Pan head screws have a standard cylindrical head with a flat top. They are the most common choice for general fastening. Truss head screws have a wider, lower-profile head that distributes clamping force over a larger area, making them a good choice for softer materials or thin panels where you want to prevent pull-through.
Yes, black zinc plating offers a moderate level of corrosion resistance suitable for indoor use and light outdoor exposure. They are not designed for direct or prolonged contact with saltwater, road salts, or harsh chemicals. For those environments, we recommend stainless steel screws.
While they are fine for occasional outdoor use in dry conditions, they are not designed for continuous exposure to the elements. If you need hardware for outdoor decks, fences, or marine applications, please consider stainless steel screws for better corrosion resistance.
The "M" number refers to the thread diameter in millimeters. For example, an M4 screw has a 4mm thread diameter. The length is measured from the bearing surface of the head to the tip. For a proper fit, ensure the screw is long enough to pass through your material and engage with a nut or a tapped hole.
Yes, but you should always use the correct Phillips bit size and set your drill to a low torque setting. Using high torque can strip the drive recess or snap the screw. For heavy-duty applications, a manual screwdriver or a controlled torque driver is recommended.
