## Description

All pictures represent actual product. A button head socket cap screw is a screw with a button head and hexagon drive for tightening with an Allen-style wrench. This screw carries a recessed internal socket drive to add strength. The 18-8 stainless steel material provides strength and offers good corrosion resistance in many environments. The material may be slightly magnetic. The button head is round with a low profile, short vertical sides and is suitable for light duty applications. The internal hex drive, also known as a hex-socket drive, has a hexagonal slot that requires an Allen key driver, also known as a hex key or Allen wrench. Socket cap screws are threaded fasteners that have a cap head with an internal socket drive for installing in areas with limited side clearance.

    The cutest screw heads

You need a very tiny alan key to tighten these, but if you have one lying around, these are great quality screws to fit into a tiny tiny hole.
