probably can re-use them -- but measure the length under the head and the diameter of both the "thread" area and the pilot so I can compare them to what I have. Just send me an e-mail. (Of course, it may be a few days before I can mail *anything* given the threat of heavy snow here. :-) *Don't* put slotted screws in there.
