Our stainless steel bolts are made from high quality 316L A4 stainless steel which offers very high strength and corrosion resistance. Stainless steel is a strong material which is extremely resistant to corrosion, and it requires very little maintenance. Our threads are machined to ISO/DIN standards, and they are rolled for increased tensile strength.


On leaving production, all our A4 stainless steel bolts are polished. This process brings not only a high luster and mirror like finish, but further strengthens the corrosion resistance. We offer 3 finishes for stainless steel in our catalog: Natural, Black DLC and GOLD DLC

BLACK & GOLD DLC (Diamond Like Carbon)

DLC (also known as PVD) is our ultimate finish. We are proud to offer DLC (diamond like coating) as an optional surface treatment. The advantages of DLC include a beautiful black or gold colour, an extremely hard surface which is highly scratch resistant, and the DLC process also reduces the friction coefficient which aids in a smoother engagement. The life span of a DLC coated bolt can be over 5,000 different assemblies.

NOTE: due to the technical nature of this coating, the delivery time for our may be extended (contact us for more information).

Measurement of our bolts: the measurement of your stainless steel bolt with Tapered Socket Cap heads is taken under the head and is always displayed as follows: Diameter x (Thread pitch) x Length

ExempleM6 x (1.00mm) x 30mm

  • M6 represents the diameter
  • (1.00 mm) is the Thread Pitch
  • 8 mm is the length Without head

See our article on how to measure a Bolt

We recommend the application of a small amount of copper grease to your threads to avoid any potential galling.
