By design, this part is a self-tapping screw that measures 3.5mm in diameter and 20mm in length. Self-tapping screws are widely used in the automotive industry due to their unique design and function. Their distinctive feature is the ability to create their threading or tap their hole while being driven into the material, hence the term 'self-tap.'

This means you can save time on pre-drilling holes and achieve a firm, tight fit. Depending on the material and specific application, these screws can also be removed and reused. They have sharp threads that cut into the material when screwed in and a pointed tip to pierce through the material quickly.

In automotive applications, the Spec. SELF-TAP Screw can be used in various areas requiring secure fastening, such as attaching components, securing panels, or fastening accessories. It's important to remember that the example part provided - the 3.5x20mm size - is specific to certain makes and models from the manufacturers above. Always cross-reference against your vehicle's manufacturer manual or advice from a professional mechanic to ensure you're using the correct part. Don't attempt to force a screw that doesn't fit, as this can cause damage.

As an OEM part, the AP8221242 screw ensures the quality and fit will be compatible with your vehicle. OEM parts are made by the same manufacturer that produced the original parts in your car, guaranteeing that they'll work as well as the parts they're replacing. This ensures the best possible alignment with the other components and a longer lifespan compared to generic or aftermarket replacements.
