Aluminum Socket Head Screws
Fully Threaded
Partially Threaded
Aluminum screws are one-third the weight of steel and have good corrosion resistance. Length is measured from under the head.
Screws with a blue-anodized finish are easy to distinguish.
Coarse threads are the industry standard; choose these screws if you don’t know the threads per inch. Fine threads are closely spaced to prevent loosening from vibration. They are not compatible with coarse threads.
