Materials and Finishes

Below, we list the common materials and finishes we supply fasteners in. If you're looking for something that's not on this list, please get in touch as we will be able to supply it!

Standard Materials

Mild Steel
High Tensile Steel, Grade 8.8
High Tensile Steel, Grade 10.9
High Tensile Steel, Grade 12.9
High Tensile Steel, Grade 14.9

Stainless Steel, A2-70 / Grade 304

A general purpose stainless steel which strikes a good balance between corrosion-resistance and cost.

Stainless Steel, A4-70 / Grade 316

Often referred to as 'marine grade' stainless steel due to it's excellent anti-corrosion properties, making it great for saltwater resistance.

Stainless Steel, A4-80

The same excellent corrosion-resistance of A4-70, with the added benefit of higher tensile strength.

Stainless Steel, Bumax® 88

A premium option which provides the excellent corrosion resistance of A4, and tensile strength roughly equivalent to High Tensile Steel, Grade 8.8.

Stainless Steel, Bumax® 109

A premium option which provides the excellent corrosion resistance of A4, and tensile strength roughly equivalent to High Tensile Steel, Grade 10.9.

Brass

While not the strongest material, brass is anti-corrosive and water resistant, and can also be the right choice aesthetically if the fastener is on display.

Nylon

Nylon has high tesile strength and wear resistance, as well as strong resistance to many chemicals. It is also extremely light.

Peek

A premium alternative to Nylon, Peek is stronger and more resistant to chemicals and corrosion.

Special Materials

Duplex Stainless Steel
Super Duplex Stainless Steel

ASTM A193 B7
ASTM A193 B8
ASTM A193 B8M

Hastelloy

Incoloy

Inconel

Nimonic

Nitronic

Titanium

Extremely lightweight, but also extremely strong and corrosion resistant. Titanium is the perfect option for situations where every gram of weight counts.

Monel 400

Monel 400 is strong, and extremely resistant to corrosion especially in marine settings.

Monel K-500

Monel K-500 combines Monel 400's strong corrosion resistance with even higher tensile strength.

Aluminium
Aluminium / Bronze

Zeron

Ferralium

Carpenter Alloy 20Cb-3

Hiduron

Finishes

Self Colour

A plain black finish, with no additional plating. Best suited for indoor use as corrosion resistance is minimal.

Bright Zinc Plated

Bright zinc plating offers excellent corrosion resistane, protecting the component underneath.

Zinc Yellow Plated
Hot-dip Galvanised

Galvanisation is when a component is dipped in molten zinc. This provides a higher level of corrosion resistance than standard zinc electroplating.

Silver Plated

Silver plated components are highly electrically conductive, corrosion resistant, and anti-bacterial.

Gold Plated

Gold plated components are highly electrically conductive and corrosion resistant.

Chrome Plated
Kolsterising®

Kolsterising® massively increases the hardness and improves the mechanical wear properties of a component, without affecting its corrosion resistance.

WS2 Coating

WS2 coating acts as a lubricant and can extend the life and durability of fasteners.

MOS2 Coating

MOS2 coating acts as a lubricant and can extend the life and durability of fasteners.

PTFE / Teflon Coating
Dacromet Coating

Patching
Drilling / Venting
Thread Locking
