Stainless Steel Half Round Head Hexagon Screws in A2-70 Grade for Wear Resistant Applications

These stainless steel hexagon screws are engineered for fastening tasks that demand durability and material integrity. Made from A2-70 grade stainless steel, they provide a foundation of strength and corrosion resistance suitable for various industrial, workshop, and DIY scenarios. The half round head pan head design combines a neat, finished look with the practical advantage of a hexagon drive, allowing for secure tool engagement and effective torque transfer. With a whitewash surface treatment and a specific 16mm by 5.7mm size, these screws are built to offer a straightforward and reliable mechanical solution.

Features and Construction

This product is defined by its precise material specification and design features, each contributing to its practical application. The construction details are geared towards creating a functional and lasting fastener.

Material and Build

The core material is A2-70 grade stainless steel. This is a standardised designation indicating an austenitic stainless steel with a minimum tensile strength of 700 N/mm². This grade offers a practical balance of mechanical properties and resistance to corrosion in many environments, making it a common choice for general-purpose fasteners. The application is specifically noted as 'wear resistance', suggesting suitability for connections that may experience friction or mechanical abrasion during use.

Size and Practical Fit

The product is listed with a primary size of 16*5.7mm. This typically refers to a length of 16mm and a major thread diameter or head size of 5.7mm. Crucially, a wide array of thread size options is available, allowing for precise matching to your project. The options range from finer M2.5 threads in lengths from 10mm to 20mm, core M2 threads in various lengths, and standard metric sizes from M3 up to M8. This selection ensures you can find the exact screw to fit pre-drilled holes, nuts, or components.

Uses and Placement

Given their material properties and design, these screws are suited to a range of fastening contexts, from professional settings to home workshops.

Event or Professional Use

In professional, industrial, or workshop environments, these A2-70 screws are applicable for assembling machinery fixtures, securing panels on equipment subject to vibration, or constructing frames and supports where wear resistance is beneficial. The hexagon drive is advantageous in high-torque situations or where space constraints make other drive types less practical. The stainless steel material is suitable for applications where exposure to moisture, mild chemicals, or outdoor elements is a consideration.

Everyday Home Use

For DIY enthusiasts and home improvers, these screws are well-suited for projects requiring a robust and reliable fastener. This could include assembling or repairing furniture, building sheds or garden structures, fixing bicycles, or securing household appliances and fittings. The availability of multiple thread sizes (like M4, M5, M6) makes them versatile for repairing various consumer products or undertaking custom fabrication work in a home workshop.

Benefits and Buying Value

The value of these screws lies in their material specification, functional design, and the utility offered by the extensive size selection.

Reuse and Low Maintenance

Stainless steel fasteners are known for their resistance to rust and degradation, which means they can often be removed and reused if necessary, unlike fasteners that may corrode and seize. The whitewash finish can provide an additional layer of surface protection and maintains a uniform appearance. This material choice can reduce long-term maintenance concerns for the assembled item, as the fastener itself is less likely to be a point of failure due to corrosion.

Why Choose This Product

This product provides a clear specification: A2-70 stainless steel for material performance, a hexagon drive for secure installation, a specific 16x5.7mm size, and a whitewash finish. The key differentiator is the extensive list of available thread sizes, from M2.5 to M8, which offers exceptional flexibility. Instead of sourcing screws from multiple suppliers, this single product line covers a broad range of common metric thread requirements, making it a practical and efficient choice for anyone needing a selection of durable stainless steel fasteners for various tasks.
