Stainless Steel Half Round Head Pan Head Hexagon Screws in A2-70 Grade with 16mm Length

These stainless steel hexagon screws provide practical fastening solutions where both mechanical strength and basic corrosion resistance are required. Manufactured from A2-70 grade stainless steel, they offer reliable performance in general atmospheric conditions without the need for additional protective coatings beyond their whitewash surface treatment. The half round pan head design combined with hexagon drive creates a versatile fastening option suitable for various assembly applications where a semi-flush finish is desirable. Available in multiple thread sizes ranging from M2.5 to M25, these screws cater to different fastening requirements across DIY, light fabrication, and repair scenarios.

Features and Construction

The construction of these screws focuses on providing functional fastening capability with basic corrosion protection. The A2-70 material specification ensures consistent mechanical properties while the design elements address practical installation considerations.

Material and Build

The screws are manufactured from Stainless Steel A2-70, an austenitic stainless steel grade that provides fundamental corrosion resistance suitable for many general applications. The '70' in the designation indicates a minimum tensile strength of 700 N/mm², offering adequate mechanical performance for typical fastening needs. The whitewash surface treatment provides additional surface protection and can help with identification, though it doesn't significantly alter the material's inherent corrosion resistance properties. This material choice represents a balanced option between corrosion resistance and cost-effectiveness for applications that don't require premium-grade stainless steel.

Size and Practical Fit

With dimensions of 16mm in length and 5.7mm in diameter, these screws provide a specific size option within the broader available range. The half round pan head design creates a distinctive profile that sits partially proud of the surface when installed, making it suitable for applications where countersunk holes aren't practical or desirable. The hexagon drive configuration ensures positive engagement with standard hexagon tools, allowing for reliable torque transmission during installation without the slippage risks sometimes associated with other drive types. This combination of specific dimensions and drive type creates a practical fastening solution for scenarios requiring this particular size specification.

Uses and Placement

The practical applications for these screws span both professional and domestic settings where stainless steel fasteners offer advantages over standard steel options. Their specific characteristics make them suitable for particular installation scenarios and material combinations.

Event or Professional Use

In professional environments, these A2-70 stainless steel screws find application in light fabrication, equipment assembly, and maintenance scenarios where basic corrosion resistance is beneficial but premium grades aren't necessary. The half round pan head design proves useful in situations where a flush finish isn't critical but where protrusion needs to be minimised compared to standard round heads. The hexagon drive allows for efficient installation with standard workshop tools, while the whitewash treatment can aid in visual inspection and quality control processes. These characteristics make them suitable for assembly lines, repair workshops, and light manufacturing applications.

Everyday Home Use

For domestic applications, these screws provide corrosion-resistant fastening solutions for outdoor furniture assembly, garden structure construction, and household repair projects. The A2-70 material offers sufficient protection against weathering for typical garden and outdoor use without the premium cost of higher-grade stainless steels. The half round pan head design works well for joining materials where countersinking isn't practical, such as in existing structures or with materials that don't lend themselves to countersunk preparation. The hexagon drive is accessible to most DIY enthusiasts with standard tool sets, making installation straightforward without requiring specialised drivers.

Benefits and Buying Value

The value proposition of these screws lies in their combination of basic corrosion resistance with practical installation characteristics at a point between standard steel and premium stainless options.

Reuse and Low Maintenance

The stainless steel construction allows for potential reuse in appropriate applications, as the material maintains its integrity through installation and removal cycles better than standard steel fasteners. The whitewash treatment may wear with repeated use but doesn't affect the core material properties. These screws require minimal maintenance in service, with their corrosion resistance reducing the need for protective coatings or regular inspection compared to non-stainless alternatives. This makes them suitable for applications where future disassembly might be required or where long-term outdoor exposure is anticipated without intensive maintenance regimes.

Why Choose This Product

This product offers a specific combination of A2-70 stainless steel material, half round pan head design, hexagon drive, and 16mm length that addresses particular fastening requirements. The material provides basic corrosion resistance suitable for many applications without the cost premium of higher-grade stainless steels. The half round head design offers installation flexibility where countersunk holes aren't available or practical, while the hexagon drive ensures reliable torque transmission. The specific 16mm length provides a defined fastening depth for applications requiring this measurement. Together, these characteristics create a purposeful fastening solution for scenarios matching these specific requirements.
