Fix It! Don't Toss It
Tossing broken things costs money and wastes resources. Instead, you can fix them! The process is easy -- if you understand fasteners!
For example, a cabinet drawer may need the glide or a screw reattached or replaced. A shirt with a button missing simply needs a button reattached. A broken dish needs the broken part reattached. Most stationary household things like these can be fixed with fasteners, either mechanical fasteners such as bolts and screws or chemical fasteners like adhesives.
There is a wide variety of mechanical fasteners available for do-it-yourself repair including nails, screws, bolts, and anchors. Your home has hundreds of fasteners in it, holding walls together, binding appliance components, keeping the floor from moving underfoot, and even fastening sleeves on to clothing. All fasteners have a single function: to hold two or more things together. When they don't, something's broken.
Fasteners include nails, screws, bolts, nuts, adhesives, and thread. Adhesives and glues are chemicals that attach the surfaces of two or more components. Fasteners are easy to use and will help you fix hundreds of things around your home, so let's take a closer look at them.
Nails are thin, pointed metal fasteners driven with a hammer to join two pieces of wood. There are dozens of varieties of nails, depending on the specific purpose. There are special nails for masonry, roofing, finishing, and other common applications. Nails are classified by the size of the shank and the shape of the head. The most common type is called common, with large, flat heads for secure fastening. Next is finish nails with smaller heads that aren't so obvious if flush to or below the wood's surface. Nails are sized by length, indicated by a d or "penny." A 4d nail is 1-1/2 inches long; an 8d nail is 2-1/2 inches long.
Screws are pointed-tip, threaded fasteners installed with a screwdriver. The type of screwdriver used depends on the type of screw head: Round- and pan (flat)-head screws require a straight-tip screwdriver; Phillips-head screws require a Phillips screwdriver; and square-head screws require a square-drive screwdriver. Wood screws fasten wood, and sheet-metal screws fasten metal. Screws are sized by length. Screws are stronger than nails and easier to remove.
Bolts are flat-tipped, threaded fasteners that use a threaded nut to attach wood or metal together. A washer may be placed under the bolt head or the nut for a firmer fasten. Bolts are classified by the type of head. Stove bolts and machine screws (actually bolts) are turned with a screwdriver. Hexagon- and square-head bolts are held in place with a wrench while the nut is turned to tighten. A carriage bolt's head imbeds itself into the wood when the nut is turned. Bolts are sized by length and thread. Bolts are stronger than screws.
You can use many other practical fasteners. A lag bolt is a bolt head with a screw body. An anchor is an addition to a bolt or screw that helps anchor the fastener in a hollow wall or door.
Thread is a fastener for clothing and upholstered furniture. Thread is a long strand of fabric installed with a needle, either by hand or by a sewing machine. Thread is sold by fabric (cotton, nylon, polyester, etc.) and thickness (Tex or T). Cotton wrap polyester is used in making a wide variety of clothing. T-18 thread is light weight and T-50 is medium weight. Thread needles are rated by the eye size, shaft length, and purpose.
Here's an easy fix-it tip: Velcro and other loop-and-hook fabric products can be used for quick fixes. You can use it to fasten toys, fabric, shoes, wall decorations, and many other things. Velcro is a trademark name for nylon fabric that can be fastened to itself. The back sides of the Velcro are fastened permanently to the object to be fastened, and the front sides of the Velcro adhere to each other when they touch.
Adhesives secure the surfaces of two materials together. There are many types of adhesives, most of them designed for use with specific materials and under specified conditions. Adhesives come in liquid, solid, or powder form, and some require a catalyst to activate them. Select adhesives based on their characteristics, strength, setting time and temperature, and bonding method. For example, cyanoacrylate (instant glue) is preferred for permanently bonding rigid plastic parts that don't face temperatures over 150 degrees. Some adhesives are waterproof while others are not; some need to be held together (clamped) while drying and others don't. Read the instructions on the label for the appropriate application and use.
Fixing things that break can be easy -- once you know about fasteners. So, next time something around your home breaks, try fixing it instead of tossing it. It's fun -- and it can help save the environment!

Why do the heat ranges of spark plugs have so much ability to damage an aluminum piston when plug is so small?
. . . when the cylindrical exterior surface areas of the spark plug that project into, and screw into, the cylinder head are together so small compared to the huge interior cylindrical surface area of the cylinder wall for absorbing the heat and also having the water jacket/air cooling fins just outside it? Isn't surface area the key factor in the rate of heat absorption/ability to dissipate heat, when both materials (cylinder wall, and spark plug body) are metals and therefore good heat conductors?
this is overcompensated by the SHAPE of the combustion chamber which helps to quench the explosion. less quench, more heat is produced in the combustion chamber which requires a lower heat range to prevent plug blowout and detonation.
more quench requires a higher heat range to keep the plug hotter and in its effective operating range for proper combustion of the air/fuel mixture.
you are looking at the picture on a whole, you have to remember that an engine operates at least at 500rpm. thats 500 times that cylinder is firing per minute...and thats only under no load idle.
you put a load on it and as the engine accelerates, the timing changes accordingly and you have to have a spark plug that can accurately function in the engine parameters.
this is about the broadest way I can explain this without getting into thermal dynamics...much less forced induction engines, where plug heat range is MUCH MUCH more important to prevent detonation or high exhaust temps which is when you start burning holes in pistons but this is also affected by air/fuel ratios.
not to mention...spark plugs do NOT protrude that far into the combustion chamber. pretty much all threading is in the thread wall of the cylinder head. you want the plug thread flush with the combustion chamber and only the electrodes protruding into the combustion chamber to prevent the plug thread wall itself from becoming a hot spot which will lead to detonation.
not only this but obviously if the plug protrudes too far and either contacts the piston @ whatever rpm it is metal on metal SLAMMING into each other. something will break. usually the plug itself which then bounces around in the piston as the pieces cant escape the valve opening and thus it just tears stuff up.
think about coins in a blender or garbage disposal. that is havok on a massive scale.
