Zinc-plated for corrosion resistance
When it comes to sheet metal screws with 1/4 heads, the option of zinc plating provides an essential layer of protection against corrosion. Corrosion resistance is a critical factor to consider, especially when working with metals, as it directly impacts the longevity and integrity of your project. Zinc plating offers a robust defence against corrosion by forming a protective barrier on the screw's surface. This plating serves as a sacrificial layer, willing to corrode itself to save the underlying metal.
Zinc-plated sheet metal screws are an excellent choice for applications where moisture and corrosive elements are present. The zinc plating acts as a shield, preventing water, chemicals, and other corrosive substances from directly contacting the screw's surface. This barrier not only inhibits the formation of rust but also helps maintain the screw's structural integrity over its lifespan.
The process of zinc plating involves carefully coating the screws with a thin layer of zinc. This layer is tightly adhered to the metal surface, ensuring that it does not flake or peel off easily. The zinc plating process is meticulously controlled to achieve the desired thickness, ensuring optimal protection without adding excessive bulk to the screw. This balance between protection and weight preservation is crucial in maintaining the functionality and ease of use associated with sheet metal screws.
Zinc plating is an effective and widely used method for enhancing the corrosion resistance of sheet metal screws. It provides a cost-effective solution, especially when compared to other protective coatings or treatments. The simplicity and efficiency of the zinc plating process make it an attractive option for manufacturers and consumers alike. Choosing zinc-plated sheet metal screws ensures peace of mind, knowing that your project is safeguarded against the detrimental effects of corrosion.

Sheet Metal Screw, Black Oxide Finish
Sheet metal screws are a type of self-tapping screw with threads that run down the entire length of the shank, making them ideal for tapping and fastening thin materials. The type of material that a screw can be used on is determined by its point style. For instance, the sharp point of a sheet metal screw aids in its penetration of the material.
Sheet metal screws come in a variety of head shapes, including truss, pan, flat, and hex washer. The truss head, for instance, has an extra-wide low-profile domed shape that is suitable for applications with minimal clearance. The Phillips drive, which is designed to prevent over-tightening, is also found on some sheet metal screws.
The black oxide finish on sheet metal screws offers mild corrosion resistance and lubricity. It is commonly applied to steel screws, which are known for their strength.
Small Parts offers a range of sheet metal screws with a black oxide finish and a Phillips drive. The length of these screws ranges from 3/8" to 2", with thread sizes of #6-18 or #8-15. The pack sizes range from 10 to 100.
