Stainless Steel Half Round Head Pan Head Hexagon Screws, A2-70 grade corrosion resistant fasteners with 16*5.7mm dimensions, wear resistant application suitable for securing assemblies in metal, wood and plastic projects
Stainless Steel Half Round Head Pan Head Hexagon Screws for Wear-Resistant Applications

These A2-70 grade stainless steel fasteners offer a practical and durable solution for securing assemblies where corrosion resistance and wear resilience are priorities. With their semicircular head design and hexagon drive, they are suited for projects involving metal, wood, and plastic materials that require a reliable, long-lasting mechanical connection. The specified 16mm by 5.7mm size provides a precise fit for applications requiring this particular dimension, and the whitewash surface treatment contributes to a clean, finished appearance.
Features and Construction

This screw is built around core specifications that define its application suitability and performance characteristics. The construction focuses on material integrity and functional design to meet general fastening needs in various environments.
Material and Build
The screw is manufactured from Stainless Steel A2-70, a material grade known for offering a balance of corrosion resistance and mechanical strength. This makes it suitable for use in environments where moisture or general atmospheric exposure is a concern, without requiring specialised, high-alloy alternatives. The A2-70 designation indicates a specific strength grade, ensuring the fastener meets defined mechanical properties for reliable performance in typical fastening tasks.
Size and Practical Fit
The product is supplied in a size of 16mm in length and 5.7mm in diameter. This specific dimension is a key consideration for users, as it determines the material thickness it can secure and the size of the pre-drilled hole required. The semicircular head shape is designed to sit flush or with a low profile against the surface, which can be advantageous in applications where a protruding head is undesirable or could cause snagging.
Uses and Placement

The screw's design and material properties suit it for a range of fastening scenarios, from DIY projects to general maintenance and assembly work. Its application is described as wear resistant, indicating suitability for connections that may experience friction or minor abrasive forces.
Event or Professional Use
In professional settings such as light fabrication, equipment assembly, or maintenance repairs, these screws can be used to join metal brackets, secure components to wooden frames, or attach fittings to plastic housings. The corrosion resistance of A2-70 stainless steel is beneficial in workshops, outdoor enclosures, or in products that may encounter damp conditions, helping to maintain the integrity of the connection over time.
Everyday Home Use
For household projects, these screws are applicable for building or repairing furniture, fixing garden structures, assembling shelving units, or securing hardware to various materials. The hexagon drive allows for secure tightening with a standard Allen key or hex bit, which many DIY users already possess. The wear-resistant quality suggests the screw can maintain its hold in joints that might experience slight movement or vibration.
Benefits and Buying Value

The value of this product lies in its defined material specification and functional design, which address common fastening requirements without unnecessary complexity or cost associated with more specialised fasteners.
Reuse and Low Maintenance
As a stainless steel component, the screw is less prone to rusting or degrading in standard environments compared to plain steel alternatives, potentially allowing for disassembly and reuse if necessary. The whitewash surface treatment may offer a minor additional layer of protection and a uniform appearance. No specific complex care is required; the screw performs its function once installed correctly.
Why Choose This Product
This product provides a specific solution: a corrosion-resistant fastener in a defined A2-70 grade and a precise 16mm by 5.7mm size with a semicircular head. It is a practical choice when your project requires this exact combination of material properties, dimensions, and head style. It avoids the guesswork of using an incorrectly specified fastener for applications where stainless steel's properties are beneficial.
