I'm getting ready to install my underbelly cover -- there will be aluminum C channel beams (to support the foam panels and the coroplast under-skin) attached to the underside of the trailer's frame members. Some of the steel frame is pretty beefy -- either I beams or box beams.I know some folks have used beam clamps to attach the C channel to the chassis, but I am very risk averse and want it all to be screwed down in a bomb-proof way.I thought about quarter inch bolts -- yes, that would work, but that would entail a lot of time drilling up into the frame while laying on my back with bits of metal falling in my face. Sounds like fun! Plus it involves drilling big holes into the frame, potentially weakening the beams.So I am leaning toward self drilling self tapping screws. I am planning to drill a pilot hole -- I will experiment to see what size pilot will give me the best results.I am leaning toward hex head screws -- I have a tendency to strip Phillips screws when working upside down, and hex heads give me a nice solid grip, so that I can snap the head off a few of the screws by over-tightening them. (I wish I were kidding -- I have a terrible problem of knowing when to stop tightening things. My wife calls me "The Great Twisto" in honor of the things I have destroyed.)But here come the questions -- first, is there a particular brand of screws that you prefer?Do you use an impact driver to install the screws, or a drill motor with a socket?In thin metal (let's say a sixteenth), do you need to drill a pilot hole?Thanks in advance for your advice. I am guessing that there are quite a few of us who are not experts in using this type of screw, so your comments will be appreciated!
Self-tapping screws and self-drilling screws are often confused with each other. Both of these screw types are commonly used in construction, commercial, and industrial applications. Continue reading to learn what self-tapping and self-drilling screws are, the applications they are designed for, and the differences between these fasteners.
Self-tapping screws, also referred to as tapping screws or tapper screws, require an initial pilot hole before they can be installed. However, they are designed to swiftly cut their own threads while being fastened.
What are Self Tapping Screws Used For?
Self-tapping screws are typically used to drill through thinner sheet metals and other substrates including wood and some plastics.
Tapping screws have the best performance when the punch hole is drilled to the correct size. If the hole is too big, the screw won't thread correctly and will become loose. If the hole is too small, the screw can break or cause the material to split or crack.
Common Applications Include:
Self-drilling screws, also referred to as Tek screws, feature a tip that is shaped and functions similarly to a twist drill bit. The sharp point and cutting threads eliminate predrilling a pilot hole into the material. The screw cuts its threads and creates a hole in the material all in one action.

This screw design also has a notched area in the tip of the screw that receives wood chips or metal filling to create space to drill the screw all the way into the material.
What are Self Drilling Screws Used For?
Self-drilling screws are typically used on applications for quick drilling into metal-to-metal, wood-to-metal, and light-density materials.
Common Applications Include:
Self-drilling screws are typically manufactured out of hardened steel and metal. The rule of thumb for using self-drilling screws is to never drill into a material that is harder than screw material. If the material is too hard, the tip of the screw will become dull and won't drill into the material.
If you use self-drilling screws to drill into very thin wood, we recommend you use a standard drill bit first to prevent splitting and cracking of the wood.
Both self-tapping and self-drilling screws are technically self-tapping because they cut their own threads. The main difference between them is the function of their points.
