Stainless Steel A2-70 Pan Head Combination Screws with Hexagon Socket in M3 M4 M5 Thread Sizes

Whether you are assembling furniture, securing machinery components, or carrying out general maintenance, having the right fasteners on hand can make the difference between a secure fit and a loose connection. These stainless steel A2-70 pan head combination screws come with matching hexagon nuts, so you have everything you need in one convenient set. The hexagon socket head allows for a positive drive, reducing the risk of cam-out during tightening. Made from grade A2-70 stainless steel, these screws offer reliable corrosion resistance for both indoor and sheltered outdoor use.

Features and Construction

Each combination screw is manufactured to German standard specifications and classified as A grade, indicating consistent dimensional accuracy and mechanical properties. The pan head profile sits flush against the workpiece, distributing clamping force evenly without protruding excessively. The hexagon socket drive accepts standard Allen keys, making installation straightforward with common tools.

Material and Build

The stainless steel A2-70 composition provides an austenitic structure that resists oxidation and mild chemical exposure. This grade is widely used in general engineering, automotive, and household applications where moderate corrosion resistance is sufficient. The surface is left untreated, which retains the natural metallic finish and avoids cosmetic coatings that could wear off over time.

Size and Practical Fit

Thread specifications are available in M3, M4, and M5 diameters, covering a useful range for light to medium-duty fastening. The metric threads conform to standard pitch profiles, ensuring compatibility with standard nuts, tapped holes, and threaded inserts. Each screw is paired with a matching nut of the same thread size and material grade, simplifying inventory management.

Uses and Placement

These combination screws are suitable for a wide variety of assembly tasks in workshop, home, and commercial settings. The pan head geometry works well with thin sheet materials where a countersunk head might weaken the workpiece, while the hexagon socket drive allows for good torque transfer without slipping.

Event or Professional Use

For professionals working on exhibition stands, trade show fixtures, or temporary installations, these screws provide a tidy and secure method for joining components. The pre-matched nut reduces the time spent searching for compatible hardware on site, and the stainless steel finish maintains a clean appearance under lighting.

Everyday Home Use

Around the home, these combination screws can be used to repair garden furniture, fix shelving brackets, or assemble flat-pack items where the original hardware has been lost. The M3 size works well for small electronics enclosures and model-making, while M4 and M5 suit heavier tasks such as securing hinges or brackets.

Benefits and Buying Value

Choosing a complete screw-and-nut set reduces the hassle of matching threads and materials from separate stock. The A2-70 stainless steel offers a good balance between cost and corrosion performance, making it a practical choice for many general-purpose applications.

Reuse and Low Maintenance

Stainless steel fasteners can be removed and reused on multiple occasions without significant galling, provided they are not overtightened. The untreated surface does not require special storage conditions; keeping them dry and free from abrasive dust is sufficient to maintain their usability.

Why Choose This Product

These combination screws deliver the convenience of a matched set, the reliability of German standard manufacturing, and the corrosion resistance of A2-70 stainless steel. Available in three common thread sizes, they cover a broad range of fastening tasks without the need to purchase separate bolts and nuts.
