M3X0.5 Flange Button Head Screw - A4 Stainless ISO 7380-2

Allen socket flanged button head machine screws have a built-in washer that ensures superior force distribution over a greater area, eliminating the need for a separate washer.

The smooth head design gives a neat, professional finish free from sharp edges and can be used with many different styles of locking and non-locking nuts.

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.

Also known as corrosion resistant metric integrated flange button head, rounded head machine screw. .

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.
