In the case of an M6 fastener, the 'M' signifies an ISO Metric thread and the '6' signifies the nominal diameter.

Our metric range of fasteners have the standard coarse pitch unless otherwise stated. A coarse pitch M6 bolt or screw will screw into any coarse pitch M6 nut.

Each fastener table is accompanied by a product photograph and lists the materials and thread diameters available for each.
Select the required material to highlight the available thread diameters. The page loads with standard A2 grade Stainless Steel preselected. Other materials are available where indicated. The material key to the right explains each available material type.
Click the desired diameter to display a page listing the lengths available in this size, from which items can be added to your order.

Fastener Material Key
A1	A1 Stainless Steel - Also known as grade 303. A general purpose grade of stainless steel but with better fabrication/machining properties than grade 304.
A2	A2 Stainless Steel - Also known as grade 304 or 18/8. A general purpose grade of stainless steel.
A4	A4 Stainless Steel - Also known as grade 316 or 18/8/3. A higher corrosion resistant, marine grade of stainless steel.
A4-80	A4-80 Stainless Steel - Identical corrosion resistance to A4-70 but with a higher tensile strength equivalent to that of 8.8 high tensile steel.
BO-10.9	Black Oxide High Tensile Steel Class 10.9 - A high tensile non-stainless grade with a black oxide finish offering limited corrosion resistance.
BO-12.9	Black Oxide High Tensile Steel Class 12.9 - A high tensile non-stainless grade with a black oxide finish offering limited corrosion resistance.
Brass	Brass - Offers an attractive, corrosion resistant finish.
BZP	Bright Zinc Plated (BZP) Steel - Non-stainless standard steel grade offering a basic level of corrosion resistance.
BZP-10.9	Bright Zinc Plated (BZP) Class 10 High Tensile Steel - A high strength non-stainless grade for screws and bolts, with a basic level of corrosion resistance.
BZP-12.9	Bright Zinc Plated (BZP) Class 12 High Tensile Steel - A higher tensile non-stainless grade for screws and bolts, with a basic level of corrosion resistance.
BZP-8.8	Bright Zinc Plated (BZP) Class 8 High Tensile Steel - The general purpose high tensile grade for screws and bolts, with a basic level of corrosion resistance.
Duplex	Duplex Stainless Steel 1.4462 - A type of stainless steel which has greater corrosion resistance than A4 / 316 and a high tensile strength of minimum 700 N/mm2. Also known as 318LN.
Nylon	Plastic (Nylon Polyamide) - A tough lightweight plastic, strong at low temperatures, with excellent resistance to chemicals, and features favourable sliding friction behaviour.
PE-Blk	Plastic (Black Polyethylene) - Has good barrier properties and good chemical resistance against acid, greases, and oil.
PE-White	Plastic (White Polyethylene) - Has good barrier properties and good chemical resistance against acid, greases, and oil.
ZnFlk-10.9	Organic Zinc Flake Coated Class 10 High Tensile Steel - A higher tensile non-stainless grade for screws and bolts. Coated with superior mechanically applied zinc with corrosion resistance lasting 480 hours in the salt spray test.
ZnFlk-12.9	Organic Zinc Flake Coated Class 12 High Tensile Steel - A higher tensile non-stainless grade for screws and bolts. Coated with superior mechanically applied zinc with corrosion resistance lasting 480 hours in the salt spray test.
