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.

Aluminum Phillips Flat Head Screws
Undercut Profile
Standard Profile
Aluminum screws are one-third the weight of steel and have good corrosion resistance. They’re angled under the head to sit flush within countersunk holes. Length is measured from the top of the head.
Screws with an undercut profile have a shallow head for use in thin materials.

Aluminum Slotted Flat Head Screws
Standard Profile
Undercut Profile
Aluminum screws are one-third the weight of steel and have good corrosion resistance. They’re angled under the head to sit flush within countersunk holes. Length is measured from the top of the head.
Screws with an undercut profile have a shallow head for use in thin materials.
