Wood screw shank size
I went to the local Ace store today and bought a box of wood screws,
size 10, Hillman brand. When I brought them home I decided to check the shank size, and was surprised when they came in a little small, about 0.150", instead of the 0.190 that I was expecting. https://i.imgur.com/xlke7UK.jpg Thinking I might be losing my mind, I measured an old wood screw that I had laying around, which my mind told me was a #10, and it measured 0.190". I even called the local fastener store, and they confirmed that 0.190" (or 3/16 as they put it) is the proper shank size for a #10 wood screw. So what's the deal now, did I end up with a mislabeled box of wood screws, or did someone change the specs on these things while I wasn't looking? Jon -- puzzled |

Oh, they are definitely going back, that is for sure, and if I'm not too lazy I probably should ask to speak to the hardware manager. Jon |

Home Depot quality. That's all that can be said for them. On a standard wood screw, the shank should be the same diameter as the major diameter of the threads. On your screws, it's the same as the minor diameter of the threads. That's normal for deck screws and drywall screws, but not for standard wood screws. John |

The minor diameter is correct, coming in at 0.130, so at least they got that right. I can't be the first guy who has noticed this, but I'm guessing most people just maybe don't care. Still, why don't they just sell the proper size screws and raise the price fifty cents or whatever it would have to be. *******s. Jon |

Perhaps the metal is stronger, thus the smaller diameter. I don't remember the last time I bought off-the-shelf Hillman type fasteners. Technology has left them in the dust. Specialty screws like Spax, GRK, HighPoint, Kreg, FastenMaster and others have made standard zinc screws the floppy disks of fasteners. The last package of cabinet screws I bought from GRK were about half the thickness of a zinc screw of the same strength. I used structural fasteners for my post/beam outbuilding this summer. They were almost half the thickness of equivalent lag bolts or galvanized bolts, but rated much higher in both sheer and tensile strength. For standard wood screws, I either buy from McFeely's website, my local woodcraft, or the specialty shelves at Lowes or Home Depot. Run-of-the-mill zinc screws are my absolute last choice and I always feel like I'm being paid back for poor decisions in life whenever I'm forced to use them. :-) -- -MIKE- "Playing is not something I do at night, it's my function in life" --Elvin Jones (1927-2004) -- http://mikedrums.com ---remove "DOT" ^^^^ to reply |

If there's sideways loading on the screw, you want the shank to bear against the sides of the hole. You don't want all the load to be carried by the screwhead bearing on the countersink. If the screw is purely in tension, then it doesn't make any difference (as long as the strength of the shank is still adequate). Granted, for most any application where you did have a sideways load you wouldn't use a Home Depot grade screw anyway (and it would likely be stainless or silicon bronze, not a common galvanized screw).

A smaller diameter than the clearance hole means the shank of the screw takes sideways loads on a small part of its area (and lbs/sq. in. stress is higher). That will crush the adjacent wood fiber and prevent the item from becoming a treasured, intact, antique... rather, it's another old creaky chair/desk/gibbet. Inexpensive (sheetrock-style) screws work OK for holding a glued joint shut, and the glue prevents shifting, but that IS NOT always what the designer wants. |

For good holding power where appearance is not important I've sometimes used the Tex lath screws. The washer head is that much more resistance to twisting, they're cheaper than Kreg screws, and the washer is larger. |

The old hardware often allows for dating (date range) an old piece of furnitu handmade vs production screws and nails (fasteners), hinge and pull styles/designs, etc., similarly as the woodwork, itself, design/styles. Even tool marks can aid in determining interesting/relevent aspects of an old piece. Sonny |

"tem·po·rar·y ˈtempəˌrerē/ adjective 1. lasting for only a limited period of time; not permanent. "a temporary job" synonyms: nonpermanent, short-term, interim" You are using your pocket screws as temporary fasteners (and in hidden locations). Norm's brads are still in place, they are permanent. My quibble with Norm's word choice was that he did not say "These brads will be sufficient to hold these parts together while the glue dries, if I am careful not to stress the assembly." (And he used them in very visible locations). |
