A: Robertson pan head screws are ideal for woodworking and cabinetry due to their square-drive design, which prevents cam-out. Their flat, slightly rounded head sits flush with surfaces, making them suitable for visible applications.
A: The size "8 x 1/2" refers to a 8 screw diameter (approx. 0.164 inches) and a ½-inch shaft length. This size is commonly used for lightweight materials like thin wood panels or plastic assemblies.
A: Robertson screws use a square recess for better torque transfer and reduced tool slippage, while Phillips screws have a cross-shaped recess. Robertson variants are more popular in Canada and for industrial applications.
A: Pan head screws are often manufactured from steel, stainless steel, or brass, with optional coatings like zinc or black oxide. Material choice depends on required strength, corrosion resistance, and application environment.
A: While possible, pan heads are designed for flush surface mounting. For counterbored applications, flat head screws are generally preferred as their tapered profile fits angled recesses better.
