The M3 x 8mm Hex Socket Flat Head Cap Screws set is an essential collection for anyone looking to ensure sturdy and reliable fastening in their projects. This comprehensive package includes 100 screws along with an accompanying hex key, all neatly organized in a convenient plastic storage case. Each screw features a precise thread size of 3 mm with a pitch of 0.5 mm, and they have a total length of 8 mm. Built to meet or exceed DIN7991 standards, these screws offer versatility for various applications ranging from DIY projects to professional assembly tasks.
These flat head screws, also referred to as countersunk head screws, are designed to provide a low-profile finish that ensures they sit flush with the surface of the material being fastened. The countersunk angle of 90 degrees facilitates a seamless integration into projects, resulting in enhanced aesthetic appeal. With a head diameter of 5.85 mm and a head length of approximately 1.7 mm, these screws are engineered to maintain structural integrity while minimizing disruptions to the surface finish.
Constructed from high-quality alloy steel 40Cr, these screws have a black oxide finish that not only enhances their visual appeal but also provides excellent resistance to corrosion and wear. Achieving a strength grade of 12.9, these screws are built to endure high-stress applications. With a hardness rating between HRC 39-44 and a tensile strength of 1220 N/mm², these cap screws are ideal for heavy-duty tasks. This exceptional strength ensures confidence in their performance, regardless of the demands placed upon them.
The included hex key, made from chrome-vanadium steel and nickel plated for added strength and anti-rust properties, features a 2.0 mm hex size that perfectly fits the internal drive style of the screws. This design not only facilitates easy driving but also improves torque application during installation, making it user-friendly. The organized plastic storage case not only ensures that the screws are easily accessible but also simplifies storage, preventing loss and maintaining order in the workspace.
When comparing the M3 x 8mm Hex Socket Flat Head Cap Screws to similar products available on the market, a distinct advantage is seen in the combination of quality materials and thoughtful design. While many screws in this category may fall short in terms of strength or material durability, these cap screws distinguish themselves with their 12.9 grade strength and resistance to wear. Other competitors may also lack the included hex key, which serves as an added value to the package. This makes these screws not just practical, but a cost-effective choice for professionals and hobbyists alike.
Ultimately, this combination of thoughtful design, superior materials, and added convenience through the hex key and organized case makes the M3 x 8mm Hex Socket Flat Head Cap Screws an exceptional choice for those seeking reliability and performance in their fastening needs.
