A2-70 Stainless Steel Half Round Head Hexagon Screws in M2 to M10 Sizes

These half round head hexagon screws are supplied in Stainless Steel A2-70 with a whitewash surface treatment and a semicircular head shape. Each screw measures 16 x 5.7mm, and the listed size options range across M2.5, M2, M3, M4, M5, M6, M8, and M10, with intermediate M2 series lengths from 4mm to 25mm. The hexagon drive and half round head make them suitable for fastening, repair, assembly, and replacement tasks where a domed head profile is required. The stated application is wear resistance, and the A2-70 stainless steel grade supports use in general fixing situations. Because the pack contains one screw, buyers can choose the exact style and size for their project rather than committing to a mixed set.

Features and Construction

The construction details centre on the stated stainless steel grade, whitewash surface treatment, semicircular head, and hexagon drive. These elements define how the screw is made and how it is intended to be used. The M2 to M10 size range gives buyers a clear path to matching a screw to an existing hole or fitting. The 16 x 5.7mm measurement provides a fixed dimensional reference for checking fit before purchase.

Material and Build

Stainless Steel A2-70 is the stated material for these half round head hexagon screws. A2-70 is a recognised stainless steel designation, and the source text also lists it under strength grade and application. The whitewash surface treatment is applied to the screw, while the semicircular head shape forms the domed top profile. The hexagon drive is part of the head design, allowing the screw to be turned with a matching tool. Wear resistance is the stated application, so the screw is intended for fastening tasks where surface friction and repeated contact may occur.

Size and Practical Fit

Each screw measures 16 x 5.7mm. The available style options include M2.5, M2, M3, M4, M5, M6, M8, and M10 categories. Within the M2.5 range, listed sizes include 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, and 20mm. Within the M2 range, listed sizes include 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, 16mm, 18mm, 20mm, and 25mm. The M3, M4, M5, M6, M8, and M10 options provide larger size choices for suitable fastening points. Checking the hole diameter, thread type, and available depth against the selected size helps confirm a practical fit.

Uses and Placement

These screws suit fastening, repair, assembly, and replacement tasks where a half round head and hexagon drive are appropriate. The domed head sits above the surface, which can be useful when a flat countersunk finish is not required. The M2 to M10 size spread covers small electronic or hobby fittings as well as larger household or workshop fixings. The single-screw pack is suited to buyers who need one specific size rather than a bulk set.

Event or Professional Use

For professional or structured assembly work, the stated A2-70 stainless steel grade and whitewash finish provide a defined material specification. The semicircular head shape gives a consistent domed profile across the screw head, while the hexagon drive supports controlled tightening with the correct tool. The 16 x 5.7mm measurement and the M2 to M10 range allow a precise size match to existing threads or drilled holes. Wear resistance is the listed application, so these screws can be considered for fastening points that see repeated movement or surface contact.

Everyday Home Use

In home repair or maintenance, a single half round head hexagon screw can replace a missing or damaged fixing without buying a larger assortment. The M2.5, M2, M3, M4, M5, M6, M8, and M10 options cover common small to medium fastening needs. The domed head shape is useful where a low-profile but raised finish is acceptable. The 16 x 5.7mm size gives a clear starting point for checking against the old screw or the intended hole. The A2-70 stainless steel material and whitewash treatment are the stated construction details to consider for the surrounding environment.

Benefits and Buying Value

The main buying value comes from choosing the exact size and style needed, rather than purchasing a mixed pack with unused sizes. The A2-70 stainless steel grade, whitewash finish, semicircular head, and hexagon drive are all stated product details that help with matching and replacement. The M2 to M10 size range and the 16 x 5.7mm measurement make selection more precise.

Reuse and Low Maintenance

Stainless Steel A2-70 is the stated material, and the whitewash surface treatment is part of the specified finish. Together with the semicircular head and hexagon drive, these details define a screw that can be removed and refitted using the correct tool. The listed application of wear resistance supports use in fastening points that may experience surface contact. Keeping the screw clean and dry when not in use is a reasonable way to help maintain the stated finish. No specialist maintenance instructions are provided beyond the material and surface treatment details.
