M6 x 16mm Hexagon Head Set Screws – A2-70 Stainless Steel DIN 933

Compact Stainless Steel Fasteners for Secure and Precise Assembly

For applications requiring a shorter fixing without compromising on material quality, our M6 x 16mm stainless steel hexagon head set screws offer a practical, corrosion-resistant fastening solution.

Manufactured from A2-70 (304) stainless steel and conforming to DIN 933, these fully threaded hexagon bolts are commonly used in engineering, machinery manufacturing, metal fabrication and general assembly work.

With a nominal thread diameter of 6mm and an overall fixing length of 16mm measured beneath the head, these stainless steel setscrews are especially useful where space is restricted or a shorter bolt is required.

The standard hexagon head enables straightforward installation using a 10mm spanner or socket.

Why Choose M6 x 16mm Stainless Steel Hexagon Set Screws?

Ideal for Shorter Fastening Applications

The compact 16mm length makes these fasteners particularly useful for securing metal plates, brackets, machine guards and components where longer bolts would be unnecessary or unsuitable.

A2-70 Stainless Steel Strength

Manufactured from A2 stainless steel with a property class of 70, these fasteners provide a minimum tensile strength of 700 MPa, combining mechanical strength with good corrosion resistance.

Fully Threaded for Maximum Versatility

The DIN 933 design features a metric thread extending along the shank, allowing the screw to engage with compatible M6 nuts or internally threaded components.

Good Resistance to Corrosion

A2 (304) stainless steel is suitable for many indoor and outdoor applications, particularly where exposure to moisture makes ordinary carbon steel fasteners less desirable.

Easy to Install and Remove

The traditional six-sided head provides reliable tool engagement using standard spanners and sockets, making installation and maintenance straightforward.

Common Applications for M6 x 16mm Hex Bolts

These short stainless steel hexagon head screws are commonly used for:

• Machinery and equipment assembly
• Stainless steel brackets and fittings
• Electrical enclosures and mounting plates
• Metal fabrication and engineering
• Mechanical components and machine guards
• Light-duty structural assemblies where appropriately specified
• General repairs and maintenance
• Workshop and industrial fastening applications

What Does DIN 933 Mean?

DIN 933 identifies a metric hexagon head screw with a fully threaded shank.

Unlike partially threaded hexagon bolts, the thread on a DIN 933 setscrew extends towards the underside of the head, allowing the fastener to be used in applications requiring thread engagement along most of its length.

DIN 933 has been superseded by ISO 4017, although DIN 933 remains a widely recognised product designation within the UK fastener industry.

A2 Stainless Steel or A4 Marine Grade?

A2 (304) stainless steel offers excellent general-purpose performance for engineering, construction and outdoor fastening.

For more aggressive environments involving saltwater, marine exposure or elevated chloride levels, A4 (316) marine grade stainless steel is normally the preferred material due to its improved resistance to chloride-related corrosion.
