    Wood Screw Information and Specifications

    SCREW SIZING

    The general size of a screw is given a number. As the number increases, so does the size of the entire screw, both head size and shaft size--but not length. Therefore, a #8 screw is about twice the size of a #4 screw, but may be the same length. Wake Up!-- This is important.

    Most wood screws have a common "pitch" to the threads, but some have a thread with a steeper incline. We simply call this a "fast" thread, but they are technically Type A screws.Think of this as a road going up a mountain; the steeper the road, the sooner you get to the top. Most of the screws for mounting hinges are self-tapping (they tap their own mating threads in wood) type AB (they have more threads per inch and are more effective in brittle materials like wood than Type A). For more info on this, see screw types section.

    Also in reference to threads you will see "8-32". This is the common knob and pull screw thread. The "8" refers to the size (diameter) of the screw, and the "32" means it has 32 threads to the inch. The diameter is measured at the shank of the screw.

    Screws are sized by gauge number and length. For example, an 8 gauge screw with 32 threads per inch and 1" in length would be written as: 8-32 X 1". However, most wood screws do not include the threads per inch measurement and would just be listed as 8 X 1". If the gauge number is not known, simply measure the diameter of the shank in inches and round to nearest listed number on chart below for screw number identification.

    *Shank diameter is measured on 
    the smooth portion of the
    screw above the threads.

    *Root diameter is measured 
    between the threads and does 
    not include the thread height.

    • The length of screw is taken from the surface of the material to the point of the screw. See illustration below.
    •  .
    • Thus, a 6 gauge screw with 15 threads per inch and 1 1/4" in length would be written as: 6-15 X 1 1/4"

    And here is an extra tid bit, this is a formula for obtaining the diameter when you only have the screw number.

    Multiply the screw Number by 13 and add ".060.

    Examples -  

    (No.) 8 x 13 = .104 + ".060 = ".164

    (No.) 2 x 13 = .026 + ".060 = ".086

    SCREW TYPES

    Basic Types of Wood Screws

    Wood screws are classified by the type of drive, the shape of head, its length, and whether it is designed for wood or metal; this page refers to wood screws only.

    Types of Drives

    Driver refers to the indented shape on the screw head used to turn the screw. There are many different types of drives. Here we are only covering the four most used drives. These include slotted (flathead), phillips (crosshead), square, and pozidriv. A brief description of each drive is below with a picture at the bottom to illustrate each ones unique design.

    SLOTTED/FLATHEAD: This is the original screw drive. You find these everywhere, though the practice of using screws with slotted drives is on the decline because the screwdriver slips out of the slot, particularly when you are applying heavy torque to really tighten down (or loosen, for that matter) these types of screws.

    PHILLIPS/CROSSHEAD: This screw drive type is very popular - and again, you find them in a very wide range of applications. Common sizes are Phillips  #1, #2 and #3. The most common Phillips size is #2.

    SQUARE: Square recess are being used more and more as they are very resistant to cam-out, which is a fancy way of saying the tip of the tool does not slip out and mar the screwhead very easily. Commonly found in two sizes: Square #2 and #3.

    POZIDRIV: This screwhead isn’t seen very often in the U.S.A., though it is very common in Europe. It looks a lot like a Phillips screwhead, but it includes 4 more contact points. Common sizes are Pozidriv #1, #2 and #3.

    screw drives

    Head Types/Shapes

    Screw head types refer to the shape of the head at the top of the screw. There are many different head types as well. Again, we will adequately cover head types, but only the most generally used.The shape of the screw head can be described as flat (countersunk), oval, round, pan, truss, button (dome), etc. Detailed descriptions for each of the ones listed are below. Looking at the drawings should make the designs of each self-explanatory.

    FLAT/COUNTERSUNK: Supplied to standard dimensions with an 80' to 82' angle to be used where finished surfaces require a flush fastening unit (concealed below woods surface). The countersunk portion offers good centering possibilities.


    OVAL: Fully specified as "oval countersunk", this head is identical to the standard flat head. but possesses. in addition, a rounded, neat appearing upper surface for attractiveness of design.


    ROUND: Not recommended for new design (see pan head). The round head rests on the surface of wood. This was the most universally used in the past.


    PAN: Recommended for new designs to replace round, truss and binding heads. Provides a low large diameter head, but with characteristically high outer edge along the-outer periphery of the head where driving action is most effective for high tightening 'torques. Slightly different head contour where supplied with recessed head.


    TRUSS: Also known as oven head, stove head, and oval binding head. A low, neat appearing, large diameter head having excellent design qualities, and as illustrated can be used to cover larger diameter clearance holes in sheet metal when additional play In assembly tolerance is required.Suggest pan head as a substitute.



    BUTTON/DOME: Cylindrical with a rounded top.

    Threading and Point Types

    Most wood screws have a common "pitch" to the treads, but some have a thread with a steeper incline. We simply call this a "fast" thread, but they are technically Type A screws.Think of this as a road going up a mountain; the steeper the road, the sooner you get to the top.

    Also in reference to threads you will see "8-32". This is the common knob and pull screw thread. The "8" refers to the size (diameter) of the screw, and the "32" means it has 32 threads to the inch. Most of the screws for mounting hinges are self-tapping (they tap their own mating threads in wood) type AB (they have more threads per inch and are more effective in brittle materials like wood than Type A)

    Threading on the shank is designed specifically for wood; wood threads have a tapped screw while sheet-metal screws have mainly a parallel thread. Wood type screws are also normally used for securing into wall plugs. Screws for chipboard usually have 2 threads the full length of the shank.

    Miscellaneous

    The most interesting screw here, if there is such a thing, is a variable length break-off knob screw. If you do not know exactly what length screw will work, order these and break them off where you need them. A unique design allows this to be done without damaging the threads.

    • And here is that famous break-off knob screw. Break-off screw 8-32 x 1 3/4" zinc plated. Break-off points 1", 1 1/4", and 1 1/2".
    • screw information
    • Perfect solution when your not quite sure which screw length you require.
    • Simply grip the section below the break point you choose with a pair of pliers, and break off.
    • Do not grip threaded section you want to use with pliers as this would damage the threads.
