The M3 x 30mm Hex Socket Button Head Cap Screws set offers an impressive combination of durability and convenience for a range of applications. With a thread size of 3 mm, a thread pitch of 0.5 mm, and a total length of 31.53 mm, these screws are designed to cater to various fastening needs while ensuring optimal performance in both professional and DIY projects. The button head style, characterized by a smooth, rounded top, provides a sleek finish, making it suitable for aesthetic and functional applications alike. The head diameter measures 5.50 mm with a head height of 1.53 mm, offering a low-profile solution that minimizes protrusion from the surface it fastens.
Constructed from high-quality alloy steel 40Cr and treated with a black oxide finish, these screws are designed to withstand the rigors of daily use. With a strength grade of 12.9, a hardness rating of HRC 39-44, and a remarkable tensile strength of 1220 N/mm², these fasteners exhibit significant resistance to deformation and wear. This makes them particularly suited for applications that involve mechanical stress, providing peace of mind that the integrity of the assembly will remain uncompromised over time. The inclusion of an anti-rust feature enhances their longevity, although potential users should take care to avoid conditions that may lead to corrosion.
This product does not only include the screws but also features a high-strength 2.0 mm hex key made of chrome-vanadium steel. The hex key is nickel-plated, providing additional protection against rust while ensuring a robust solution for driving the screws. The hex socket drive style is particularly user-friendly, allowing for easy engagement with the Allen wrench, thus facilitating smooth installation and removal. The compact design of the hex socket also supports a higher degree of torque, making it an ideal choice for applications requiring secure fastening.
Included is a thoughtful and functional plastic storage case that keeps all 100 screws and the hex key organized, promoting ease of access and preservation. This thoughtful packaging not only helps users to keep their workspace tidy but also protects the screws from damage, dust, and moisture. Such organization is especially beneficial in professional settings or for hobbyists who frequently work with multiple types of fasteners.
Compared to similar products on the market, this set stands out for its superior material quality and meticulous attention to dimensional accuracy, which ensures compatibility with various project specifications. While other screw sets may offer lower grades of steel or lack comprehensive packaging solutions, the M3 x 30mm Hex Socket Button Head Cap Screws maintain an edge thanks to their robust design and practical features. However, users are encouraged to ensure complete shipments, as some feedback has noted issues with missing items which may impact the overall experience.
Ultimately, the M3 x 30mm Hex Socket Button Head Cap Screws set combined with the included hex key is ideal for anyone in need of reliable, high-strength fastening solutions, whether for construction, repair, or hobbies. This set promises to meet diverse fastening needs while ensuring quality and performance remain at the forefront.
