M2X0.4 Button Head Cap Screw - A4 Stainless ISO 7380-1

Allen socket drive button head cap screws are great for limited space installation areas. An allen wrench is used to install these screws. The slim design of an allen socket wrench allows access to tight locations where a traditional external hex drive bolt would not fit.

The smooth head design gives a neat, professional finish free from sharp edges, great for furniture and finish work

These bolts can be used with many different styles of locking and non-locking nuts, tightly clamping together whatever the cap screw is being used to secure.  

Also known as an rounded head button bolt, hexagon socket button head screw. Common identifying abbreviations: BH, BHCS, BHMS, SBHCS, SBHM

Material: A4 / SAE Type 316 


A4 / 316 Stainless Steel fasteners are "marine grade" corrosion resistant; suitable for salt water applications. A4 fasteners also offer increased resistance to chemicals when compared with A2 stainless fasteners.


Commonly used in wet environments. Popular across a wide range of industries: automotive, agriculture, photographic, medical / surgical,  food processing, robotics, architectural detailing, construction, healthcare, sanitary, transportation, clean energy, etc.
